Springboot how to validate token on Zuul microservice

I am new to Springboot and im trying to filter requests through a Zuul API gateway however i get the error below :
AnonymousAuthenticationToken cannot be cast to org.aacctt.ms.auth.security.JWTAuthentication
When i put a breakpoint i get a null header/token string value when the request reaches the authentication service from zuul gateway, this happens for protected requests that require an authorization token.
My aim is to be able to verify the token sent by clients so that i can allow the client's request to protected endpoints or reject it.
Im not sure what im doing wrong here is my code:

The issue is the sensitive header, Authorization is sensitive header by default in Zuul, you just need to override the sensitive headers.
zuul:
sensitive-headers:
-
By setting this property in Zuul gateway application.yml it route request to auth service with the Authorization header

Spring Boot Raw WebSocket Set Principal

I want to develop notification sender in real time with Spring Boot but I can't use Stomp and sockjs, so I need implement raw WebSocket but I can't find out how to set Principal in WebSocket connection beacuse I want to Authenticate with JWT token. So, where or how can I set principal.
I'am using these;
WebSocketConfig.java :
#EnableWebSocket
#Configuration
public class WebSocketConfig implements WebSocketConfigurer {
#Autowired
WebSocketNotificationSenderService senderService;
#Override
public void registerWebSocketHandlers(WebSocketHandlerRegistry
webSocketHandlerRegistry) {
webSocketHandlerRegistry.addHandler(createHandler(),
"/handler").addInterceptors(new HttpSessionHandshakeInterceptor()
{
#Override
public void afterHandshake(ServerHttpRequest request,
ServerHttpResponse response, WebSocketHandler wsHandler,
#Nullable Exception ex) {
super.afterHandshake(request, response, wsHandler, ex);
}
#Override
public boolean beforeHandshake(ServerHttpRequest request,
ServerHttpResponse response, WebSocketHandler wsHandler,
Map<String, Object> attributes) throws Exception {
return super.beforeHandshake(request, response,
wsHandler, attributes)
}
});
}
#Bean
public WebSocketHandler createHandler() {
return new MyHandler(senderService);
}
}
MyHandler.java :
#Component
public class MyHandler extends TextWebSocketHandler {
WebSocketNotificationSenderService senderService;
public MyHandler(WebSocketNotificationSenderService senderService){
this.senderService = senderService;
}
#Override
public void afterConnectionEstablished(WebSocketSession session) throws Exception {
senderService.addToSession(session);
}
}
WebSocketNotificationSenderService.java :
#Service
public class WebSocketNotificationSenderService implements
IWebSocketSenderService<WrapperWsNotification> {
private List<WebSocketSession> sessions = new CopyOnWriteArrayList<>();
private ObjectMapper mapper = new ObjectMapper();
public void addToSession(WebSocketSession session) {
sessions.add(session);
}
#Override
public void convertAndSend(WrapperWsNotification payload) throws JsonProcessingException {
String payloadString = mapper.writeValueAsString(payload);
sessions.stream().forEach(session -> {
try {
session.sendMessage(new TextMessage(payloadString));
} catch (IOException e) {
e.printStackTrace();
}
});
}
#Override
public void convertAndSendToUser(String user, WrapperWsNotification payload) throws
JsonProcessingException {
String payloadString = mapper.writeValueAsString(payload);
sessions.forEach(session -> {
if (session.getPrincipal().getName().equals(user)) {
try {
session.sendMessage(new TextMessage(payloadString));
} catch (IOException e) {
e.printStackTrace();
}
}
});
}
}
My Notification Sender to websocket;
#Component
public class NotificationConsumer {
#Autowired
WebSocketNotificationSenderService webSocket;
private Logger logger = LoggerFactory.getLogger(NotificationConsumer.class);
public void onReceiveNotification(String object) throws IOException {
ObjectMapper objectMapper = new ObjectMapper();
WrapperWsNotification wrapperWsNotification= objectMapper.readValue(object, WrapperWsNotification.class);
logger.info("User where coming from redis " + wrapperWsNotification.getUser().getUsername());
webSocket.convertAndSendToUser(wrapperWsNotification.getUser().getUsername(), wrapperWsNotification);
}
}

