Spring ws SOAP endpoint responds with missing fault details

I have soap-to-soap proxy server in spring using org.springframework.ws.* Both sides have identical wsdls.
I am able to pass the success response from external service to proxy consumer however there's a problem when fault message from external service gets returned.
The problem is my proxy server removes soap detail from the original response (I have no idea why). My goal is to pass the response from external service just as it is to proxy client without shortening. Anyone could help how to avoid fault detail being deleted ? Thank you in advance.
External Server response:
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<soap:Fault>
<faultcode>soap:Server</faultcode>

Endpoint:
#Endpoint
public class ServiceEndpoint {
public static final String NAMESPACE_URI="example.system.ot.managepcccfu.v2.datatypes";
#Autowired
CFUSoapClient soapClient;
#PayloadRoot(namespace = NAMESPACE_URI, localPart = "getCFUSubscriberState" )

public GetCFUSubscriberStateResponse getCFUSubscriberState(#RequestPayload GetCFUSubscriberState request) throws GetCFUSubscriberStateFaultBusinessMessage, GetCFUSubscriberStateFaultSystemMessage {
final GetCFUSubscriberStateResponse response = soapClient.getCFUSubscriberStateResponse(request);
return response;
}
}
Soap Client:
public class CFUSoapClient extends WebServiceGatewaySupport {
public GetCFUSubscriberStateResponse getCFUSubscriberStateResponse(GetCFUSubscriberState request) throws GetCFUSubscriberStateFaultBusinessMessage {
Object response = getWebServiceTemplate().marshalSendAndReceive(request);
return (GetCFUSubscriberStateResponse) response;
}
}
Config:
#Configuration
#EnableWs
public class Config extends WsConfigurerAdapter {
#Bean
public ServletRegistrationBean messageDispatcherServlet(ApplicationContext applicationContext) {
MessageDispatcherServlet servlet = new MessageDispatcherServlet();
servlet.setApplicationContext(applicationContext);
return new ServletRegistrationBean(servlet, "/ws/CFU/*");
}
#Bean(name="CFU")
public Wsdl11Definition defaultWsdl11Definition() {
SimpleWsdl11Definition wsdl11Definition = new SimpleWsdl11Definition();
wsdl11Definition.setWsdl(new ClassPathResource("/wsdl/CFU.wsdl"));
return wsdl11Definition;
}
#Bean(name = "cfuDatatypesV2")
public XsdSchema cfuDatatypesV2() {

}
#Bean
public Jaxb2Marshaller marshaller() {
Jaxb2Marshaller jaxb2Marshaller = new Jaxb2Marshaller();
jaxb2Marshaller.setContextPath("com.ot.cfu");
return jaxb2Marshaller;
}
#Bean
public CFUSoapClient soapClient() {
CFUSoapClient client = new CFUSoapClient();
client.setDefaultUri("http://localhost:41420/CFU");
client.setMarshaller(marshaller());
client.setUnmarshaller(marshaller());
// ClientInterceptor [] interceptors = new ClientInterceptor[]{new SoapClientInterceptor()};
// client.setInterceptors(interceptors);
return client;
}
}

After hours I managed to workaround this issue following wsdl definition and implemented custom exception classes wrapping the wsdl generated fault details:
#WebFault(name = "getCFUSubscriberStateFaultBusiness", targetNamespace = "example.system.ot.managepcccfu.v2.datatypes")
public class GetCFUSubscriberStateFaultBusinessMessage extends Exception {
private GetCFUSubscriberStateFaultBusiness getCFUSubscriberStateFaultBusiness;
public GetCFUSubscriberStateFaultBusinessMessage() {
super();
}
public GetCFUSubscriberStateFaultBusinessMessage(String message) {
super(message);
}
public GetCFUSubscriberStateFaultBusinessMessage(String message, java.lang.Throwable cause) {
super(message, cause);
}
public GetCFUSubscriberStateFaultBusinessMessage(String message, GetCFUSubscriberStateFaultBusiness getCFUSubscriberStateFaultBusiness) {
super(message);
this.getCFUSubscriberStateFaultBusiness = getCFUSubscriberStateFaultBusiness;
}
public GetCFUSubscriberStateFaultBusinessMessage(String message, GetCFUSubscriberStateFaultBusiness getCFUSubscriberStateFaultBusiness, java.lang.Throwable cause) {
super(message, cause);
this.getCFUSubscriberStateFaultBusiness = getCFUSubscriberStateFaultBusiness;
}
public GetCFUSubscriberStateFaultBusiness getFaultInfo() {
return this.getCFUSubscriberStateFaultBusiness;
}
}
#WebFault(name = "getCFUSubscriberStateFaultSystem", targetNamespace = "example.system.ot.managepcccfu.v2.datatypes")
public class GetCFUSubscriberStateFaultSystemMessage extends Exception {
private GetCFUSubscriberStateFaultSystem getCFUSubscriberStateFaultSystem;
public GetCFUSubscriberStateFaultSystemMessage() {
super();
}
public GetCFUSubscriberStateFaultSystemMessage(String message) {
super(message);
}
public GetCFUSubscriberStateFaultSystemMessage(String message, java.lang.Throwable cause) {
super(message, cause);
}
public GetCFUSubscriberStateFaultSystemMessage(String message, GetCFUSubscriberStateFaultSystem getCFUSubscriberStateFaultSystem) {
super(message);
this.getCFUSubscriberStateFaultSystem = getCFUSubscriberStateFaultSystem;
}
public GetCFUSubscriberStateFaultSystemMessage(String message, GetCFUSubscriberStateFaultSystem getCFUSubscriberStateFaultSystem, java.lang.Throwable cause) {
super(message, cause);
this.getCFUSubscriberStateFaultSystem = getCFUSubscriberStateFaultSystem;
}
public GetCFUSubscriberStateFaultSystem getFaultInfo() {
return this.getCFUSubscriberStateFaultSystem;
}
}
I filled the received soap fault detail into exception placeholder upon SoapFaultClientException based on type of detail:
public class CFUSoapClient extends WebServiceGatewaySupport {
public GetCFUSubscriberStateResponse getCFUSubscriberStateResponse(GetCFUSubscriberState request) throws GetCFUSubscriberStateFaultBusinessMessage, IOException, GetCFUSubscriberStateFaultSystemMessage {
try {
return (GetCFUSubscriberStateResponse) getWebServiceTemplate().marshalSendAndReceive(request);
} catch (SoapFaultClientException e) {
final Iterator<SoapFaultDetailElement> detailEntries = e.getSoapFault().getFaultDetail().getDetailEntries();
if (detailEntries.hasNext()) {
final SoapFaultDetailElement next = detailEntries.next();
final Source source = next.getSource();
final Object faultDetail = getWebServiceTemplate().getUnmarshaller().unmarshal(source);
if (faultDetail instanceof GetCFUSubscriberStateFaultBusiness) {
throw new GetCFUSubscriberStateFaultBusinessMessage(e.getSoapFault().getFaultStringOrReason(), (GetCFUSubscriberStateFaultBusiness) faultDetail, e.getCause());
} else if (faultDetail instanceof GetCFUSubscriberStateFaultSystem) {
throw new GetCFUSubscriberStateFaultSystemMessage(e.getSoapFault().getFaultStringOrReason(), (GetCFUSubscriberStateFaultSystem) faultDetail, e.getCause());
}
}
throw new RuntimeException("Unexpected error", e);
}
}
}
Eventually, I marshalled the details in the resolver class:
#Component
public class Resolver extends AbstractEndpointExceptionResolver {
private final Jaxb2Marshaller marshaller;
#Autowired
public Resolver(Jaxb2Marshaller marshaller) {
this.marshaller = marshaller;
}
#Override
protected boolean resolveExceptionInternal(MessageContext messageContext, Object endpoint, Exception e) {
if (e instanceof GetCFUSubscriberStateFaultBusinessMessage) {
final GetCFUSubscriberStateFaultBusinessMessage getCFUSubscriberStateFaultBusinessMessage = (GetCFUSubscriberStateFaultBusinessMessage) e;
final GetCFUSubscriberStateFaultBusiness faultInfo = getCFUSubscriberStateFaultBusinessMessage.getFaultInfo();
final Result result = createFaultDetailResult(messageContext, getCFUSubscriberStateFaultBusinessMessage);
marshaller.marshal(faultInfo, result);
return true;
} else if (e instanceof GetCFUSubscriberStateFaultSystemMessage) {
final GetCFUSubscriberStateFaultSystemMessage getCFUSubscriberStateFaultSystemMessage = (GetCFUSubscriberStateFaultSystemMessage) e;
final GetCFUSubscriberStateFaultSystem faultInfo = getCFUSubscriberStateFaultSystemMessage.getFaultInfo();
final Result result = createFaultDetailResult(messageContext, getCFUSubscriberStateFaultSystemMessage);
marshaller.marshal(faultInfo, result);
return true;
}
return false;
}
private Result createFaultDetailResult(MessageContext messageContext, Exception exception) {
final SoapMessage response = (SoapMessage) messageContext.getResponse();
final SoapBody soapBody = response.getSoapBody();
final SoapFault soapFault = soapBody.addServerOrReceiverFault(exception.getMessage(), Locale.ENGLISH);
final SoapFaultDetail faultDetail = soapFault.addFaultDetail();
return faultDetail.getResult();
}
}

