The request sent by the client was syntactically incorrect ().+Spring , RESTClient

Question

I am working with Spring MVC using JSON objects. while I am tring to send JSON Object from RESTClient, I am getting

HTTP Status 400 - The request sent by the client was syntactically incorrect ().

This is my controller

ObjectMapper mapper=new ObjectMapper();
@RequestMapping(value = "/addTask", method = RequestMethod.GET)
       public ModelAndView addTask(@RequestParam("json") String json) throws JsonParseException, JsonMappingException, IOException 
       {
          System.out.println("Json object from REST : "+json);
          Task task=(Task) mapper.readValue(json, Task);
          service.addService(task);
          return new ModelAndView("Result");
       }

My request URL : http://localhost:8080/Prime/addTask

My Json Object :

{"taskName":"nothing","taskId":1234,"taskDesc":"nothing doing"}

Also i tried specifying "Content-Type: application/json" in RESTClient but still am getting the same error

Try this

Change

@RequestParam("json") String json

To

 @RequestBody Task task

If you are not interested in POST method you can try this

change your Controller method from

@RequestMapping(value = "/addTask", method = RequestMethod.GET)
   public ModelAndView addTask(@RequestParam("json") String json)

to

@RequestMapping(value = "/addTask/{taskName}/{taskId}/{taskDesc}", method = RequestMethod.GET)
   public ModelAndView addTask(@RequestParam("taskName") String taskName,
@RequestParam("taskId") String taskId,@RequestParam("taskDesc") String taskDesc)

and change your URL to

http://localhost:8080/Prime/addTask/mytask/233/testDesc
