package aop;public interface Purview { void checkLogin();} Purview接口的实现类PurviesImpl.java
package aop;public class PurviewImpl implements Purview { public void checkLogin() { System.out.println("This is checkLogin method!"); }} 拦截器类PurviewAdvice.java
package aop;import java.lang.reflect.Method;import org.springframework.aop.MethodBeforeAdvice;public class PurviewAdvice implements MethodBeforeAdvice { public void before(Method arg0, Object[] arg1, Object arg2) throws Throwable { System.out.println("This is before method!"); }} 测试类Test.java
package aop;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class Test {public static void main(String[] args) {// TODO 自动生成方法存根ApplicationContext ctx = new ClassPathXmlApplicationContext("aop/applicationContext.xml");Purview purview = (Purview) ctx.getBean("purviewImpl");purview.checkLogin();}} 配置文件applicationContext.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:aop="http://www.springframework.org/schema/aop"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-2.5.xsd"default-autowire="autodetect"><bean id="purviewImpl" class="aop.PurviewImpl"></bean><bean id="purviewAdvice" class="aop.PurviewAdvice"></bean><bean id="purviewAdvisor"class="org.springframework.aop.support.RegexpMethodPointcutAdvisor"><property name="advice"><ref local="purviewAdvice" /></property><property name="patterns"><list><value>.*checkLogin.*</value></list></property></bean><bean id="autoproxyaop"class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator"><property name="beanNames"><value>purviewImpl</value></property><property name="interceptorNames"><list><value>purviewAdvisor</value></list></property></bean></beans>