How to make custom exception handlers working properly

I want to use custom exception handlers for my application. But, it is not working properly.
Here is my code
AuthenticationFilter.java
#Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
if (!bAuthorize) {
chain.doFilter(request, response);
return;
}
HttpServletRequest req = (HttpServletRequest) request;
String namespace = getPathParamFromRequest(req, NAMESPACE_PATH_PREFIX);
String userId = getPathParamFromRequest(req, USER_PATH_PREFIX);
AuthContext auth = null;
RequestPathContext rpc = pathsList.getMatchingContext(req.getRequestURI(), HttpMethod.valueOf(req.getMethod()));
if (rpc != null)
auth = rpc.getAuthContext();
if (auth != null) {
// Authentication process
} else {
throw new UnauthorizedException();
}
}
ApplicationExceptionHandler.java
public class ApplicationExceptionHandler {
#ExceptionHandler(UnauthorizedException.class)
public ResponseEntity<ErrorEntity> applicationxception(final UnauthorizedException e) {
ErrorEntity errorEntity = new ErrorEntity(e.getNumericErrorCode(), e.getErrorCode(), e.getErrorMessage());
return new ResponseEntity<>(errorEntity, HttpStatus.valueOf(e.getHttpStatus()));
}
}
AuthFilterRegistration.java
#Configuration
public class AuthFilterRegistration {
#Autowired
private ApplicationContext context;
#Bean
public FilterRegistrationBean<AuthenticationFilter> loggingFilter() {
FilterRegistrationBean<AuthenticationFilter> registrationBean
= new FilterRegistrationBean<>();
registrationBean.setFilter(context.getBean(AuthenticationFilter.class));
registrationBean.addUrlPatterns( "/public/*");
return registrationBean;
}
#Bean
public AuthenticationFilter getAuthFilter() {
return new AuthenticationFilter();
}
#Bean
public ApplicationExceptionHandler getErrorHandler() {
return new ApplicationExceptionHandler();
}
}
ErrorEntity.java
public class ErrorEntity extends BaseErrorEntity {
String errorMessage;
Map<String, String> messageVariables;
public ErrorEntity() {
}
public ErrorEntity(int numericErrorCode, String errorCode, String errorMessage) {
this(numericErrorCode, errorCode, errorMessage, null);
}
public ErrorEntity(int numericErrorCode, String errorCode, String errorMessage, Map<String, String> messageVariables) {
this.numericErrorCode = numericErrorCode;
this.errorCode = errorCode;
this.errorMessage = errorMessage;
this.messageVariables = messageVariables;
}
}
Using those code, I want to have an exception error like this
{
"numericErrorCode": 2001,
"errorCode": "errors.net.myproject.platform.unauthorized",
"errorMessage": "unauthorized"
}
which is the instance of ErrorEntity, but I got this output
{
"timestamp": "2019-02-01T04:41:14.337+0000",
"status": 500,
"error": "Internal Server Error",
"message": "unauthorized",
}
From the example it is clear that I cannot override the default Java exception completely. Only the message part that is altered successfully. Do I miss something here?

import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.mvc.method.annotation.ResponseEntityExceptionHandler;
#ControllerAdvice
public class ApplicationExceptionHandler extends ResponseEntityExceptionHandler {
#ResponseBody
#ExceptionHandler(UnauthorizedException.class)
public ResponseEntity<ErrorEntity> applicationxception(final UnauthorizedException e) {
ErrorEntity errorEntity = new ErrorEntity(e.getNumericErrorCode(), e.getErrorCode(), e.getErrorMessage());
return new ResponseEntity<>(errorEntity, HttpStatus.valueOf(e.getHttpStatus()));
}
#ResponseBody
#ExceptionHandler(RetrievedProfileException.class)
public ResponseEntity<ErrorEntity> applicationexception(final RetrievedProfileException e) {
ErrorEntity errorEntity = new ErrorEntity(e.getNumericErrorCode(), e.getErrorCode(), e.getErrorMessage());
return new ResponseEntity<>(errorEntity, HttpStatus.valueOf(e.getHttpStatus()));
}
I just extend this class org.springframework.web.servlet.mvc.method.annotation.ResponseEntityExceptionHandler because its pre- requsite
Secondly i used #ControllerAdvice
and lastly i used #ResponseBody
Use Exception Handler this way plus you should override the exception in this way.

Jhipster logging [duplicate]

I'm working on REST API with spring boot. I need to log all requests with input params (with methods, eg. GET, POST, etc.), request path, query string, corresponding class method of this request, also response of this action, both success and errors. For example:
Successful request:
http://example.com/api/users/1
Log should look something like this:
{
HttpStatus: 200,
path: "api/users/1",
method: "GET",
clientIp: "0.0.0.0",
accessToken: "XHGu6as5dajshdgau6i6asdjhgjhg",
method: "UsersController.getUser",
arguments: {
id: 1
},
response: {
user: {
id: 1,
username: "user123",
email: "user123#example.com"
}
},
exceptions: []
}
Or request with error:
http://example.com/api/users/9999
Log should be something like this:
{
HttpStatus: 404,
errorCode: 101,
path: "api/users/9999",
method: "GET",
clientIp: "0.0.0.0",
accessToken: "XHGu6as5dajshdgau6i6asdjhgjhg",
method: "UsersController.getUser",
arguments: {
id: 9999
},
returns: {
},
exceptions: [
{
exception: "UserNotFoundException",
message: "User with id 9999 not found",
exceptionId: "adhaskldjaso98d7324kjh989",
stacktrace: ...................
]
}
I want Request/Response to be a single entity, with custom information related to this entity, both in successful and error cases.
What is best practice in spring to achieve this, may be with filters? if yes, can you provide concrete example?
I've played with #ControllerAdvice and #ExceptionHandler, but as I mentioned, I need to handle all success and error requests in single place (and single log).

Don't write any Interceptors, Filters, Components, Aspects, etc., this is a very common problem and has been solved many times over.
Spring Boot has a modules called Actuator, which provides HTTP request logging out of the box. There's an endpoint mapped to /trace (SB1.x) or /actuator/httptrace (SB2.0+) which will show you last 100 HTTP requests. You can customize it to log each request, or write to a DB.
To get the endpoints you want, you'll need the spring-boot-starter-actuator dependency, and also to "whitelist" the endpoints you're looking for, and possibly setup or disable security for it.
Also, where will this application run? Will you be using a PaaS? Hosting providers, Heroku for example, provide request logging as part of their service and you don't need to do any coding whatsoever then.

