Question

我有以下异常处理程序：

@ControllerAdvice
public class MyExceptionHandler {
  private static final Logger logger = LoggerFactory.getLogger(MyExceptionHandler.class);
    @ExceptionHandler
    @ResponseStatus(HttpStatus.BAD_REQUEST)
    public void handle(HttpMessageNotReadableException e) {
        logger.warn("HttpMessageNotReadableException occurred.", e);
        throw e;
    }

但它没有抓住HttpMessageNotReadableException？！在我的日志中，我看到（它打印弹簧本身）：

2017-07-04 13:26:38,699 DEBUG org.springframework.web.servlet.mvc.method.annotation.ServletInvocableHandlerMethod.getMethodArgumentValues:164 - Failed to resolve argument 0 of type 'com.finvale.model.Client'

是否可以在我的ExceptionHandler中捕获此异常？

P.S。

我同意我的代码包含错误。我需要在注释中指定类型。我这样改了：

 @ExceptionHandler(HttpMessageNotReadableException.class)
    @ResponseStatus(HttpStatus.BAD_REQUEST)
    public void handle(HttpMessageNotReadableException e) {

但我仍然看到同样的行为。

handle方法无法调用

Answer 1

您必须指定处理程序需要处理的类。像：

@ExceptionHandler(HttpMessageNotReadableException.class)

例如，请参阅here以进一步阅读。或者there进行关于弹簧和异常处理的“完整”讨论。

Answer 2

将@ExceptionHandler更改为@ExceptionHandler(value = HttpMessageNotReadableException.class)

而不是重新抛出相同的异常，最好以有意义的方式返回包含该错误消息的自定义对象

Answer 3

最后我找到了解决方案：

根本原因是<div class="kk-star-ratings top-right rgt" data-id="18">hide</div> <div class="kk-star-ratings top-right rgt" data-id="9036">hide</div> <div class="kk-star-ratings top-right rgt" data-id="11218">show</div> <div class="kk-star-ratings top-right rgt" data-id="98756036">show</div>

有2个地方

内部控制器
在相关描述的已分离班级@ExceptionHandler内。

我将方法移到了MyExceptionHandler，它开始工作了。

@ExceptionHandler没有捕获HttpMessageNotReadableException
