1、环境

eclipse、spring-dist下所有jar、aopalliance.jar、aspectjrt.jar、aspectjweaver.jar、cglib-nodep.jar、commons-logging.jar

另：java 1.7以上版本用aspectj 1.7.2以上版本

2、项目搭建：

Java项目名：AopInAnnotaion

src下包：com.wind.beans、com.wind.interceptor、com.wind.test

资源文件夹:Resource

3、相关代码：

com.wind.beans.SimpleBeans:

package com.wind.beans;  
  
  
import org.springframework.stereotype.Component;  
  
  
@Component  
public class SimpleBean \{  
  
public void f()\{  
System.out.println("SimpleBean.f");  
\}  
  
\}

com.wind.Interceptor:

package com.wind.interceptor;  
  
  
import org.aspectj.lang.annotation.Aspect;  
import org.aspectj.lang.annotation.Before;  
import org.aspectj.lang.annotation.Pointcut;  
import org.springframework.stereotype.Component;  
  
  
@Aspect  
@Component  
public class SimpleInterceptor \{  
  
  
//SimpleBean包下所有方法  
@Pointcut("execution(\* com.wind.beans.SimpleBean.\*(..))")  
public void anyMethod()\{\}  
  
  
  
//引用上边的pointcut签名  
@Before("anyMethod()")  
public void p()\{  
System.out.println("anyMethod");  
\}  
\}

com.wind.test.AopTest:

package com.wind.test;  
  
  
import org.junit.Test;  
import org.springframework.context.ApplicationContext;  
import org.springframework.context.support.ClassPathXmlApplicationContext;  
import com.wind.beans.SimpleBean;  
  
  
public class AopTest \{  
@Test  
public void test()\{  
ApplicationContext context = new ClassPathXmlApplicationContext("classpath:aop.xml");  
SimpleBean sBean = (SimpleBean) context.getBean("simpleBean");  
sBean.f();  
\}  
\}

Resource资源文件夹下配置文件：aop.xml:

<?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:p="http://www.springframework.org/schema/p"  
xmlns:context="http://www.springframework.org/schema/context"  
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"  
xmlns:mvc="http://www.springframework.org/schema/mvc"  
xsi:schemaLocation="http://www.springframework.org/schema/beans  
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd  
http://www.springframework.org/schema/context  
http://www.springframework.org/schema/context/spring-context-3.0.xsd  
http://www.springframework.org/schema/tx  
http://www.springframework.org/schema/tx/spring-tx-3.0.xsd  
http://www.springframework.org/schema/aop  
http://www.springframework.org/schema/aop/spring-aop-3.0.xsd  
http://www.springframework.org/schema/mvc  
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">  
  
<aop:aspectj-autoproxy />  
  
<context:component-scan base-package="com.wind.\*" />  
</beans>

4、运行测试：

运行com.wind.test.AopTest类，出现

anyMethod

SimpleBean.f

说明成功。