Spring already provides a filter that does this job. Add following bean to your config
#Bean
public CommonsRequestLoggingFilter requestLoggingFilter() {
CommonsRequestLoggingFilter loggingFilter = new CommonsRequestLoggingFilter();
loggingFilter.setIncludeClientInfo(true);
loggingFilter.setIncludeQueryString(true);
loggingFilter.setIncludePayload(true);
loggingFilter.setMaxPayloadLength(64000);
return loggingFilter;
}
Don't forget to change log level of org.springframework.web.filter.CommonsRequestLoggingFilter to DEBUG.

You could use javax.servlet.Filter if there wasn't a requirement to log java method that been executed.
But with this requirement you have to access information stored in handlerMapping of DispatcherServlet. That said, you can override DispatcherServlet to accomplish logging of request/response pair.
Below is an example of idea that can be further enhanced and adopted to your needs.
public class LoggableDispatcherServlet extends DispatcherServlet {
private final Log logger = LogFactory.getLog(getClass());
#Override
protected void doDispatch(HttpServletRequest request, HttpServletResponse response) throws Exception {
if (!(request instanceof ContentCachingRequestWrapper)) {
request = new ContentCachingRequestWrapper(request);
}
if (!(response instanceof ContentCachingResponseWrapper)) {
response = new ContentCachingResponseWrapper(response);
}
HandlerExecutionChain handler = getHandler(request);
try {
super.doDispatch(request, response);
} finally {
log(request, response, handler);
updateResponse(response);
}
}
private void log(HttpServletRequest requestToCache, HttpServletResponse responseToCache, HandlerExecutionChain handler) {
LogMessage log = new LogMessage();
log.setHttpStatus(responseToCache.getStatus());
log.setHttpMethod(requestToCache.getMethod());
log.setPath(requestToCache.getRequestURI());
log.setClientIp(requestToCache.getRemoteAddr());
log.setJavaMethod(handler.toString());
log.setResponse(getResponsePayload(responseToCache));
logger.info(log);
}
private String getResponsePayload(HttpServletResponse response) {
ContentCachingResponseWrapper wrapper = WebUtils.getNativeResponse(response, ContentCachingResponseWrapper.class);
if (wrapper != null) {
byte[] buf = wrapper.getContentAsByteArray();
if (buf.length > 0) {
int length = Math.min(buf.length, 5120);
try {
return new String(buf, 0, length, wrapper.getCharacterEncoding());
}
catch (UnsupportedEncodingException ex) {
// NOOP
}
}
}
return "[unknown]";
}
private void updateResponse(HttpServletResponse response) throws IOException {
ContentCachingResponseWrapper responseWrapper =
WebUtils.getNativeResponse(response, ContentCachingResponseWrapper.class);
responseWrapper.copyBodyToResponse();
}
}
HandlerExecutionChain - contains the information about request handler.
You then can register this dispatcher as following:
#Bean
public ServletRegistrationBean dispatcherRegistration() {
return new ServletRegistrationBean(dispatcherServlet());
}
#Bean(name = DispatcherServletAutoConfiguration.DEFAULT_DISPATCHER_SERVLET_BEAN_NAME)
public DispatcherServlet dispatcherServlet() {
return new LoggableDispatcherServlet();
}
And here's the sample of logs:
http http://localhost:8090/settings/test
i.g.m.s.s.LoggableDispatcherServlet : LogMessage{httpStatus=500, path='/error', httpMethod='GET', clientIp='127.0.0.1', javaMethod='HandlerExecutionChain with handler [public org.springframework.http.ResponseEntity<java.util.Map<java.lang.String, java.lang.Object>> org.springframework.boot.autoconfigure.web.BasicErrorController.error(javax.servlet.http.HttpServletRequest)] and 3 interceptors', arguments=null, response='{"timestamp":1472475814077,"status":500,"error":"Internal Server Error","exception":"java.lang.RuntimeException","message":"org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.RuntimeException","path":"/settings/test"}'}
http http://localhost:8090/settings/params
i.g.m.s.s.LoggableDispatcherServlet : LogMessage{httpStatus=200, path='/settings/httpParams', httpMethod='GET', clientIp='127.0.0.1', javaMethod='HandlerExecutionChain with handler [public x.y.z.DTO x.y.z.Controller.params()] and 3 interceptors', arguments=null, response='{}'}
http http://localhost:8090/123
i.g.m.s.s.LoggableDispatcherServlet : LogMessage{httpStatus=404, path='/error', httpMethod='GET', clientIp='127.0.0.1', javaMethod='HandlerExecutionChain with handler [public org.springframework.http.ResponseEntity<java.util.Map<java.lang.String, java.lang.Object>> org.springframework.boot.autoconfigure.web.BasicErrorController.error(javax.servlet.http.HttpServletRequest)] and 3 interceptors', arguments=null, response='{"timestamp":1472475840592,"status":404,"error":"Not Found","message":"Not Found","path":"/123"}'}
UPDATE
In case of errors Spring does automatic error handling. Therefore, BasicErrorController#error is shown as request handler. If you want to preserve original request handler, then you can override this behavior at spring-webmvc-4.2.5.RELEASE-sources.jar!/org/springframework/web/servlet/DispatcherServlet.java:971 before #processDispatchResult is called, to cache original handler.

The Logbook library is specifically made for logging HTTP requests and responses. It supports Spring Boot using a special starter library.
To enable logging in Spring Boot all you need to do is adding the library to your project's dependencies. For example assuming you are using Maven:
<dependency>
<groupId>org.zalando</groupId>
<artifactId>logbook-spring-boot-starter</artifactId>
<version>1.5.0</version>
</dependency>
By default the logging output looks like this:
{
"origin" : "local",
"correlation" : "52e19498-890c-4f75-a06c-06ddcf20836e",
"status" : 200,
"headers" : {
"X-Application-Context" : [
"application:8088"
],
"Content-Type" : [
"application/json;charset=UTF-8"
],
"Transfer-Encoding" : [
"chunked"
],
"Date" : [
"Sun, 24 Dec 2017 13:10:45 GMT"
]
},
"body" : {
"thekey" : "some_example"
},
"duration" : 105,
"protocol" : "HTTP/1.1",
"type" : "response"
}
It does however not output the class name that is handling the request. The library does have some interfaces for writing custom loggers.
Notes
In the meantime the library has significantly evolved, current version is 2.4.1, see https://github.com/zalando/logbook/releases. E.g. the default ouput format has changed, and can be configured, filtered, etc.
Do NOT forget to set the log level to TRACE, else you won't see anything:
logging:
level:
org.zalando.logbook: TRACE

I had defined logging level in application.properties to print requests/responses, method url in the log file
logging.level.org.springframework.web=DEBUG
logging.level.org.hibernate.SQL=INFO
logging.file=D:/log/myapp.log
I had used Spring Boot.

