aop拦截springmvc的action不成功!(已解决)

今天做了个aop的试验,对于springmvc的action不能拦截成功,研究了很久,没有找到问题,所以请教下大家.
下面是代码:

1.springmvc的action:

package com.sure.demo.web;

import java.util.Date;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;

import org.springframework.web.servlet.mvc.multiaction.MultiActionController;

public class DemoTestAction extends MultiActionController {

//返回的test页面

private String testPage;

public String getTestPage() {

return testPage;

}

public void setTestPage(String testPage) {

this.testPage = testPage;

}

/**

* test入口

* @param request

* @param response

* @return

* @throws Exception

public ModelAndView test(HttpServletRequest request,

HttpServletResponse response) throws Exception {

ModelAndView mav = null;

mav = new ModelAndView(this.getTestPage());

request.setAttribute("test", new Date().toString());

return mav;

}

2.jsp代码:

<%@ page language="java" import="java.util.*" pageEncoding="gb2312"%>

String test = (String)request.getAttribute("test");

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

<head>

</head>

<body>

当前时间是:<%=test %> <br>

</body>

</html>

3.aop代码:

package com.sure.aopdemo;

import org.aspectj.lang.JoinPoint;

public class AopDemoTestImpl {

public void afterTest(JoinPoint joinPoint) {

System.out.println("aop--执行类:"+joinPoint.getThis()+"的"+joinPoint.getSignature().getName()+"方法之后");

}

public void beforeTest(JoinPoint joinPoint) {

System.out.println("aop--执行类:"+joinPoint.getThis()+"的"+joinPoint.getSignature().getName()+"方法之前");

}

public void exceptionTest() {

System.out.println("aop方法异常");

}

4.xml关于aop的配置:

<?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"

xmlns:tx="http://www.springframework.org/schema/tx"

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd

http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd

http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd">

<aop:config>

<aop:aspect id="test" ref="aopDemoTestImpl">

<aop:pointcut id="a" expression="execution(* com.sure.demo..*.*(..))"/>

<aop:before method="beforeTest" pointcut-ref="a"/>

<aop:after method="afterTest" pointcut-ref="a"/>

<aop:after-throwing method="exceptionTest" pointcut-ref="a"/>

</aop:aspect>

</aop:config>

</beans>
