java - Spring ExceptionHandler 未返回有效的响应代码

Question

我在 spring RestController 中有这样的异常处理程序。

   @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;
}

我期望结果:内容类型:application-json状态:403和正文:

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

但是结果是:状态:200，未设置内容类型。有什么建议吗？

你可以这样尝试吗？这是一个代码片段，请根据要求进行修改。

@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);
        }
    }