Here is how I do it in spring data rest
by using
org.springframework.web.util.ContentCachingRequestWrapper and
org.springframework.web.util.ContentCachingResponseWrapper

try {

} catch (UnsupportedEncodingException ex) {
return "Unsupported Encoding";
}
}

// We CANNOT simply read the request payload here, because then the InputStream would be consumed and cannot be read again by the actual processing/server.
// String reqBody = DoogiesUtil._stream2String(request.getInputStream()); // THIS WOULD NOT WORK!
// So we need to apply some stronger magic here :-)
ContentCachingRequestWrapper wrappedRequest = new ContentCachingRequestWrapper(request);
ContentCachingResponseWrapper wrappedResponse = new ContentCachingResponseWrapper(response);
filterChain.doFilter(wrappedRequest, wrappedResponse); // ======== This performs the actual request!
long duration = System.currentTimeMillis() - startTime;

if (requestBody.length() > 0) {
this.logger.debug(" Request body:\n" +requestBody);
}
this.logger.debug("<= " + reqInfo + ": returned status=" + response.getStatus() + " in "+duration + "ms");
if (includeResponsePayload) {
byte[] buf = wrappedResponse.getContentAsByteArray();
this.logger.debug(" Response body:\n"+getContentAsString(buf, this.maxPayloadLength, response.getCharacterEncoding()));
}
wrappedResponse.copyBodyToResponse(); // IMPORTANT: copy content of response back into original response
}
}

If you dont mind trying Spring AOP, this is something I have been exploring for logging purposes and it works pretty well for me. It wont log requests that have not been defined and failed request attempts though.
Add these three dependencies
spring-aop, aspectjrt, aspectjweaver
Add this to your xml config file <aop:aspectj-autoproxy/>
Create an annotation which can be used as a pointcut
#Retention(RetentionPolicy.RUNTIME)
#Target({ElementType.METHOD,ElementType.TYPE})
public #interface EnableLogging {
ActionType actionType();
}
Now annotate all your rest API methods which you want to log
#EnableLogging(actionType = ActionType.SOME_EMPLOYEE_ACTION)
#Override
public Response getEmployees(RequestDto req, final String param) {
...
}
Now on to the Aspect. component-scan the package which this class is in.
#Aspect
#Component
public class Aspects {
#AfterReturning(pointcut = "execution(#co.xyz.aspect.EnableLogging * *(..)) && #annotation(enableLogging) && args(reqArg, reqArg1,..)", returning = "result")
public void auditInfo(JoinPoint joinPoint, Object result, EnableLogging enableLogging, Object reqArg, String reqArg1) {
HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes())
.getRequest();
if (result instanceof Response) {
Response responseObj = (Response) result;
String requestUrl = request.getScheme() + "://" + request.getServerName()
+ ":" + request.getServerPort() + request.getContextPath() + request.getRequestURI()
+ "?" + request.getQueryString();
String clientIp = request.getRemoteAddr();
String clientRequest = reqArg.toString();
int httpResponseStatus = responseObj.getStatus();
responseObj.getEntity();
// Can log whatever stuff from here in a single spot.
}
#AfterThrowing(pointcut = "execution(#co.xyz.aspect.EnableLogging * *(..)) && #annotation(enableLogging) && args(reqArg, reqArg1,..)", throwing="exception")
public void auditExceptionInfo(JoinPoint joinPoint, Throwable exception, EnableLogging enableLogging, Object reqArg, String reqArg1) {
HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes())
.getRequest();
String requestUrl = request.getScheme() + "://" + request.getServerName()
+ ":" + request.getServerPort() + request.getContextPath() + request.getRequestURI()
+ "?" + request.getQueryString();
exception.getMessage();
exception.getCause();
exception.printStackTrace();
exception.getLocalizedMessage();
// Can log whatever exceptions, requests, etc from here in a single spot.
}
}
#AfterReturning advice runs when a matched method execution returns
normally.
#AfterThrowing advice runs when a matched method execution exits by
throwing an exception.
If you want to read in detail read through this.

Currently Spring Boot has the Actuator feature to get the logs of requests and responses.
But you can also get the logs using Aspect(AOP).
Aspect provides you with annotations like: #Before, #AfterReturning, #AfterThrowing etc.
#Before logs the request, #AfterReturning logs the response and #AfterThrowing logs the error message,
You may not need all endpoints' log, so you can apply some filters on the packages.
Here are some examples:
For Request:
#Before("within(your.package.where.endpoints.are..*)")
public void endpointBefore(JoinPoint p) {
if (log.isTraceEnabled()) {
log.trace(p.getTarget().getClass().getSimpleName() + " " + p.getSignature().getName() + " START");
Object[] signatureArgs = p.getArgs();
ObjectMapper mapper = new ObjectMapper();
mapper.enable(SerializationFeature.INDENT_OUTPUT);
try {
if (signatureArgs[0] != null) {
log.trace("\nRequest object: \n" + mapper.writeValueAsString(signatureArgs[0]));
}
} catch (JsonProcessingException e) {
}
}
}
Here #Before("within(your.package.where.endpoints.are..*)") has the package path. All endpoints within this package will generate the log.
For Response:
#AfterReturning(value = ("within(your.package.where.endpoints.are..*)"),
returning = "returnValue")
public void endpointAfterReturning(JoinPoint p, Object returnValue) {
if (log.isTraceEnabled()) {
ObjectMapper mapper = new ObjectMapper();
mapper.enable(SerializationFeature.INDENT_OUTPUT);
try {
log.trace("\nResponse object: \n" + mapper.writeValueAsString(returnValue));
} catch (JsonProcessingException e) {
System.out.println(e.getMessage());
}
log.trace(p.getTarget().getClass().getSimpleName() + " " + p.getSignature().getName() + " END");
}
}
Here #AfterReturning("within(your.package.where.endpoints.are..*)") has the package path. All endpoints within this package will generate the log. Also Object returnValue contains the response.
For Exception:
#AfterThrowing(pointcut = ("within(your.package.where.endpoints.are..*)"), throwing = "e")
public void endpointAfterThrowing(JoinPoint p, Exception e) throws DmoneyException {
if (log.isTraceEnabled()) {
System.out.println(e.getMessage());
e.printStackTrace();
log.error(p.getTarget().getClass().getSimpleName() + " " + p.getSignature().getName() + " " + e.getMessage());
}
}
Here #AfterThrowing(pointcut = ("within(your.package.where.endpoints.are..*)"), throwing = "e") has the package path. All endpoints within this package will generate the log. Also Exception e contains the error response.
Here is the full code:
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import org.apache.log4j.Logger;
import org.aspectj.lang.JoinPoint;

import org.springframework.core.annotation.Order;
import org.springframework.stereotype.Component;
#Aspect
#Order(1)
#Component
#ConditionalOnExpression("${endpoint.aspect.enabled:true}")
public class EndpointAspect {
static Logger log = Logger.getLogger(EndpointAspect.class);
#Before("within(your.package.where.is.endpoint..*)")
public void endpointBefore(JoinPoint p) {
if (log.isTraceEnabled()) {
log.trace(p.getTarget().getClass().getSimpleName() + " " + p.getSignature().getName() + " START");
Object[] signatureArgs = p.getArgs();
ObjectMapper mapper = new ObjectMapper();
mapper.enable(SerializationFeature.INDENT_OUTPUT);
try {
if (signatureArgs[0] != null) {
log.trace("\nRequest object: \n" + mapper.writeValueAsString(signatureArgs[0]));
}
} catch (JsonProcessingException e) {
}
}
}
#AfterReturning(value = ("within(your.package.where.is.endpoint..*)"),
returning = "returnValue")
public void endpointAfterReturning(JoinPoint p, Object returnValue) {
if (log.isTraceEnabled()) {
ObjectMapper mapper = new ObjectMapper();
mapper.enable(SerializationFeature.INDENT_OUTPUT);
try {
log.trace("\nResponse object: \n" + mapper.writeValueAsString(returnValue));
} catch (JsonProcessingException e) {
System.out.println(e.getMessage());
}
log.trace(p.getTarget().getClass().getSimpleName() + " " + p.getSignature().getName() + " END");
}
}
#AfterThrowing(pointcut = ("within(your.package.where.is.endpoint..*)"), throwing = "e")
public void endpointAfterThrowing(JoinPoint p, Exception e) throws Exception {
if (log.isTraceEnabled()) {
System.out.println(e.getMessage());
e.printStackTrace();
log.error(p.getTarget().getClass().getSimpleName() + " " + p.getSignature().getName() + " " + e.getMessage());
}
}
}
Here, using #ConditionalOnExpression("${endpoint.aspect.enabled:true}") you can enable/disable the log. just add endpoint.aspect.enabled:true into the application.property and control the log
More info about AOP visit here:
Spring docs about AOP
Sample article about AOP

