用于拦截所有异常的Spring AOP配置 [英] Spring AOP Configuration for Intercepting All Exceptions

问题描述

我正在努力编写/配置一个ThrowsAdvice拦截器，我想拦截整个项目中抛出的所有异常：

I am struggling to write/configure a ThrowsAdvice interceptor that I want to intercept all exceptions thrown throughout my project:

public class ExceptionsInterceptor implements ThrowsAdvice
{
    public void afterThrowing(final Method p_oMethod, final Object[] p_oArgArray,
        final Object p_oTarget, final Exception p_oException)
    {
        System.out.println("Exception caught by Spring AOP!");
    }
}

我已经成功配置了拦截特定的MethodInterceptor实现我想要分析的方法（看它们执行需要多长时间）。这是我到目前为止的XML配置文件：

I have already successfully configured a MethodInterceptor implementation that intercepts particular methods that I want to profile (see how long it takes them to execute). Here is the XML config file I have so far:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd"/>

<bean name="profilingInterceptor" class="org.me.myproject.aop.ProfilingInterceptor"/>

<bean name="exceptionsInterceptor" class="org.me.myproject.aop.ExceptionsInterceptor"/>

<aop:config>
    <aop:advisor advice-ref="profilingInterceptor" pointcut="execution(* org.me.myproject.core.Main.doSomething(..))"/>
</aop:config>

My ProfilingInterceptor工作正常且截获正是当我的Main :: doSomething（）方法被调用时 - 所以我知道我是ontrack。使用XmlSpy来查看Spring AOP的模式，看起来我可以添加类似下面的内容，以便让我的ExceptionsInterceptor拦截所有抛出的异常：

My ProfilingInterceptor works perfectly and intercepts precisely when my Main::doSomething() method gets invoked - so I known I'm ontrack. Using XmlSpy to look at Spring AOP's schema, it looks like I can add something like the following in order to get my ExceptionsInterceptor to intercept all thrown exceptions:

<aop:aspect>
    <after-throwing method=""/>
</aop:aspect>

但是我找不到任何以此为例的文档，我不知道如何配置方法属性，使其成为通配符（*）并匹配所有类和所有方法。

However I cannot find any documentation where this is used as an example, and I have no idea how to configure the method attribute so that its a "wildcard" (*) and matches all classes and all methods.

有人能指出我正确的方向吗？提前致谢！

Can anyone point me in the right direction? Thanks in advance!

推荐答案

根据aspectJ示例，方法参数是指 @AfterThrowing 的建议方法：

According to aspectJ examples method parameter refers to @AfterThrowing advice method:

@Aspect
public class LoggingAspect {

  @AfterThrowing(
   pointcut = "execution(* package.addCustomerThrowException(..))",
   throwing= "error")
  public void logAfterThrowing(JoinPoint joinPoint, Throwable error) {
    //...
  }
}    

然后配置：

 <aop:after-throwing method="logAfterThrowing" throwing="error"   />
