I am getting 400 Http response when i am passing the invalid json format,
I would like to return the custom json message instead of this , can any one advise how to do in Spring 4.1 ?
Handling Execption using ControllerAdvice,but it is not working.
#ControllerAdvice
public class GlobalControllerExceptionHandler {
#ExceptionHandler({org.springframework.http.converter.HttpMessageNotReadableException.class})
#ResponseStatus(HttpStatus.BAD_REQUEST)
#ResponseBody
public String resolveException() {
return "error";
}
}
spring-config.xml is given below
<bean
class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">

Similar question like below link
Using Spring MVC, accepting POST requests with bad JSON leads to a default 400 error code server page being returned
You can attempt to map the exception this way. This code will return a 400 status, but you can change the return the same way as is the link you posted
#ExceptionHandler
#ResponseStatus(HttpStatus.BAD_REQUEST)
public void handleJsonMappingException(JsonMappingException ex) {}
Finally i have handle the exception via Servlet Filter with HttpServletRequestWrapper.
Step 1: Add the filter
Step 2: Get the request body from Customize HttpServletRequestWrapper class
Step 3: Convert request body json string to java object using JSON API
Step 4: Chain the request/response
Step 5: Catch exception / and update the HttpServlet Response
Using below reference.
Filter Example
HttpServletRequestWrapper Example
String to Json Object
With the help of this approach i can handle 400/405/415 Http Errors.
You may try this, in your pom.xml add dependency:
<!-- Need this for json to/from object -->
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.6.3</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.6.3</version>
</dependency>
this will convert your java objects to JSON automatically when you return them. like you can write a class for response:
public class Response {
private int responseCode;
private String responseMessage;
//as many fields as you like
public Response (int responseCode, String responseMessage) {
this.responseCode = responseCode;
this.responseMessage = responseMessage;
} }
then you can return any java objects and they will be received as JSON,
#RequestMapping(value="/someMethod", method=RequestMethod.POST)
public #ResponseBody Response someMethod(#RequestBody Parameters param) {
return new Response(404, "your error message");
}
I m trying to create my first Spring application which is a simple REST webservice.
I want to make EVERY responses to be JSON (in the header) and I dont know how to make it in ONE time, I mean not in all my controller methods, like a config files or something else.
This is my code :
#RestController
public class HomeController {
#RequestMapping(value = "/something/{nom}/{id}", method = RequestMethod.GET)
public User hi(#PathVariable long id, #PathVariable String nom) {
return new User(id, nom);
}
}
Thanks for advance
Your method is correct. Since you are using Spring 4 and the annotation #RestController there's no need of using #ResponseBody.
In case you are not getting a JSON as return, please check if you have included Jackson Mapper dependency in your project.
You can do that by adding this on your pom.xml (presuming you are using Maven):
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-mapper-asl</artifactId>
<version>1.9.13</version>
</dependency>
By adding this dependency, Spring will be able to parse your object properly.
I am using Spring MVC and Security and I have a controller with 2 methods. One creates a webpage html, and on that will take that and make a PDF out of it.
#RequestMapping(value = "/getPDFhtml", method = RequestMethod.GET)
public ModelAndView getPDFhtml(HttpServletRequest request) throws Exception {
ModelAndView modelAndView = new ModelAndView("myPDFTemplate");
// do stuff
return modelAndView;
}
#RequestMapping(value = "/createPDFFile", method = RequestMethod.GET)
public ModelAndView createPDFFile(HttpServletRequest request) {
String url = "/getPDFHtml";
String viewHtml = HttpUtil.getHttpRequest(url);
// take viewHtml and turn it into a PDF with iText
// other stuff...
}
The only way I could get this to work was to punch a hole in spring security like this (security-app-context.xml)
<intercept-url pattern="/getPDFhtml/**" access="IS_AUTHENTICATED_ANONYMOUSLY" />
because tenically, my HttpUtil call is a new sesion. (It is just a wrapper for Apache HttpClitent.jar stuff)
Now I need to not do this. I need access to the AuthenticationTolken in getPDFhtml() and it's not there because it's authenticated ananymousy, and my manager found out about my little sceuity hack and it has to go away now. :(
so I need a way to either:
be able to call getPDFhtml() from createPDFFile() and have the ModelAndView render itself into an html string. (I was told 6 months ago that this is not possable, but who knows)
be able to call getPDFhtml() from createPDFFile() and somehow pass the jsession id or the authentication token or whatever so I can get through the Spring securuity properly.
any ideas?