After adding Actuators to the spring boot bassed application you have /trace endpoint available with latest requests informations. This endpoint is working based on TraceRepository and default implementation is InMemoryTraceRepository that saves last 100 calls. You can change this by implementing this interface by yourself and make it available as a Spring bean. For example to log all requests to log (and still use default implementation as a basic storage for serving info on /trace endpoint) I'm using this kind of implementation:
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.actuate.trace.InMemoryTraceRepository;
import org.springframework.boot.actuate.trace.Trace;
import org.springframework.boot.actuate.trace.TraceRepository;
import org.springframework.stereotype.Component;
import java.util.List;
import java.util.Map;
#Component
public class LoggingTraceRepository implements TraceRepository {
private static final Logger LOG = LoggerFactory.getLogger(LoggingTraceRepository.class);
private final TraceRepository delegate = new InMemoryTraceRepository();
#Override
public List<Trace> findAll() {
return delegate.findAll();
}
#Override
public void add(Map<String, Object> traceInfo) {
LOG.info(traceInfo.toString());
this.delegate.add(traceInfo);
}
}
This traceInfo map contains basic informations about request and response in this kind of form:
{method=GET, path=/api/hello/John, headers={request={host=localhost:8080, user-agent=curl/7.51.0, accept=*/*}, response={X-Application-Context=application, Content-Type=text/plain;charset=UTF-8, Content-Length=10, Date=Wed, 29 Mar 2017 20:41:21 GMT, status=200}}}. There is NO response content here.
EDIT! Logging POST data
You can access POST data by overriding WebRequestTraceFilter, but don't think it is a good idea (e.g. all uploaded file content will go to logs)
Here is sample code, but don't use it:
package info.fingo.nuntius.acuate.trace;
import org.apache.commons.io.IOUtils;
import org.springframework.boot.actuate.trace.TraceProperties;
import org.springframework.boot.actuate.trace.TraceRepository;
import org.springframework.boot.actuate.trace.WebRequestTraceFilter;
import org.springframework.stereotype.Component;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import java.io.IOException;
import java.nio.charset.Charset;
import java.util.LinkedHashMap;
import java.util.Map;
#Component
public class CustomWebTraceFilter extends WebRequestTraceFilter {
public CustomWebTraceFilter(TraceRepository repository, TraceProperties properties) {
super(repository, properties);
}
#Override
protected Map<String, Object> getTrace(HttpServletRequest request) {
Map<String, Object> trace = super.getTrace(request);
String multipartHeader = request.getHeader("content-type");
if (multipartHeader != null && multipartHeader.startsWith("multipart/form-data")) {
Map<String, Object> parts = new LinkedHashMap<>();
try {
request.getParts().forEach(
part -> {
try {
parts.put(part.getName(), IOUtils.toString(part.getInputStream(), Charset.forName("UTF-8")));
} catch (IOException e) {
e.printStackTrace();
}
}
);
} catch (IOException | ServletException e) {
e.printStackTrace();
}
if (!parts.isEmpty()) {
trace.put("multipart-content-map", parts);
}
}
return trace;
}
}

Here my solution (Spring 2.0.x)
Add the maven dependency:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
Edit the application.properties and add the following line:
management.endpoints.web.exposure.include=*
Once your spring boot application is started you can track the latest 100 http requests by calling this url:
http://localhost:8070/actuator/httptrace

You can also configure a custom Spring interceptor HandlerInterceptorAdapter for a simplified implementation of pre-only/post-only interceptors:
#Component
public class CustomHttpInterceptor extends HandlerInterceptorAdapter {
#Override
public boolean preHandle (final HttpServletRequest request, final HttpServletResponse response,
final Object handler)
throws Exception {
// Logs here
return super.preHandle(request, response, handler);
}
#Override
public void afterCompletion(final HttpServletRequest request, final HttpServletResponse response,
final Object handler, final Exception ex) {
// Logs here
}
}
Then, you register as many interceptors as you want:
#Configuration
public class WebMvcConfig implements WebMvcConfigurer {
#Autowired
CustomHttpInterceptor customHttpInterceptor;
#Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(customHttpInterceptor).addPathPatterns("/endpoints");
}
}
Note: just like stated by #Robert, you need to pay attention to the specific implementations of HttpServletRequest and HttpServletResponse your application is using.
For example, for apps using the ShallowEtagHeaderFilter, the response implementation would be a ContentCachingResponseWrapper, so you'd have:
#Component
public class CustomHttpInterceptor extends HandlerInterceptorAdapter {
private static final Logger LOGGER = LoggerFactory.getLogger(CustomHttpInterceptor.class);
private static final int MAX_PAYLOAD_LENGTH = 1000;
#Override
public void afterCompletion(final HttpServletRequest request, final HttpServletResponse response,
final Object handler, final Exception ex) {
final byte[] contentAsByteArray = ((ContentCachingResponseWrapper) response).getContentAsByteArray();
LOGGER.info("Request body:\n" + getContentAsString(contentAsByteArray, response.getCharacterEncoding()));
}
private String getContentAsString(byte[] buf, String charsetName) {
if (buf == null || buf.length == 0) {
return "";
}
try {
int length = Math.min(buf.length, MAX_PAYLOAD_LENGTH);
return new String(buf, 0, length, charsetName);
} catch (UnsupportedEncodingException ex) {
return "Unsupported Encoding";
}
}
}

the code pasted below works with my tests and can be downloaded from my [github project][1], sharing after applying a solution based on that on a production project.
#Configuration
public class LoggingFilter extends GenericFilterBean {
/**
* It's important that you actually register your filter this way rather then just annotating it
* as #Component as you need to be able to set for which "DispatcherType"s to enable the filter
* (see point *1*)
*
* #return
*/
#Bean
public FilterRegistrationBean<LoggingFilter> initFilter() {
FilterRegistrationBean<LoggingFilter> registrationBean = new FilterRegistrationBean<>();
registrationBean.setFilter(new LoggingFilter());
// *1* make sure you sett all dispatcher types if you want the filter to log upon
registrationBean.setDispatcherTypes(EnumSet.allOf(DispatcherType.class));
// *2* this should put your filter above any other filter
registrationBean.setOrder(Ordered.HIGHEST_PRECEDENCE);
return registrationBean;
}
#Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
throws IOException, ServletException {
ContentCachingRequestWrapper wreq =
new ContentCachingRequestWrapper(
(HttpServletRequest) request);
ContentCachingResponseWrapper wres =
new ContentCachingResponseWrapper(
(HttpServletResponse) response);
try {
// let it be ...
chain.doFilter(wreq, wres);
// makes sure that the input is read (e.g. in 404 it may not be)
while (wreq.getInputStream().read() >= 0);
System.out.printf("=== REQUEST%n%s%n=== end request%n",
new String(wreq.getContentAsByteArray()));
// Do whatever logging you wish here, in this case I'm writing request
// and response to system out which is probably not what you wish to do
System.out.printf("=== RESPONSE%n%s%n=== end response%n",
new String(wres.getContentAsByteArray()));
// this is specific of the "ContentCachingResponseWrapper" we are relying on,
// make sure you call it after you read the content from the response
wres.copyBodyToResponse();
// One more point, in case of redirect this will be called twice! beware to handle that
// somewhat
} catch (Throwable t) {
// Do whatever logging you whish here, too
// here you should also be logging the error!!!
throw t;
}
}
}

