• 引入Spring框架開發的基本開發包,spring的傳統AOP的開發的包與aspectJ的開發包

• 建立spring配置檔案 applicationContext.xml

<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.xsd
				http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">
			
		</beans>
 

• 建立包結構

dao

package dao;

public class CustomerDaoImpl implements CustomerDao{

	@Override
	public void save() {
		System.out.println("dao save");
	}

}

切面類

package demo;

import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;


@Aspect//定義切面類的註解
public class AspectAnno {
	
	//定義前置通知（value填寫切入點表示式）
	@Before(value="execution(* *..*DaoImpl.save(..))")
	public void demo1() {
		System.out.println("before anno");
	}
	
	
	
}
 

• 將目標類與切面類配置到applicationContex.xml中，並設定自動代理

<?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.xsd
				http://www.springframework.org/schema/aop 
				http://www.springframework.org/schema/aop/spring-aop.xsd">
				
				
	<!-- 定義自動代理 -->
	<aop:aspectj-autoproxy/>
	<!-- spring 代理bean -->
	<bean id="ustomerDao" class="dao.CustomerDaoImpl"/>
	<!-- 定義切面類 -->
	<bean id="aspectAnno" class="demo.AspectAnno"/>
	
	
</beans>
 

• 編寫測試類

package demo;

import javax.annotation.Resource;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import dao.CustomerDao;

//定義@RunWith繼承junit測試環境，@ContextConfiguration初始化xml
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:applicationContext.xml")
public class Demo {
	
	//用@Resource獲得bean
	@Resource(name="ustomerDao")
	private CustomerDao cdao;
	
	//測試方法
	@Test
	public void demo1() {
		cdao.save();
	}
}

測試結果：