I went with FreeMarker.
in my main-servlet.xml I create my freemarker config:
<bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
<property name="templateLoaderPath"><value>/WEB-INF/freemarker/</value></property>
</bean>
#Autowired it into my controller and easy:
Template template = freemarkerConfig.getConfiguration().getTemplate("helloWorld.ftl");
template.process(data, out);
String viewHtml = out.toString();
and off to iText it goes! Thanks for all the help.
I'm trying to return a JSON response with Spring 3.0.6, but I get a 406 response "Not Acceptable", with the description:
"The resource identified by this request is only capable of generating responses with characteristics
not acceptable according to the request "accept" headers ()."
I know that a very similar question has been asked before, but I can't make it work for my project, despite many
tests and I don't understand what I'm doing wrong.
In my Maven pom.xml I've the following:
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-mapper-asl</artifactId>
<version>1.8.5</version>
<scope>compile</scope>
</dependency>
<dependency>

In web.xml I reference webmvc-config.xml, and the log confirms that is loaded.
<servlet>
<servlet-name>mainServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/webmvc-config.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
In webmvc-config.xml I've the following:
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
<mvc:annotation-driven />
My Controller is:
#Controller
public class ClassifiedController {
#RequestMapping(value = "/classified/{idClassified}", headers = "Accept=*/*",
method = RequestMethod.GET)
#ResponseBody
public final Classified getClassified(#PathVariable final int idClassified) {
...
I tried with or without the headers parameter with the same results. If I call the URL
directly with Firefox the Request Headers contain the following (checked with firebug):
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
If I use the following JQuery:
$.ajax({
url: '/classified/38001',
type: 'GET',
dataType: 'json'
});
The following headers are sent:
Accept: application/json, text/javascript, */*; q=0.01
In both cases the result is a 406 error. I don't know what else should I check to make
it work.
UPDATE: I decided to debug through Spring and I found out that Jackson was called correctly and in org.codehaus.jackson.map.ser.StdSerializerProvider the method _findExplicitUntypedSerializer contains the following code:
try {
return _createAndCacheUntypedSerializer(runtimeType, property);
} catch (Exception e) {
return null;
}
This is unfortunate because hides the source of the problem. With the debugger I found out that that exception contained a very descriptive error message:
Conflicting getter definitions for property "reminded":
ClassifiedImpl#isReminded(0 params) vs
ClassifiedImpl#getReminded(0 params)
Now that I see the error message is a silly mistake and easy to fix, but without that it wasn't that obvious. In fact, fixing the problem, leaded to a working serialization.
Add the following in DispatcherServlet-servlet.xml.
<bean id="jacksonMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"></bean>
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="messageConverters">
<list>
<ref bean="jacksonMessageConverter"/>
</list>
</property>
</bean>
I've stumbled upon the same error (406: content not acceptable) with Spring MVC and #RestController annotation.
The Spring handler:
#RequestMapping(value = "/stuff-acknowledgment/{id}", produces ="application/json;charset=UTF-8", headers="Accept=*")
public Message acknowledgeStuff(#PathVariable("id") String id, #ModelAttribute("ack") AckBean acquittement) {
Observation:
the URI has the form : http://www.host.com/stuff-acknowledgment/{id}
BUT $id has a very particular format: xxxcomplicatedhashxxx.png (or whatever extension you can think of).
Therefore:
Spring MVC interpret the extension and want to produce a result of that same mime type (even if I define it as a path variable), here an "image/png" MIME type even if I tell him to produce JSON. So a 406 exception is thrown.
Fix:
Remove the ".png" extension in the URI, or remove the PathVariable and put it in the body, or add a suffix behind the pathVariable (not tested but should work as well), the point is to avoid a file extension at the end of the URI.
P.S.: I know it doesn't answer the specific problem (with the solution in the update) in the question but I found that SO thread when searching for that problem and post my fix here for the record, hoping it can help someone in the future.
