Spring @work Demo

定义一个接口
java 代码

package com.tyq.spring.aop.annotation;

public interface Say {
    void say();
    void say(String str);
    String say(String str,int i);
}

实现接口

java 代码

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

public class SayImpl implements Say {
    private static final Log log = LogFactory.getLog(SayImpl.class);
    @Override
    public void say() {
        System.out.println(this.getClass().getMethods()[0]);

    }

    @Override
    public void say(String str) {
        System.out.println(this.getClass().getMethods()[0]);

    }

    @Override
    public String say(String str, int i) {
        System.out.println(str + i);
        return str;
    }

}

@Aspect的定义

java 代码

package com.tyq.spring.aop.annotation;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;

@Aspect
public class AopAfterReturning {
    @Pointcut("execution(* Say.*(..))")
    public void test(){
        System.out.println("hello");
    }
    @AfterReturning("test()")
    public void afterTest()
    {
        System.out.println(this.getClass());
    }
}

applicationContex.xml配置文件

xml 代码

xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <bean id="aspect" class="com.tyq.spring.aop.annotation.AopAfterReturning"/>
    <bean id="sayImpl" class="com.tyq.spring.aop.annotation.SayImpl"/>

主函数入口

java 代码

package com.tyq.spring.aop.annotation;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestMain {

    /**
    * @param args
    */
    protected static Log log = LogFactory.getLog(TestMain.class);
    public static void main(String[] args){
        ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml",TestMain.class);
        Say test = (Say)context.getBean("sayImpl");
        test.say();
        test.say("how are you!");
        test.say("who are you !", 2);
        log.info("hello");
    }

}
