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
