Ajax Call:

$.ajax({ 
                        url: "/BusinessReimbursment/addDepartment", 
                        method: 'POST', 
                        dataType: 'json', 
                        data: "{\"message\":\"abc\",\"success\":true}",
                        contentType: 'application/json',
                        mimeType: 'application/json',
                        success: function(data) { 
                            alert(data.id + " " + data.name);
                            commit(true);
                        },
                        error:function(data,status,er) { 
                            alert("error: "+data+" status: "+status+" er:"+er);
                        }
                    });

Controller:

@RestController
public class DepartmentController {

    @Autowired 
    @Qualifier("departmentService")
    private DepartmentService departmentService;

    @RequestMapping(value="/addDepartment", method={RequestMethod.POST})
    public @ResponseBody AjaxResponse addDepartment(@RequestBody AjaxResponse  departmentDTO){
        AjaxResponse response=new AjaxResponse();
        return response;
    }

AppConfig.java

@Bean

public RequestMappingHandlerAdapter  annotationMethodHandlerAdapter()
{
    final RequestMappingHandlerAdapter annotationMethodHandlerAdapter = new RequestMappingHandlerAdapter();
    final MappingJackson2HttpMessageConverter mappingJacksonHttpMessageConverter = new MappingJackson2HttpMessageConverter();

    List<HttpMessageConverter<?>> httpMessageConverter = new ArrayList<HttpMessageConverter<?>>();
    httpMessageConverter.add(mappingJacksonHttpMessageConverter);

    String[] supportedHttpMethods = { "POST", "GET", "HEAD" };

    annotationMethodHandlerAdapter.setMessageConverters(httpMessageConverter);
    annotationMethodHandlerAdapter.setSupportedMethods(supportedHttpMethods);

    return annotationMethodHandlerAdapter;
}

please help me to get out out of that. I m using Spring 4, jakson 2.3.0

If i try to POST request it gives:org.springframework.web.HttpRequestMethodNotSupportedException: Request method 'POST' not supported

In my side, it is because POSTMAN setting issue, but I don't know why, maybe I copy a query from other. I simply create a new request in POSTMAN and run it, it works.

If it's working from Postman, try new Spring version, becouse the 'org.springframework.boot' 2.2.2.RELEASE version can throw "Required request body content is missing" exception.
Try 2.2.6.RELEASE version.

You shouldn't send a request body with an HTTP GET request. You should modify addDepartment() so that it only supports POST, and POST your JSON to that endpoint. If you want to GET information about a department, you should create a separate controller method that does that (and does not require a request body).

Also, double-check your endpoint definitions since you have misspelled "reimbursement" in the $.ajax call.

Try this:

@RequestBody(required = false) String str

I also had the same problem. I use "Postman" for JSON request. The code itself is not wrong. I simply set the content type to JSON (application/json) and it worked, as you can see on the image below

Sorry guys.. actually because of a csrf token was needed I was getting that issue. I have implemented spring security and csrf is enable. And through ajax call I need to pass the csrf token.

I made some minor modification to you code and tested it with a spring project that I have and it works, The logic will only work with POST if I use GET it throws an error with invalid request. Also in your ajax call I commented out commit(true), the browser debugger flagged and error that it is not defined. Just modify the url to fit your Spring project architecture. 

 $.ajax({ 
                    url: "/addDepartment", 
                    method: 'POST', 
                    dataType: 'json', 
                    data: "{\"message\":\"abc\",\"success\":true}",
                    contentType: 'application/json',
                    mimeType: 'application/json',
                    success: function(data) { 
                        alert(data.success + " " + data.message);
                        //commit(true);
                    },
                    error:function(data,status,er) { 
                        alert("error: "+data+" status: "+status+" er:"+er);
                    }
                });



@RequestMapping(value="/addDepartment", method=RequestMethod.POST)
  public AjaxResponse addDepartment(@RequestBody final AjaxResponse  departmentDTO)
  {
    System.out.println("addDepartment: >>>>>>> "+departmentDTO);
    AjaxResponse response=new AjaxResponse();
    response.setSuccess(departmentDTO.isSuccess());
    response.setMessage(departmentDTO.getMessage());
    return response;
  }
