Java AOP切面编程，spring 配置文件开发方式

一，定义主要接口

package c.c.aop;

/*
* 接口类
* 主要要做的事
*
* */

public interface Sleepable {

void sleep();

}

二，继承主要接口重写类

package c.c.aop;

public class Human implements Sleepable {

/*
* 接口实现类
* 重写接口类方法
*
* */
public void sleep(){
System.out.println("睡觉了！梦中自有颜如玉！");
}

}

三，切面新添加的要执行的类

package c.c.aop;

import java.lang.reflect.Method;

import org.springframework.aop.AfterReturningAdvice;
import org.springframework.aop.MethodBeforeAdvice;

/*
* 切面通知类
* */

public class SleepHelper implements MethodBeforeAdvice,AfterReturningAdvice{

public void before(Method mtd, Object[] arg1, Object arg2)
throws Throwable {
System.out.println("通常情况下睡觉之前要脱衣服！");
}

public void afterReturning(Object arg0, Method arg1, Object[] arg2, Object arg3) throws Throwable {
System.out.println("起床后要先穿衣服！");
}

}

四，测试的main 方法

package c.c.aop;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestAOP {

@SuppressWarnings("resource")
public static void main(String[] args){
ApplicationContext appCtx = new ClassPathXmlApplicationContext("beans-mybatis.xml");
Sleepable sleeper = (Sleepable)appCtx.getBean("humanProxy");
sleeper.sleep();
}

}

五，配置文件
