Spring注入方式实现AOP

Spring注入方式实现AOP

lib包：



1：applicationcontext.xml

<?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"  

    xmlns:tx="http://www.springframework.org/schema/tx"  

    xsi:schemaLocation="   

             http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd   

             http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd   

             http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd"> 
             

<bean id="checkip" class="com.zn.service.impl.CheckipImpl"/>

<bean id ="checkHelper" class="com.zn.common.CheckHelper"/>

<aop:config>

<aop:aspect ref="checkHelper">

<aop:before method="beforeCheck" pointcut="execution(* *.check(..))"/>

<aop:after method="afterCheck" pointcut="execution(* *.check(..))"/>

</aop:aspect>

</aop:config>

</beans>

2：Checkipable.java

package com.zn.service;

public interface Checkipable {

//校验
void check();

}

3：实现类CheckipImpl.java

package com.zn.service.impl;

import com.zn.service.Checkipable;

public class CheckipImpl implements Checkipable{

public void check() {
// TODO Auto-generated method stub
System.err.println("登录校验");
}

}

4：CheckHelper.java

package com.zn.common;

public class CheckHelper{

public void afterCheck() {
// TODO Auto-generated method stub
System.err.println("登录后要记录日志");
}

public void beforeCheck() {
// TODO Auto-generated method stub
System.err.println("登录前要校验");
System.err.println("超过登录次数的要锁定");
}

}

5: MainTest.java

package com.zn;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.zn.service.Checkipable;

public class MainTest {

public static void main(String args[]){
ApplicationContext ct = new ClassPathXmlApplicationContext("applicationcontext.xml");         
Checkipable checker = (Checkipable)ct.getBean("checkip");        
checker.check();

}

}

运行结果：

登录前要校验

超过登录次数的要锁定

登录校验

登录后要记录日志
