Spring之AOP XML方式

xml方式和Annotation方式差不多，只需改动代理类，和配置文件即可。

package aspect; import org.aspectj.lang.annotation.After; import org.aspectj.lang.annotation.AfterReturning; import org.aspectj.lang.annotation.AfterThrowing; import org.aspectj.lang.annotation.Around; import org.aspectj.lang.annotation.Aspect; import org.aspectj.lang.annotation.Before; import org.aspectj.lang.annotation.Pointcut; public class UserDaoAspect { public void startSay(){ //告知在xml文件中配置为前置通知 System.out.println("Good Morning"); } public void endSay(){ //告知在xml文件中配置为后置通知 System.out.println("bye bye"); } }

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:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd"> <bean id="userDao" class="dao.UserDaoImpl" /> <bean id="aspectj" class="aspect.UserDaoAspect"></bean> <aop:config> <aop:aspect id="myaspectj" ref="aspectj"> <aop:pointcut expression="execution(* dao..*.*(..))" id="mypointcut"/> <aop:before method="startSay" pointcut-ref="mypointcut"/><!-- 前置通知 --> <aop:after method="endSay" pointcut-ref="mypointcut"/> <!-- 后置通知 --> </aop:aspect> </aop:config> </beans>

测试类

package test; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import dao.UserDao; import dao.UserDaoImpl; public class Test { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub ApplicationContext context=new ClassPathXmlApplicationContext("applicationContext.xml"); UserDao dao=(UserDao)context.getBean("userDao"); dao.addUser(); } }

两种方式效果是一样的
