先定义一个接口：

package com.chinasoft.pur; public interface Purview { public void logincheck(); }

实现类：

package com.chinasoft.pur; public class PurviewImpl implements Purview{ public void logincheck() { System.out.println("login....."); } }

拦截logincheck之前具体要处理的：

package com.chinasoft.pur; import java.lang.reflect.Method; import org.springframework.aop.MethodBeforeAdvice; public class BeforeMethod implements MethodBeforeAdvice{ public void before(Method arg0, Object[] arg1, Object arg2)throws Throwable { System.out.println("befor login..."); } }

在applicationContext.xml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:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> <bean id="purviewimpl" class="com.chinasoft.pur.PurviewImpl"></bean> <bean id="beforem" class="com.chinasoft.pur.BeforeMethod"></bean> <bean id="puradvice" class="org.springframework.aop.support.RegexpMethodPointcutAdvisor"> <property name="advice"> <ref bean="beforem"/> </property> <property name="pattern"> <value>.*logincheck*.</value> </property> </bean> <bean id="autoproxy" class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator"> <property name="beanNames"> <value>purviewimpl</value> </property> <property name="interceptorNames"> <value>puradvice</value> </property> </bean> </beans>

测试类：

package com.chinasoft.pur; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class Test { /** * @param args */ public static void main(String[] args) { ApplicationContext context=new ClassPathXmlApplicationContext("applicationContext.xml"); Purview pur= (Purview) context.getBean("purviewimpl"); pur.logincheck(); } }

输出结果：

befor login... login.....