If somebody still need it here is simple implementation with Spring HttpTrace Actuator. But as they have told upper it doesn't log bodies.
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang3.builder.ToStringBuilder;
import org.springframework.boot.actuate.trace.http.HttpTrace;
import org.springframework.boot.actuate.trace.http.InMemoryHttpTraceRepository;
import org.springframework.stereotype.Repository;
#Slf4j
#Repository
public class LoggingInMemoryHttpTraceRepository extends InMemoryHttpTraceRepository {
public void add(HttpTrace trace) {
super.add(trace);
log.info("Trace:" + ToStringBuilder.reflectionToString(trace));
log.info("Request:" + ToStringBuilder.reflectionToString(trace.getRequest()));
log.info("Response:" + ToStringBuilder.reflectionToString(trace.getResponse()));
}
}

#hahn's answer required a bit of modification for it to work for me, but it is by far the most customizable thing I could get.
It didn't work for me, probably because I also have a HandlerInterceptorAdapter[??] but I kept getting a bad response from the server in that version. Here's my modification of it.
public class LoggableDispatcherServlet extends DispatcherServlet {
private final Log logger = LogFactory.getLog(getClass());
#Override
protected void doDispatch(HttpServletRequest request, HttpServletResponse response) throws Exception {
long startTime = System.currentTimeMillis();
try {
super.doDispatch(request, response);
} finally {
log(new ContentCachingRequestWrapper(request), new ContentCachingResponseWrapper(response),
System.currentTimeMillis() - startTime);
}
}
private void log(HttpServletRequest requestToCache, HttpServletResponse responseToCache, long timeTaken) {
int status = responseToCache.getStatus();
JsonObject jsonObject = new JsonObject();
jsonObject.addProperty("httpStatus", status);
jsonObject.addProperty("path", requestToCache.getRequestURI());
jsonObject.addProperty("httpMethod", requestToCache.getMethod());
jsonObject.addProperty("timeTakenMs", timeTaken);
jsonObject.addProperty("clientIP", requestToCache.getRemoteAddr());
if (status > 299) {
String requestBody = null;
try {
requestBody = requestToCache.getReader().lines().collect(Collectors.joining(System.lineSeparator()));
} catch (IOException e) {
e.printStackTrace();
}
jsonObject.addProperty("requestBody", requestBody);
jsonObject.addProperty("requestParams", requestToCache.getQueryString());
jsonObject.addProperty("tokenExpiringHeader",
responseToCache.getHeader(ResponseHeaderModifierInterceptor.HEADER_TOKEN_EXPIRING));
}
logger.info(jsonObject);
}
}

Has there been any development with Actuator HTTP Trace since the initial question was posted i.e. is there a way to enrich it with the response body?
What about enriching it with custom metadata from MDC or from Spring-Sleuth or Zipkin, such as traceId and spanId?
Also for me Actuator HTTP Trace didn't work Spring Boot 2.2.3, and I found the fix here: https://juplo.de/actuator-httptrace-does-not-work-with-spring-boot-2-2/
pom.xml
<dependency>
<groupId>org.springframework.boot
<artifactId>spring-boot-starter-actuator
</dependency>
application.properties
management.endpoints.web.exposure.include=httptrace
The fix:
The simple fix for this problem is, to add a #Bean of type
InMemoryHttpTraceRepository to your #Configuration-class:
#Bean
public HttpTraceRepository htttpTraceRepository()
{
return new InMemoryHttpTraceRepository();
}
The Explanation:
The cause of this problem is not a bug, but a legitimate change in the
default configuration. Unfortunately, this change is not noted in the
according section of the documentation. Instead it is burried in the
Upgrade Notes for Spring Boot 2.2
The default-implementation stores the captured data in memory. Hence,
it consumes much memory, without the user knowing, or even worse:
needing it. This is especially undesirable in cluster environments,
where memory is a precious good. And remember: Spring Boot was
invented to simplify cluster deployments!
That is, why this feature is now turned of by default and has to be
turned on by the user explicitly, if needed.

If you are seeing only part of your request payload, you need to call the setMaxPayloadLength function as it defaults to showing only 50 characters in your request body. Also, setting setIncludeHeaders to false is a good idea if you don't want to log your auth headers!
#Bean
public CommonsRequestLoggingFilter requestLoggingFilter() {
CommonsRequestLoggingFilter loggingFilter = new CommonsRequestLoggingFilter();
loggingFilter.setIncludeClientInfo(false);
loggingFilter.setIncludeQueryString(false);
loggingFilter.setIncludePayload(true);
loggingFilter.setIncludeHeaders(false);
loggingFilter.setMaxPayloadLength(500);
return loggingFilter;
}

As suggested previously, Logbook is just about perfect for this, but I did have a little trouble setting it up when using Java modules, due to a split package between logbook-api and logbook-core.
For my Gradle + Spring Boot project, I needed
build.gradle
dependencies {
compileOnly group: 'org.zalando', name: 'logbook-api', version: '2.4.1'
runtimeOnly group: 'org.zalando', name: 'logbook-spring-boot-starter', version: '2.4.1'
//...
}
logback-spring.xml
<configuration>
<!-- HTTP Requests and Responses -->
<logger name="org.zalando.logbook" level="trace" />
</configuration>

In order to log all the requests with input parameters and body, we can use filters and interceptors. But while using a filter or interceptor, we cannot print the request body multiple times.
The better way is we can use spring-AOP. By using this we can decouple the logging mechanism from the application. AOP can be used for logging Input and output of each method in the application.
My solution is:
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.aspectj.lang.reflect.CodeSignature;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
import com.fasterxml.jackson.databind.ObjectMapper;
#Aspect
#Component
public class LoggingAdvice {
private static final Logger logger =
LoggerFactory.getLogger(LoggingAdvice.class);
//here we can provide any methodName, packageName, className
#Pointcut(value = "execution(* com.package.name.*.*.*(..) )")
public void myPointcut() {
}
#Around("myPointcut()")
public Object applicationLogger(ProceedingJoinPoint pjt) throws Throwable {
ObjectMapper mapper = new ObjectMapper();
String methodName = pjt.getSignature().getName();
String className = pjt.getTarget().getClass().toString();
String inputParams = this.getInputArgs(pjt ,mapper);
logger.info("method invoked from " + className + " : " + methodName + "--Request Payload::::"+inputParams);
Object object = pjt.proceed();
try {
logger.info("Response Object---" + mapper.writeValueAsString(object));
} catch (Exception e) {
}
return object;
}
private String getInputArgs(ProceedingJoinPoint pjt,ObjectMapper mapper) {
Object[] array = pjt.getArgs();
CodeSignature signature = (CodeSignature) pjt.getSignature();
StringBuilder sb = new StringBuilder();
sb.append("{");
int i = 0;
String[] parameterNames = signature.getParameterNames();
int maxArgs = parameterNames.length;
for (String name : signature.getParameterNames()) {
sb.append("[").append(name).append(":");
try {
sb.append(mapper.writeValueAsString(array[i])).append("]");
if(i != maxArgs -1 ) {
sb.append(",");
}
} catch (Exception e) {
sb.append("],");
}
i++;
}
return sb.append("}").toString();
}
}

Note
#Bean
public CommonsRequestLoggingFilter requestLoggingFilter() {
...
}
approach will not work with spring security filter chains.
You have to manually add CommonsRequestLoggingFilter like
protected void configure(HttpSecurity http) throws Exception {
HttpSecurity filter = http
.cors().and().addFilterBefore(new CommonsRequestLoggingFilter(), CorsFilter.class);
}

if you use Tomcat in your boot app here is org.apache.catalina.filters.RequestDumperFilter in a class path for you. (but it will not provide you "with exceptions in single place").