I find out solution and added an example

JWT authentication without database access

I am new to JWT. I create my own microservice and want to introduce JWT authentication. I have one website that issues a token and in the other I want to check the correctness of this token. I want to do this without connecting the second site to db. This approach seems to me appropriate and best for user data.
I have following payload of token:
{
"sub": "Marek",
"auth": [
{
"authority": "ROLE_USER"
}
],
"iat": 1574091010,
"exp": 1574091210
}
Its my code:
WebSecurityConfig
#Autowired
private JwtTockenCreator jwtTockenCreator;

http.csrf().disable();
http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);

.antMatchers("/user/addUser").permitAll()
.anyRequest()
.authenticated();
http.exceptionHandling().accessDeniedPage("/login");
http.apply(new JWTConfigurer(jwtTockenCreator));
}
#Override

}
#Bean

return super.authenticationManagerBean();
}

}
} catch (CustomException ex) {
// this is very important, since it guarantees the user is not authenticated at

String token = restTemplate.postForObject(urlUser, user, String.class);
return ResponseEntity.ok(token);
}
}
In Eclipse doesn't give any errors. That's why I don't know what I'm doing wrong
when I want to call / user / addUser and add a new user nothing happens. In the User service I call, I have a function responsible for adding users and it works correctly when I refer to it directly. And if I want to do it through my Rest Api it doesn't work anymore. And it is my problem that I do not know what can happen because I have no mistake. I remind you that I am still learning and I am asking for understanding

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.

Spring security- Send credentials as json instead of regular form in rest service

I am writing rest service with json. For backend I use Spring Security. I have form witch sends with ajax rest object as follow:
{email: "admin", password: "secret"}
Now on the server I have configuration as follow:
#Configuration
#EnableWebSecurity
#ComponentScan("pl.korbeldaniel.cms.server")
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
private RestAuthenticationEntryPoint restAuthenticationEntryPoint;
#Autowired
private RestAuthenticationSuccessHandler authenticationSuccessHandler;
#Autowired
private RestAuthenticationFailureHandler authenticationFailureHandler;
#Bean
JsonAuthenticationFilter jsonAuthenticationFilter() throws Exception {
JsonAuthenticationFilter filter = new JsonAuthenticationFilter();
filter.setAuthenticationManager(authenticationManagerBean());
System.out.println("jsonAuthenticationFilter");
return filter;
}
#Bean
public RestAuthenticationSuccessHandler mySuccessHandler() {
return new RestAuthenticationSuccessHandler();
}
#Override
#Autowired
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication().withUser("admin").password("secret").roles("ADMIN");
// auth.jdbcAuthentication().
}
#Override
protected void configure(HttpSecurity http) throws Exception {
http.addFilterBefore(jsonAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class);
http.csrf().disable();//
http.exceptionHandling().authenticationEntryPoint(restAuthenticationEntryPoint)//
.and().authorizeRequests()//
.antMatchers("/").permitAll()//
.antMatchers("/services/anonymous/**").permitAll()//
.antMatchers("/services/authenticated/**").authenticated()//
.and().formLogin().loginProcessingUrl("/services/anonymous/loginService/login").usernameParameter("email").passwordParameter("password")//
.successHandler(authenticationSuccessHandler)//
.and().logout().logoutUrl("/services/anonymous/loginService/logout");
// http.httpBasic();
}
}
Problem is that spring security demands from me to send credentials as body, but I would like to spring accept my Json object.
So I've wrote my own authentication filter base on this:
#Component
public class JsonAuthenticationFilter extends UsernamePasswordAuthenticationFilter {
private boolean postOnly;
#Override
public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException {
System.out.println("attemptAuthentication");
if (postOnly && !request.getMethod().equals("POST")) {
throw new AuthenticationServiceException("Authentication method not supported: " + request.getMethod());
}
UsernamePasswordAuthenticationToken authRequest = this.getUserNamePasswordAuthenticationToken(request);
// Allow subclasses to set the "details" property
setDetails(request, authRequest);
return this.getAuthenticationManager().authenticate(authRequest);
}
/**
* #param request
* #return
*/
private UsernamePasswordAuthenticationToken getUserNamePasswordAuthenticationToken(HttpServletRequest request) {
// TODO Auto-generated method stub
System.out.println(request);
return null;
}
}
But unfortunatelly this filter seems to not work.
When I send ajax post request from login form, I am getting 302 Found and then I am getting this:
Remote Address:127.0.0.1:8080
Request URL:http://localhost:8080/cms/login?error
Request Method:GET
Status Code:404 Not Found
Like there fail to validate user credential (cause form body is empty and credentials goes as json), and then it redirect to login?error which doesn't exist cause I've my own login form.
Please help.
Edit
public class WebServletInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
#Override
protected Class<?>[] getRootConfigClasses() {
return new Class<?>[] { SecurityConfig.class };
}
#Override
protected Class<?>[] getServletConfigClasses() {
return new Class<?>[] { WebConfig.class };
}
#Override

