Java 弹簧靴1.4.3和@ControllerAdvice

我有一个带有ControllerAdvice扩展ResponseEntityExceptionHandler的Spring4应用程序，当异常出现时，它可以正常工作

@ControllerAdvice
@Slf4j
public class ExceptionManager extends ResponseEntityExceptionHandler {

    @Override
    protected ResponseEntity<Object> handleMethodArgumentNotValid(MethodArgumentNotValidException ex,
                                                                  HttpHeaders headers,
                                                                  HttpStatus status,
                                                                  WebRequest request) {
        final ValidationErrors errors = getErrors(ex.getBindingResult());
        headers.setContentType(MediaType.APPLICATION_JSON);
        return handleExceptionInternal(ex, errors, headers, HttpStatus.BAD_REQUEST, request);
    }


    @Override
    protected ResponseEntity<Object> handleBindException(BindException ex, HttpHeaders headers, HttpStatus status, WebRequest request) {
        final ValidationErrors errors = getErrors(ex.getBindingResult());
        headers.setContentType(MediaType.APPLICATION_JSON);
        return handleExceptionInternal(ex, errors, headers, HttpStatus.BAD_REQUEST, request);
    }

    @ExceptionHandler(ValidationException.class)
    public ResponseEntity handleValidationException(ValidationException ex) {
        log.warn("Validation error", ex);
        return ex.toResponseEntity();
    }

    @ExceptionHandler(HttpClientErrorException.class)
    public ResponseEntity handleHttpClientErrorException(HttpClientErrorException ex) {
        log.error(ex.getMessage());
        return new ResponseEntity(ex.getResponseBodyAsString(), ex.getStatusCode());
    }

    @ExceptionHandler({Exception.class, RuntimeException.class})
    protected ResponseEntity<Object> handleRootException(Exception ex, WebRequest request) {
        return handleException(request, ex);
    }

...
}

例外情况未被捕获！ 它发生在特定情况下，@RestController使用调用外部端点的服务时。在我的例子中，外部服务返回一个XML，如果它像上面的异常一样被破坏，那么SAXParseException将不会被捕获，并在spring之前自动转换为一个400错误请求和一个空正文。它也根本不被记录

如果在我的RestController中，我添加了一个方法@ExceptionHandlerThrowable.class，就会调用这个方法，我可以控制返回的错误

这正常吗？我认为ControllerAdvice可以集中所有异常处理，消除每个控制器中都需要ExceptionHandler的需要。

刚刚找到了解决方案：删除extends ResponseEntityExceptionHandler。如果@ControllerAdvice不扩展任何内容，看起来效果会更好。

内部handleRootExceptioninside方法pass Throwable而不是Exception ex@VinayPrajapati我已将其更新为@ExceptionHandlerThrowable.class@ResponseBody public ResponseEntity HandlerOotexception rowable ex，WebRequest req{log.errorException received:，ex；返回新的ResponseEntityex，HttpStatus.INTERNAL_SERVER_ERROR；}但是仍然没有调用，因此如果将此代码放在控制器中，则此代码可以正常工作。如果您没有打印整个异常堆栈跟踪，“原因”表示它是一个包装异常，而不是实际引发的顶级异常。@Gimby我在控制器中使用@ExceptionHandler时添加了完整的堆栈。仅供参考，XML响应为brok在标记的中间有一个行返回以引发异常。因此，实际可捕获的异常是HttpMessageNodeTableException；如果您没有专门处理它，则应调用通用handleRootException。这没有发生？实际上这不是一个正确的解决方案。它确实会捕获SAXParseException，但随后它不会s不再捕获其他一些，如MethodArgumentNotValidException，我想是因为ResponseEndityExceptionHandler.handleMethodArgumentNotValid不再被覆盖是的，当定义一个用@ExceptionHandlerMethodArgumentNotValidException.class注释的方法时，事件没有被捕获。好吧，还是比以前更好。。。
