@RestControllerAdvice vs @ControllerAdvice

Question

• What are the major difference between @RestControllerAdvice and @ControllerAdvice ??
• Is it we should always use @RestControllerAdvice for rest services and @C

Answer 1

In addition, we can just understand it as:

@RestControler = @Controller + @ResponseBody

@RestControllerAdvice = @ControllerAdvice + @ResponseBody.

Keeping in mind that @ControllerAdvice is more convenient annotation for handling Exception with RestfulApi.

Example os usage:

@RestControllerAdvice
public class WebRestControllerAdvice {

  @ExceptionHandler(CustomNotFoundException.class)
  public ResponseMsg handleNotFoundException(CustomNotFoundException ex) {
    ResponseMsg responseMsg = new ResponseMsg(ex.getMessage());
    return responseMsg;
  }
}

In that case any exception instanceOf CustomNotFoundException will be thrown in body of response.