If you have Spring boot Config server configured then just enable Debug logger for class :
Http11InputBuffer.Http11InputBuffer.java
Debugs will log all the requests and responses for every request

I created a file called LoggingConfig.java with contents:
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.filter.CommonsRequestLoggingFilter;
#Configuration
public class LoggingConfig {
#Bean
public CommonsRequestLoggingFilter requestLoggingFilter() {
final CommonsRequestLoggingFilter loggingFilter = new CommonsRequestLoggingFilter();
loggingFilter.setIncludeClientInfo(true);
loggingFilter.setIncludeQueryString(true);
loggingFilter.setIncludePayload(true);
loggingFilter.setMaxPayloadLength(32768);
return loggingFilter;
}
}
In application.properties I added:
logging.level.org.springframework.web.filter.CommonsRequestLoggingFilter=DEBUG

Logging Request + payload in a CUSTOM FORMAT:
For a custom format, just override the super implementation of the Spring logger Bean - org/springframework/web/filter/AbstractRequestLoggingFilter.java
Let's say we whish skipping GET requests and only tracing write requests (PUT, PATCH, DELETE, etc) with INFO log level:
#Bean
public CommonsRequestLoggingFilter requestLoggingFilter() {
CommonsRequestLoggingFilter logFilter = new CommonsRequestLoggingFilter() {
#Override
protected boolean shouldLog(HttpServletRequest request) {
return logger.isInfoEnabled() && !Objects.equals(request.getMethod(), "GET");
}
#Override
protected void beforeRequest(HttpServletRequest request, String message) {
// Do nothing if you need logging payload.
// As, Before the Request, the payload is not read from the input-stream, yet.
}
#Override
protected void afterRequest(HttpServletRequest request, String message) {
logger.info(message); // Or log to a file here, as OP asks.
}
#Override
protected #NonNull String createMessage(HttpServletRequest request, #NonNull String prefix, #NonNull String suffix) {
// Output: [PUT][/api/my-entity], user:[my-loging], payload was:[{ "id": 33, "value": 777.00}]
StringBuilder msg = new StringBuilder()
.append(prefix)
.append("[").append(request.getMethod()).append("]")
.append("[").append(request.getRequestURI()).append("]");
String user = request.getRemoteUser();
msg.append(", user:[").append(null == user ? "" : user).append("]");
String payload = getMessagePayload(request);
if (payload != null) {
// It's not null on After event. As, on Before event, the Input stream was not read, yet.
msg.append(", payload was:[").append(payload.replace("\n", "")).append("]"); // Remove /n to be compliant with elastic search readers.
}
msg.append(suffix);
return msg.toString();
}
};
logFilter.setBeforeMessagePrefix("Incoming REST call: -->>>[");
logFilter.setBeforeMessageSuffix("]...");
logFilter.setAfterMessagePrefix("REST call processed: -<<<[");
logFilter.setAfterMessageSuffix("]");
logFilter.setIncludePayload(true);
logFilter.setMaxPayloadLength(64000);
return logFilter;
}
Loggging Requeest + Response/status:

(I can add the exact code example to here if the answer gets the demand/ reaches 50+ upvotes)

You can use Actuator in Spring Boot.
It logs requests and responses and more information about servlet and system operating.
You just add it as a dependency of your project and config, if more details needed to log.
Take a look at this example:

In order to log requests that result in 400 only:

Server Sent Event Client with additional Cookie

I am trying to unit test a Server Sent Event resource with an additional cookie. I am already using Jersey for the EventSource and JavaX for the client. The following code works fine:
WebTarget target = ClientBuilder.newBuilder()
.register(SseFeature.class)
.build()
.target("http://localhost:8080/sse");
EventSource eventSource = EventSource.target(target).build();
EventListener listener = new EventListener() {
#Override
public void onEvent(InboundEvent inboundEvent) {
LOG.info(inboundEvent.readData(String.class));
}
};
eventSource.register(listener);
eventSource.open();
serverEventManager.send("/sse", "foo");
eventSource.close();
Hoewever, for an additional unit test I need to add an additional cookie to the request. I have already tryed the following
target.(...).request.cookie("foo", "bar");
But this returns a builder from which I can't create the required WebTarget for the EventSource.

Here's what's happens within EventSource to establish a conection to the given WebTarget:
private Invocation.Builder prepareHandshakeRequest() {
Invocation.Builder request = EventSource.this.target
.request(new MediaType[] { SseFeature.SERVER_SENT_EVENTS_TYPE });
if ((this.lastEventId != null) && (!(this.lastEventId.isEmpty()))) {
request.header("Last-Event-ID", this.lastEventId);
}
if (EventSource.this.disableKeepAlive) {
request.header("Connection", "close");
}
return request;
}
As we can see - no chance to add a cookie here.
So WebTarget.request(new MediaType[] { SseFeature.SERVER_SENT_EVENTS_TYPE }) needs to return a Builder that
already has that desired cookie added.
Consider this delegating class adding the desired cookie to all request* type methods:
public class CookieAddedWebTarget implements WebTarget {
private WebTarget base;
private Cookie cookie;
public CookieAddedWebTarget(WebTarget base, Cookie cookie) {
this.base = base;
this.cookie = cookie;
}
// Inject that cookie whenever someone requests a Builder (like EventSource does):
public Builder request() {
return base.request().cookie(cookie);
}
public Builder request(String... paramArrayOfString) {
return base.request(paramArrayOfString).cookie(cookie);
}
public Builder request(MediaType... paramArrayOfMediaType) {
return base.request(paramArrayOfMediaType).cookie(cookie);
}
public Configuration getConfiguration() {
return base.getConfiguration();
}
//All other methods from WebTarget are delegated as-is:
public URI getUri() {
return base.getUri();
}
public UriBuilder getUriBuilder() {
return base.getUriBuilder();
}
public WebTarget path(String paramString) {
return base.path(paramString);
}
public WebTarget matrixParam(String paramString, Object... paramArrayOfObject) {
return base.matrixParam(paramString, paramArrayOfObject);
}
public WebTarget property(String paramString, Object paramObject) {
return base.property(paramString, paramObject);
}
public WebTarget queryParam(String paramString, Object... paramArrayOfObject) {
return base.queryParam(paramString, paramArrayOfObject);
}
public WebTarget register(Class<?> paramClass, Class<?>... paramArrayOfClass) {
return base.register(paramClass, paramArrayOfClass);
}
public WebTarget register(Class<?> paramClass, int paramInt) {
return base.register(paramClass, paramInt);
}
public WebTarget register(Class<?> paramClass, Map<Class<?>, Integer> paramMap) {
return base.register(paramClass, paramMap);
}
public WebTarget register(Class<?> paramClass) {
return base.register(paramClass);
}
public WebTarget register(Object paramObject, Class<?>... paramArrayOfClass) {
return base.register(paramObject, paramArrayOfClass);
}
public WebTarget register(Object paramObject, int paramInt) {
return base.register(paramObject, paramInt);
}
public WebTarget register(Object paramObject, Map<Class<?>, Integer> paramMap) {
return base.register(paramObject, paramMap);
}
public WebTarget register(Object paramObject) {
return base.register(paramObject);
}
public WebTarget resolveTemplate(String paramString, Object paramObject) {
return base.resolveTemplate(paramString, paramObject);
}
public WebTarget resolveTemplate(String paramString, Object paramObject, boolean paramBoolean) {
return base.resolveTemplate(paramString, paramObject, paramBoolean);
}
public WebTarget resolveTemplateFromEncoded(String paramString, Object paramObject) {
return base.resolveTemplateFromEncoded(paramString, paramObject);
}
public WebTarget resolveTemplates(Map<String, Object> paramMap) {
return base.resolveTemplates(paramMap);
}
public WebTarget resolveTemplates(Map<String, Object> paramMap, boolean paramBoolean) {
return base.resolveTemplates(paramMap, paramBoolean);
}
public WebTarget resolveTemplatesFromEncoded(Map<String, Object> paramMap) {
return base.resolveTemplatesFromEncoded(paramMap);
}
}
Now you should be able to reerite your test to:
EventSource eventSource = EventSource.target(new CookieAddedWebTarget(target,
new Cookie("name", "value"))).build();
And the cookie should be inserted.
Caveat: I have no way of testing this. Solution based only on reading source-code of jersey-media-sse-2.22.1.
Good Luck.