In terms of the MappingJacksonJson processing, you'll need to make sure that the Jackson ObjectMapper supports your object type for serialisation.
I ran into this problem because the objects that I wanted to return as JSON didn't have any getter methods for their properties. Jackson probably needs these. After adding them it worked.
although this thread is a little old...
u need to add the following (maven dependency):
org.codehaus.jacksonjackson-mapper-asl1.9.13
this is my javascript:
function getWeather() {
$.getJSON('getTemperature/' + $('.data option:selected').val(), null, function(data) {
alert('Success');
});
}
this is my controller:
#RequestMapping(value="/getTemperature/{id}", headers="Accept=*/*", method = RequestMethod.GET)
#ResponseBody
public Weather getTemparature(#PathVariable("id") Integer id){
Weather weather = weatherService.getCurrentWeather(id);
return weather;
}
spring-servlet.xml
<context:annotation-config />
<tx:annotation-driven />
Getting this error:

Interesting note:
I get 406 error, but the hibernate query works meanwhile.
This is what tomcat log says, everytime when I change selection in dropbox:
select weather0_.ID as ID0_0_, weather0_.CITY_ID as CITY2_0_0_, weather0_.DATE as DATE0_0_, weather0_.TEMP as TEMP0_0_ from WEATHER weather0_ where weather0_.ID=?
What could the problem be? There were two similar questions in SO before, I tried all the accepted hints there, but they did not work I guess...
Any suggestions? Feel free to ask questions...
406 Not Acceptable
The resource identified by the request is only capable of generating response entities which have content characteristics not acceptable according to the accept headers sent in the request.
So, your request accept header is application/json and your controller is not able to return that. This happens when the correct HTTPMessageConverter can not be found to satisfy the #ResponseBody annotated return value. HTTPMessageConverter are automatically registered when you use the <mvc:annotation-driven>, given certain 3-d party libraries in the classpath.
Either you don't have the correct Jackson library in your classpath, or you haven't used the
<mvc:annotation-driven> directive.
I successfully replicated your scenario and it worked fine using these two libraries and no headers="Accept=*/*" directive.
jackson-core-asl-1.7.4.jar
jackson-mapper-asl-1.7.4.jar
I had same issue, with Latest Spring 4.1.1 onwards you need to add following jars to pom.xml.
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.4.1</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.4.1.1</version>
</dependency>
also make sure you have following jar:
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-core-asl</artifactId>
<version>1.9.13</version>
</dependency>
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-mapper-asl</artifactId>
<version>1.9.13</version>
</dependency>
406 Spring MVC Json, not acceptable according to the request "accept" headers
There is another case where this status will be returned: if the Jackson mapper cannot figure out how to serialize your bean. For example, if you have two accessor methods for the same boolean property, isFoo() and getFoo().
What's happening is that Spring's MappingJackson2HttpMessageConverter calls Jackson's StdSerializerProvider to see if it can convert your object. At the bottom of the call chain, StdSerializerProvider._createAndCacheUntypedSerializer throws a JsonMappingException with an informative message. However, this exception is swallowed by StdSerializerProvider._createAndCacheUntypedSerializer, which tells Spring that it can't convert the object. Having run out of converters, Spring reports that it's not being given an Accept header that it can use, which of course is bogus when you're giving it */*.
There is a bug for this behavior, but it was closed as "cannot reproduce": the method that's being called doesn't declare that it can throw, so swallowing exceptions is apparently an appropriate solution (yes, that was sarcasm). Unfortunately, Jackson doesn't have any logging ... and there are a lot of comments in the codebase wishing it did, so I suspect this isn't the only hidden gotcha.
I had the same problem, my controller method executes but response is Error 406.
I debug AbstractMessageConverterMethodProcessor#writeWithMessageConverters and found that method ContentNegotiationManager#resolveMediaTypes always returns text/html which is not supported by MappingJacksonHttpMessageConverter. The problem is that the org.springframework.web.accept.ServletPathExtensionContentNegotiationStrategy works earlier than org.springframework.web.accept.HeaderContentNegotiationStrategy, and extension of my request /get-clients.html is the cause of my problem with Error 406. I just changed request url to /get-clients.
