Spring JSON request getting 406 (not Acceptable)

Question

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:

GET http://localhost:8080/web/getTemperature/2 406 (Not Acceptable)

Headers:

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...

<dependency>
    <groupId>com.fasterxml.jackson.jaxrs</groupId>
    <artifactId>jackson-jaxrs-base</artifactId>
    <version>2.6.3</version>
</dependency>

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.

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

I was having the same problem because I was missing the @EnableMvc annotation. (All of my spring configuration is annotation based, the XML equivalent would be mvc:annotation-driven)

Answer 5

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

Answer 6

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
