aop-正则表达式方法切入点顾问

1、class MyAfterReturningAdvice

package com.aop08;

import java.lang.reflect.Method;

import org.springframework.aop.AfterReturningAdvice;
//后置通知:可以获取目标方法的返回结果，但无法改变目标方法的结果
public class MyAfterReturningAdvice implements AfterReturningAdvice {

//在目标方法执行之后执行
//returnValue:目标方法的返回值
@Override
public void afterReturning(Object returnValue, Method method, Object[] args, Object target) throws Throwable {
	System.out.println("执行后置通知方法");
	
}

}

2、class MyTest

package com.aop08;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class MyTest {

public static void main(String[] args) {
	
	String resource = "com/aop08/applicationContext.xml";
	ApplicationContext ac = new ClassPathXmlApplicationContext(resource);
	
	ISomeService service = (ISomeService) ac.getBean("serviceProxy");
	service.doFirst();
	System.out.println("------------------------------------");
	service.doSecond();
	System.out.println("------------------------------------");
	service.doThird();
}

}