}
}
#EnableWebMvc
#ComponentScan(basePackages = "pl.daniel.cms.server")
public class WebConfig extends WebMvcConfigurerAdapter {
}

Well, it must not work until you write the getUserNamePasswordAuthenticationToken body.
Actually, you must read the request body of the HttpServletRequest, parse it through Jackson or any other mapping way and create with it the UsernamePasswordAuthenticationToken.
Using Jackson (choose the right version depending on your Spring version), I would create a simple bean like this:
#JsonIgnoreProperties(ignoreUnkown=true)
public LoginRequest{
private String email;
private String password;
// getters & setters
}
The use it to map it the request body:
private UsernamePasswordAuthenticationToken getUserNamePasswordAuthenticationToken(HttpServletRequest request) throws IOException{
StringBuffer sb = new StringBuffer();
BufferedReader bufferedReader = null;
String content = "";
LoginRequest sr = null;
try {
bufferedReader = request.getReader()
char[] charBuffer = new char[128];
int bytesRead;
while ( (bytesRead = bufferedReader.read(charBuffer)) != -1 ) {
sb.append(charBuffer, 0, bytesRead);
}
content = sb.toString();
ObjectMapper objectMapper = new ObjectMapper();
try{
sr = objectMapper.readValue(content, LoginRequest.class);
}catch(Throwable t){
throw new IOException(t.getMessage(), t);
}
} catch (IOException ex) {
throw ex;
} finally {
if (bufferedReader != null) {
try {
bufferedReader.close();
} catch (IOException ex) {
throw ex;
}
}
}
return new UsernamePasswordAuthenticationToken(sr.getEmail(), sr.getPassword());
}
P.D. Yo must use Post, you will never be able to post a request-body using GET

You can extend and override WebSecurityConfigurerAdapter
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.csrf().disable()
.addFilter(new UserNamePasswordAuthFilter(authenticationManager(), userRepo))
.authorizeRequests()
.antMatchers("/login").permitAll()
.anyRequest()
.authenticated()
.and()
.httpBasic();
}
#Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(daoAuthenticationProvider());
}
#Bean
public DaoAuthenticationProvider daoAuthenticationProvider() {
DaoAuthenticationProvider provider = new DaoAuthenticationProvider();
provider.setUserDetailsService(userDetailsService); // custom user service
provider.setPasswordEncoder(passwordEncoder); // custom password encoder
return provider;
}
Then you can define a filter for authentication and optionally you can override successful login behavior.
public class UserNamePasswordAuthFilter extends UsernamePasswordAuthenticationFilter {
private final AuthenticationManager authManager;
private final AecUserRepo userRepo;
public UserNamePasswordAuthFilter(AuthenticationManager authManager, AecUserRepo userRepo) {
super();
this.authManager = authManager;
this.userRepo = userRepo;
}
#Override
public Authentication attemptAuthentication(HttpServletRequest request,
HttpServletResponse response) throws AuthenticationException {
try {
// Get username & password from request (JSON) any way you like
UsernamePassword authRequest = new ObjectMapper()
.readValue(request.getInputStream(), UsernamePassword.class);
Authentication auth = new UsernamePasswordAuthenticationToken(authRequest.getUsername(),
authRequest.getPassword());
return authManager.authenticate(auth);
} catch (Exception exp) {
throw new RuntimeException(exp);
}
}
#Override
protected void successfulAuthentication(HttpServletRequest request,
HttpServletResponse response, FilterChain chain, Authentication authResult)
throws IOException, ServletException {
if (logger.isDebugEnabled()) {
logger.debug("Authentication success. Updating SecurityContextHolder to contain: "
+ authResult);
}
// custom code
SecurityContextHolder.getContext().setAuthentication(authResult);
}
}
