弹簧启动方面如何在请求中捕获参数解析器异常的异常

Question

我是春季的新内容，并尝试使用AOP方面来处理程序中所有可能的异常。除了请求解析器异常外，它运行良好，因为我的方面无法捕获它。案例如下： 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，其封装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，如果我发送类似"127.0.0.1：9999/test？para=ABC"的请求，testApi 将抛出一个 MethodArgumentTypeMismatchException，但它不会被我的 Aspect 捕获。 但是，可以捕获"做某事"中引发的任何其他异常。

所以，我很困惑，我是否在Aspect上的配置是错误的，或者Aspect只是无法捕获此类异常。

非常感谢您的建议！

//-------------------------------------------------------------------------- 在@M.Deinum的评论之后，我添加了一个带有注释"@RestControllerAdvice"的GlobalExceptionHandler。现在，可以处理控制器内部未抛出的此类异常。

您可以尝试扩展OncePerRequestFilter类并重写doFilterInternal方法。类似以下内容的内容就可以解决问题：

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.
}
}
