HTTP Status 400 - Required short parameter 'score' is not present, Spring MVC REST

Question

I am using Spring MVC 4. Here is my controller code:

@RestController
public class NewValueController 
{
   @RequestMapping(value="/receiveUpdatedScore",method=RequestMethod.POST,produces={"application/json"})
   public NewValue receiveUpdateScore(@RequestParam(value="score") short score,
                               @RequestParam(value="user_id") String user_id,
                               @RequestParam(value="device_model") String device_model,
                               @RequestParam(value="api_key") String api_key,
                               @RequestParam(value="gen_t") long gen_t,
                               Model model)
  {
    int newScore = (int) score;
    NewValue algorithm=new NewValue();
    NewValue newvalue=algorithm.getNextValue(newScore);
    return newvalue;
  }
}

I am making this Request using Advanced rest client(also tried same in Postman):

{"score":"50","user_id":"zyz","device_model":"xiami","api_key":"sasa5454","gen_t":"545666"}

But I am getting following error

Error:

HTTP Status 400 - Required Short parameter 'score' is not present

message: Required Short parameter 'score' is not present

description: The request sent by the client was syntactically incorrect.

What is the mistake I am not able to detect here. Please help me to resolve it.

I think this is because score is expected as part of the url and not some JSON that you post