You could set the cookie in a ClientRequestFilter. Though the getCookies() on the ClientRequestContext is immutable, you should remember that a cookie is technically nothing more than a header. And the headers map on the request context is mutable. So you could do something like
public static class SseCookieFilter implements ClientRequestFilter {
#Override
public void filter(ClientRequestContext requestContext) throws IOException {
Cookie cookie = new Cookie("foo", "bar");
requestContext.getHeaders().add("Cookie", cookie.toString());
}
}
Just register the filter with the client (client.register(new SseCookieFilter())). It would be the same result as if you were to do
target.(...).request().cookie("foo", "bar");
Here is a complete example using Jersey Test Framework
public class SseCookieFilterTest extends JerseyTest {
#Path("events")
public static class SseResource {
#GET
#Produces(SseFeature.SERVER_SENT_EVENTS)
public EventOutput getServerSentEvents(#CookieParam("foo") String foo) {
final EventOutput eventOutput = new EventOutput();
new Thread(() -> {
try {
final OutboundEvent.Builder eventBuilder
= new OutboundEvent.Builder();
eventBuilder.name("message");
eventBuilder.data(String.class, "Blah " + foo + "!!!");
final OutboundEvent event = eventBuilder.build();
eventOutput.write(event);
} catch (IOException e) {
throw new RuntimeException(e);
} finally {
try {
eventOutput.close();
} catch (IOException ioClose) {
throw new RuntimeException(ioClose);
}
}
}).start();
return eventOutput;
}
}
public static class SseCookieFilter implements ClientRequestFilter {
#Override
public void filter(ClientRequestContext requestContext) throws IOException {
Cookie cookie = new Cookie("foo", "bar");
requestContext.getHeaders().add("Cookie", cookie.toString());
}
}
#Override
public ResourceConfig configure() {
return new ResourceConfig(SseResource.class)
.register(new LoggingFilter());
}
#Test
public void doit() throws Exception {
Client client = ClientBuilder.newBuilder()
.register(SseFeature.class).build();
client.register(new SseCookieFilter());
WebTarget target = client.target("http://localhost:9998/events");
EventSource eventSource = EventSource.target(target).build();
EventListener listener = (InboundEvent inboundEvent) -> {
System.out.println("From server ---====++++> "
+ inboundEvent.readData(String.class));
};
eventSource.register(listener, "message");
eventSource.open();
Thread.sleep(100);
eventSource.close();
}
}
These are the only dependencies needed to test
<dependency>

Not able to pass a primitive value to my custom SOAPHandler class

I have written custom soaphandler class which extends javax.xml.rpc.GenericHandler. And my requirement is to pass a primitive variable into this handler class from my other caller java class. This variable should pass at run time and should be thread safe because multiple thread is going to access that handler same time.
I tried to store the value into HandlerConfig object and injected it to the HandlerInfo, but I couldn't found this value in my handler.
This Soap Handler concept is new for me, so please help me to fix this issue.
below I'm posting my raw code for handler class and the class from where I'm calling it.
public class MilerHandler extends GenericHandler {
private HandlerInfo info;
private static final String AUTHORIZATION = "Authorization";
private static final String DATE = "Date";
private static final String URI = "http://-----.com";
public MilerHandler() {
}
public void init(HandlerInfo info) {
this.info = info;
}
public QName[] getHeaders() {
return info.getHeaders();
}
public boolean handleRequest(MessageContext context) {
SOAPMessageContext smc = (SOAPMessageContext)context;
SOAPMessage message = smc.getMessage();
try {
SOAPEnvelope envelope = smc.getMessage().getSOAPPart().getEnvelope();
SOAPFactory factory = SOAPFactory.newInstance();
SOAPElement authorization = factory.createElement(AUTHORIZATION, PCMilerClientService.PREFIX, URI);
SOAPElement date = factory.createElement(DATE, PCMilerClientService.PREFIX, URI);
authorization.addTextNode((String)value1); //Value1 need to be pass from my business class.
date.addTextNode((int)value2); //Value2 need to be pass from my business class.
SOAPElement authHeader = factory.createElement(PCMilerClientService.AUTH_HEADER, PCMilerClientService.PREFIX, URI);
authHeader.addChildElement(authorization);
authHeader.addChildElement(date);
SOAPHeader header = envelope.getHeader();
header.addChildElement(authHeader);
message.saveChanges();
if(log.debug()) {
log.debug(message);
}
}
catch (Exception ex) {
log.error(ex);
}
return true;
}
public boolean handleResponse(javax.xml.rpc.handler.MessageContext context) {
SOAPMessageContext smc = (SOAPMessageContext)context;
SOAPMessage message = smc.getMessage();
if(log.debug()) {
log.debug(message);
}
return true;
}
public boolean handleFault(javax.xml.rpc.handler.MessageContext context) {
SOAPMessageContext smc = (SOAPMessageContext)context;
SOAPMessage message = smc.getMessage();
if(log.debug()) {
log.debug(message);
}
return true;
}
}
public class MilerDistanceLookupWorker {
public void run() {
IService_Stub stub = null;
Service_Impl impl = null;
try {
impl = new Service_Impl();
setPCMilerHandler(impl);
stub = (IService_Stub) impl.getBasicHttpBinding_IService();
} catch (ServiceException e) {
-----------------
}
}
private void setMilerHandler(Service_Impl impl) {
HandlerInfo handlerInfo = new HandlerInfo();
handlerInfo.setHandlerClass(MilerHandler.class);
QName authHeader = new QName(NAMESPACE, AUTH_HEADER, PREFIX);
List<HandlerInfo> headerList = impl.getHandlerRegistry().getHandlerChain(authHeader);
headerList.add(handlerInfo);
impl.getHandlerRegistry().setHandlerChain(authHeader, headerList);
}
}

If you are trying to implement SOAP auth handler then you need to do something like this:
public class SOAPAuthenticationHandler implements SOAPHandler<SOAPMessageContext> {
private String username;
private String password;
public SOAPAuthenticationHandler (String username, String password) {
this.username = username;
this.password = password;
}
#Override
public boolean handleMessage(SOAPMessageContext smc) {
Boolean outboundProperty = (Boolean) smc.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
if (!outboundProperty) {
return outboundProperty;
}
try {
SOAPEnvelope envelope = smc.getMessage().getSOAPPart().getEnvelope();
SOAPHeader header = envelope.addHeader();
SOAPElement security = header.addChildElement("Security", "wsse", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd");
security.addNamespaceDeclaration("common", "some xmlns");
SOAPElement usernameToken = security.addChildElement("UsernameToken", "wsse");
usernameToken.addAttribute(new QName("xmlns:wsu"), "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd");
SOAPElement usernameElement = usernameToken.addChildElement("Username", "wsse");
usernameElement.addTextNode(username);
SOAPElement passwordElement = usernameToken.addChildElement("PasswordSaltedDigest", "common");
passwordElement.setAttribute("Type", "http://www.w3.org/2001/04/xmldsig-more#gostr341194");
passwordElement.addTextNode(password);
} catch (SOAPException | DOMException e) {
getLogger().error(e.getMessage());
}
return outboundProperty;

And after that you need to add this handler to port' HandlerChain:
List handlerChain = ((BindingProvider) port).getBinding().getHandlerChain();
if (handlerChain == null) {
handlerChain = new ArrayList();
}
handlerChain.add(new SOAPAuthenticationHandler(username, password));
((BindingProvider) port).getBinding().setHandlerChain(handlerChain);
