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
