Java spring引导方面如何在请求中捕获para解析器异常的异常

我是春天的新手，正在尝试使用AOP方面来处理我程序中所有可能的异常。除了请求para解析器异常之外，它工作得很好，因为我的方面无法捕获它。情况如下： 这是我的方面代码

@Aspect
@Order(5)
@Component
public class WebLogAspect {
  private static final Logger LOG = LoggerFactory.getLogger(WebLogAspect.class);
  @Pointcut("execution(public * com.test.api..*.*(..))")
  public void webLog() {}

  @AfterThrowing(pointcut = "webLog()", throwing = "e")
  public void afterThrowing(Throwable e) {

      LOG.error(e.getMessage(), e);
   }
}

然后是控制器部分，它的包路径正好包含在方面切入点中

@RestController
public class TestController {

   @RequestMapping("/test")
   public Long testApi(
     @RequestParam(value = "para", required = true)Long testPara) {
        /*           
        do some thing;
        */ 
       return testPara;
     }
}

问题是，如果我发送像“127.0.0.1:9999/test？para=ABC”这样的请求，testApi将抛出MethodArgumentTypeMismatchException，但它不会被我的方面捕获。但是，可以捕获“Dosomething”中引发的任何其他异常

所以，我很困惑，我在方面的配置是错误的，还是方面无法捕捉到这样的异常

非常感谢你的建议

//-------------------------------------------------------------------------- 在@M.Deinum的评论之后，我添加了一个带有注释“@RestControllerAdvice”的GlobalExceptionHandler。现在，可以处理未在控制器内引发的此类异常

您可以尝试扩展

OncePerRequestFilter

类并重写

doFilterInternal

方法。类似于以下内容的操作将实现此目的：

    public void doFilterInternal(final HttpServletRequest request, final HttpServletResponse response,
            final FilterChain filterChain) throws ServletException, IOException {

    try {
        filterChain.doFilter(request, response);
    } catch (RuntimeException e) { 
    // Any exception thrown from your code can be handled or retrhown from here.
    }
}

您确定testApi方法中引发了MethodArgumentTypeMismatchException吗？我猜它是从其他地方抛出的，然后传播到testApi中。它本身无法捕获您的异常。在调用实际方法之前引发异常。因此，在执行方面之前。@fg78cn是的，我猜异常是在处理testApi之前抛出的。但不确定，来这里征求意见：）@M.Deinum谢谢！这就是我的猜测。@EricOlivier-你可以在你的testApi中捕获Throwable，然后重新抛出它，这样aspect就可以工作了。
