Spring ExceptionHandler不返回有效的響應代碼

Question

我在Spring RestController中有這樣的異常處理程序。

   @ExceptionHandler(AuthException.class)
public ResponseEntity<String> handleCustomException(AuthException ex, Writer writer) throws IOException {

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);

    ResponseEntity responseEntity = new ResponseEntity(headers, HttpStatus.FORBIDDEN);
    (new ObjectMapper()).writeValue(writer, ex.getAsMap());

    return responseEntity;
}

我期望結果：內容類型：application-json狀態：403和正文：

{"date":"06-06-2019 18:36:34","errorCode":"102","error":"Login or password is not right","message":"Access denied"}

但是結果是：狀態：200，並且未設置Content-type。 有什么建議么？

你可以這樣嘗試嗎 這是一個代碼段，請根據要求進行修改。

@ControllerAdvice
    public class GlobalExceptionHandler{
        @ExceptionHandler(MyCustomException.class)
        @ResponseBody
        public ResponseEntity<?> handleCustomException(MyCustomException e) {        
            String bodyJson = "Fatal Exception while performing.";
            return ResponseEntity.status(HttpStatus.FORBIDDEN).contentType(MediaType.APPLICATION_JSON).body(bodyJson);
        }
    }
