spring-纯pojo切面

一.导包

<dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
  <version>4.12</version>
  <scope>test</scope>
</dependency>
<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-context</artifactId>
  <version>4.3.9.RELEASE</version>
</dependency>
<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-aspects</artifactId>
  <version>4.3.9.RELEASE</version>
</dependency>
二.代理类

package com.yztc.pojo;

import org.aspectj.lang.ProceedingJoinPoint;

/**
 * _ooOoo_
 * o8888888o
 * 88" . "88
 * (| -_- |)
 * O = /O
 * ___/`---'\____
 * .   ' \| |// `.
 * / \||| : |||// 
 * / _||||| -:- |||||- 
 * | | \ - /// | |
 * | \_| ''---/'' | |
 *  .-\__ `-` ___/-. /
 * ___`. .' /--.-- `. . __
 * ."" '< `.___\_<|>_/___.' >'"".
 * | | : `- \`.;` _ /`;.`/ - ` : | |
 *   `-. \_ __ /__ _/ .-` / /
 * ======`-.____`-.___\_____/___.-`____.-'======
 * `=---='
 * .............................................

 */


public class SleepAspect {



    public void before(){
        System.out.println("睡觉之前拖衣服");
    }
    public void afterReturning(){
        System.out.println("睡觉");
    }
    public void afterThrowing(Exception ex) throws Exception {
        System.out.println("出大事了,有bug");
        System.out.println(ex.getMessage());
    }
    public Object around(ProceedingJoinPoint pjp) throws Throwable{
        Object proceed =null;
        if (!"".equals("admin")){
            System.out.println("核心方法被执行");
            proceed = pjp.proceed(pjp.getArgs());
            System.out.println("核心方法执行完");
        }
        return proceed;
    }
}

三.代理接口和实现类

package com.yztc.pojo;

public interface SleepDao {
    public String sleep(String name) throws Exception;
}

package com.yztc.pojo;

/**
 * _ooOoo_
 * o8888888o
 * 88" . "88
 * (| -_- |)
 * O = /O
 * ___/`---'\____
 * .   ' \| |// `.
 * / \||| : |||// 
 * / _||||| -:- |||||- 
 * | | \ - /// | |
 * | \_| ''---/'' | |
 *  .-\__ `-` ___/-. /
 * ___`. .' /--.-- `. . __
 * ."" '< `.___\_<|>_/___.' >'"".
 * | | : `- \`.;` _ /`;.`/ - ` : | |
 *   `-. \_ __ /__ _/ .-` / /
 * ======`-.____`-.___\_____/___.-`____.-'======
 * `=---='
 * .............................................
 *
 * @author bindu
 * @date 2017-10-19 14:01
 */


public class SleepDaoImpl implements SleepDao {
    @Override
    public String sleep(String name) throws Exception {
        if (!name.equals("xm")){
            throw new Exception("睡你妹啊,起来嗨杯");
        }
        System.out.println("开始睡觉");
        return "小明";
    }
}

纯pojo切面 ,配置xml文件:spring-context.xml

代码不变，只是修改配置文件,加入AOP配置即可

<?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">

    <bean id="sleep" class="com.yztc.pojo.SleepDaoImpl"/>
    <bean id="sleepAspect" class="com.yztc.pojo.SleepAspect"/>

    <!--proxy-target-class="true" 表示使用cglib代理-->
    <!--配置AOP-->
    <aop:config>
        <!--切面-->
        <aop:aspect id="aspect" ref="sleepAspect">
            <!--切入点的配置-->
            <aop:pointcut id="pointcut" expression="execution(* com.yztc.pojo.*.Sleep.*(..))"/>

            <aop:before method="before" pointcut-ref="pointcut"/>
            <aop:after-throwing method="afterThrowing" throwing="ex" pointcut-ref="pointcut"/>
            <aop:around method="around" pointcut-ref="pointcut"/>
            <aop:after-returning method="afterReturning" pointcut-ref="pointcut"/>
        </aop:aspect>
    </aop:config>
</beans>

四.测试

package com.yztc.pojo;

import org.springframework.context.support.ClassPathXmlApplicationContext;

/**
 * _ooOoo_
 * o8888888o
 * 88" . "88
 * (| -_- |)
 * O = /O
 * ___/`---'\____
 * .   ' \| |// `.
 * / \||| : |||// 
 * / _||||| -:- |||||- 
 * | | \ - /// | |
 * | \_| ''---/'' | |
 *  .-\__ `-` ___/-. /
 * ___`. .' /--.-- `. . __
 * ."" '< `.___\_<|>_/___.' >'"".
 * | | : `- \`.;` _ /`;.`/ - ` : | |
 *   `-. \_ __ /__ _/ .-` / /
 * ======`-.____`-.___\_____/___.-`____.-'======
 * `=---='

public class TestMain {



    public static void main(String[] args) {
        String xm=null;
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("spring-context.xml");
        SleepDao sleep = (SleepDao) context.getBean("sleep");
        try {
            xm = sleep.sleep("xm");
        } catch (Exception e) {
            e.printStackTrace();
        }
        System.out.println(xm);
    }
}
