@RestControllerAdvice
public class MyExceptionTranslator {

  @ExceptionHandler(Exception.class)
  @ResponseStatus(HttpStatus.OK)
  public String handleNotFoundException(CustomNotFoundException ex) {
    return ex.getMessage();
  }
}

@RestControllerAdvice
public class MyExceptionTranslator {

  @ExceptionHandler(Exception.class)
  @ResponseStatus(HttpStatus.OK)

  //自定義的異常處理
  @ExceptionHandler(CustomNotFoundException.class)
  @ResponseStatus(HttpStatus.OK)
  public ResponseMsg handleNotFoundException(CustomNotFoundException ex) {
    ResponseMsg responseMsg = new ResponseMsg(ex.getMessage());
    return responseMsg;