Make sure that the sent object (Weather in this case) contains getter/setter
Make sure that following 2 jar's are present in class path.
If any one or both are missing then this error will come.
jackson-core-asl-1.9.X.jar jackson-mapper-asl-1.9.X.jar
Finally found answer from here:
Mapping restful ajax requests to spring
I quote:
#RequestBody/#ResponseBody annotations don't use normal view resolvers, they use their own HttpMessageConverters. In order to use these annotations, you should configure these converters in AnnotationMethodHandlerAdapter, as described in the reference (you probably need MappingJacksonHttpMessageConverter).
Check <mvc:annotation-driven /> in dispatcherservlet.xml , if not add it.
And add
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-core-asl</artifactId>
<version>1.9.13</version>
</dependency>
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-mapper-asl</artifactId>
<version>1.9.13</version>
</dependency>
these dependencies in your pom.xml
Probably no one is scrolling down this far, but none of the above solutions fixed it for me, but making all my getter methods public did.
I'd left my getter visibility at package-private; Jackson decided it couldn't find them and blew up. (Using #JsonAutoDetect(getterVisibility=NON_PRIVATE) only partially fixed it.
<dependency>
<groupId>com.fasterxml.jackson.jaxrs</groupId>
<artifactId>jackson-jaxrs-base</artifactId>
<version>2.6.3</version>
</dependency>
I was having the same problem because I was missing the #EnableWebMvc annotation. (All of my spring configurations are annotation-based, the XML equivalent would be mvc:annotation-driven)
In the controller, shouldn't the response body annotation be on the return type and not the method, like so :
#RequestMapping(value="/getTemperature/{id}", headers="Accept=*/*", method = RequestMethod.GET)
public #ResponseBody Weather getTemparature(#PathVariable("id") Integer id){
Weather weather = weatherService.getCurrentWeather(id);
return weather;
}
I'd also use the raw jquery.ajax function, and make sure contentType and dataType are being set correctly.
On a different note, I find the spring handling of json rather problematic. It was easier when I did it all myself using strings, and GSON.
As #atott mentioned.
If you have added the latest version of Jackson in your pom.xml, and with Spring 4.0 or newer, using #ResponseBody on your action method and #RequestMapping configured with produces="application/json;charset=utf-8", however, you still got 406(Not Acceptable), I guess you need to try this in your MVC DispatcherServlet context configuration:
<mvc:annotation-driven content-negotiation-manager="contentNegotiationManager" />
<bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
<property name="favorPathExtension" value="false" />
</bean>
That's the way how I resolved my issue finally.
check this thread.
spring mvc restcontroller return json string
p/s: you should add jack son mapping config to your WebMvcConfig class
#Override
protected void configureMessageConverters(
List<HttpMessageConverter<?>> converters) {
// put the jackson converter to the front of the list so that application/json content-type strings will be treated as JSON
converters.add(new MappingJackson2HttpMessageConverter());
// and probably needs a string converter too for text/plain content-type strings to be properly handled
converters.add(new StringHttpMessageConverter());
}
Spring 4.3.10: I used the below settings to resolve the issue.
Step 1: Add the below dependencies
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.6.7</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.6.7</version>
</dependency>
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-core-asl</artifactId>
<version>1.9.13</version>
</dependency>
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-mapper-asl</artifactId>
<version>1.9.13</version>
</dependency>
Step 2: Add the below in your MVC DispatcherServlet context configuration:
<mvc:annotation-driven content-negotiation-manager="contentNegotiationManager"/>
<bean id="contentNegotiationManager"
class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
<property name="favorPathExtension" value="false"/>
<property name="favorParameter" value="true"/>
<property name="ignoreAcceptHeader" value="false" />
</bean>
Since spring 3.2, as per the default configuration favorPathExtension is set as true, because of this if the request uri have any proper extensions like .htm spring will give priority for the extension. In step 2 I had added the contentNegotiationManager bean to override this.
make sure your have correct jackson version in your classpath
Check as #joyfun did for the correct version of jackson but also check our headers ... Accept / may not be transmitted by the client ... use firebug or equivalent to check what your get request is actually sending. I think the headers attribute of the annotation /may/ be checking literals although I'm not 100% sure.
