getting JSON from a spring rest Controller

I'm trying to get only the response Body in format JSON from a Spring Rest Controller, my code is :

@ResponseBody
    @RequestMapping(value = "/userDetails", method = RequestMethod.GET, produces = "application/json")

    public UserInfo getUserDetails(Principal principal){
        return users.get(principal.getName());
    }

my Result is :

Response {_body: "{id: 001}", status: 200, ok: true, statusText: "OK", headers: Headers, …}.

how can i get only the body as Json thank's ....

Use @RestController 

@RestController
public class DemoController {
    @GetMapping("/userDetails")
    public UserInfo getUserDetails(Principal principal){
        return users.get(principal.getName());
    }

}

output:

{"id": 001}

Using the `@RestController` Annotation

Note: Spring 4.0 introduced @RestController, a specialized version of the controller which is a convenience annotation that does nothing more than add the @Controller and @ResponseBody annotations. By annotating the controller class with @RestController annotation, you no longer need to add @ResponseBody to all the request mapping methods. The @ResponseBody annotation is active by default.

@RestController = @Controller + @ResponseBody

@RestController public class DemoController {

@RequestMapping(method = RequestMethod.POST,
        value = "userdetails",
        consumes = "application/json",
        produces = "application/json")
public UserInfo getUserDetails(@RequestBody Principal principal){
    return users.get(principal.getName());
}

}

other way work around

Remove the @ResponseBody annotation from the method.
