1、目标类

package com.gec.target;public class Hadoop { public void eatting() { System.out.println("大象正在吃东西 1"); try { //耗时5秒 Thread.sleep(5000); } catch (InterruptedException e) { e.printStackTrace(); } }}

2、增强类，此类必须要实现增强方位接口

package com.gec.advice; import org.springframework.aop.MethodBeforeAdvice; import java.lang.reflect.Method; public class BeforeMethodAdvice implements MethodBeforeAdvice { @Override public void before(Method method, Object[] objects, Object o) throws Throwable { System.out.println("how are you"); } }

3、配置文件

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://.gec.target.Hadoop" /> <aop:config> <!--定义一个切面--> <aop:advisor advice-ref="beforeMethodAdvice" pointcut="execution (* eatting(..))" /> </aop:config> </beans>

4、测试

public static void main(String[] args) { ApplicationContext ctx=new ClassPathXmlApplicationContext("beans.xml"); Hadoop hadoop= (Hadoop) ctx.getBean("hadoop"); hadoop.eatting(); }