Other then the obvious problems I had another one that I couldn't fix regardless of including all possible JARs, dependancies and annotations in Spring servlet. Eventually I found that I have wrong file extension by that I mean I had two separate servlet running in same container and I needed to map to different file extensions where one was ".do" and the other as used for subscriptions was randomly named ".sub". All good but SUB is valid file extension normally used for films subtitle files and thus Tomcat was overriding the header and returning something like "text/x-dvd.sub..." so all was fine but the application was expecting JSON but getting Subtitles thus all I had to do is change the mapping in my web.xml file I've added:
<mime-mapping>
<extension>sub</extension>
<mime-type>application/json</mime-type>
</mime-mapping>
I had the same problem unfortunately non of the solution here solved my problem as my problem was something in a different class.
I first checked that all dependencies are in place as suggested by #bekur
then I checked the request/response that travels from clients to the server all headers was in place an properly set by Jquery.
I then checked the RequestMappingHandlerAdapter MessageConverters and all 7 of them were in place, I really started to hate Spring ! I then updated to from Spring 4.0.6.RELEASE to 4.2.0.RELEASE I have got another response rather than the above. It was Request processing failed; nested exception is java.lang.IllegalArgumentException: No converter found for return value of type
Here is my controller method
#RequestMapping(value = "/upload", method = RequestMethod.POST,produces = "application/json")
public ResponseEntity<UploadPictureResult> pictureUpload(FirewalledRequest initialRequest) {
DefaultMultipartHttpServletRequest request = (DefaultMultipartHttpServletRequest) initialRequest.getRequest();
try {
Iterator<String> iterator = request.getFileNames();
while (iterator.hasNext()) {
MultipartFile file = request.getFile(iterator.next());
session.save(toImage(file));
}
} catch (Exception e) {
return new ResponseEntity<UploadPictureResult>(new UploadPictureResult(),HttpStatus.INTERNAL_SERVER_ERROR);
}
return new ResponseEntity<UploadPictureResult>(new UploadPictureResult(), HttpStatus.OK);
}
public class UploadPictureResult extends WebResponse{
private List<Image> images;
public void setImages(List<Image> images) {
this.images = images;
}
}
public class WebResponse implements Serializable {
protected String message;
public WebResponse() {
}
public WebResponse(String message) {
this.message = message;
}
public void setMessage(String message) {
this.message = message;
}
}
The solution was to make UploadPictureResult not to extend WebResponse
For some reason spring was not able to determine the how to convert UploadPictureReslt when it extended WebResponse
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.8.0</version>
</dependency>
i don't use ssl authentication and this jackson-databind contain jackson-core.jar and jackson-databind.jar, and then change the RequestMapping content like this:
#RequestMapping(value = "/id/{number}", produces = "application/json; charset=UTF-8", method = RequestMethod.GET)
public #ResponseBody Customer findCustomer(#PathVariable int number){
Customer result = customerService.findById(number);
return result;
}
attention:
if your produces is not "application/json" type and i had not noticed this and got an 406 error, help this can help you out.
This is update answer for springVersion=5.0.3.RELEASE.
Those above answers will be only worked older springVersion < 4.1 version. for latest spring you have to add following dependencies in gradle file:
compile group: 'com.fasterxml.jackson.core', name: 'jackson-core', version: fasterxmljackson
compile group: 'com.fasterxml.jackson.core', name: 'jackson-databind', version: fasterxmljackson
fasterxmljackson=2.9.4
I hope this will be helpful for who using latest spring version.
Simple answer just add Getter method in your domain/model class.
But Why this works ??
Under the hood Spring used HttpMessageConverters to convert your input JSON to Java Object. The Accept header that is passed in the request is used to select appropriate MessageConvertor at runtime. These message convertors use getter of your domain/model class for conversion, so if there are no getter method, Marshall and unmarshall Java Objects to and from JSON will not happen, even if you add Jackson in your classpath, because even Jackson lib uses Getter methods for marshalling stuffs !!.
Can you remove the headers element in #RequestMapping and try..
Like
#RequestMapping(value="/getTemperature/{id}", method = RequestMethod.GET)
I guess spring does an 'contains check' rather than exact match for accept headers. But still, worth a try to remove the headers element and check.
