[Spring] @Controller vs @RestController

@Controller
public class RestClassName{

  @RequestMapping(value={"/uri"})
  @ResponseBody
  public ObjectResponse functionRestName(){
      //...
      return instance
   }
}

@RestController
public class RestClassName{

  @RequestMapping(value={"/uri"})
  public ObjectResponse functionRestName(){
      //...
      return instance
   }
}

 

두 코드의 차이처럼 @RestController는 @ResponseBody가 기본적으로 추가되며,

response를 JSON/XML로 자동 변환해준다.

 

@RestControllerAdvice도 마찬가지로 @ControllerAdvice에 @ResponseBody가 기본값으로 추가된 것을 의미한다.
