Spring的AOP使用xml配置

需要使用spring的包，大家自己全部导入进去即可。省4........

用户管理接口

package com.rx.spring;

public interface UserManager {

public void addUser(String username, String password);

public void deleteUser(int id);

}

用户管理实现

package com.rx.spring;

public class UserManagerImpl implements UserManager {

public void addUser(String username, String password) {
System.out.println("-------UserManagerImpl.addUser()----------");
}

public void deleteUser(int id) {
System.out.println("-------UserManagerImpl.deleteUser()----------");
}

}

切面

package com.rx.spring;

public class SecurityHandler {

private void checkSecurity() {
System.out.println("----------checkSecurity()---------------");
}

}

applicationContext.xml内容如下：

<?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-2.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd">

<bean id="securityHandler" class="com.rx.spring.SecurityHandler"/>

<bean id="userManager" class="com.rx.spring.UserManagerImpl"/>

<aop:config>
<aop:aspect id="security" ref="securityHandler">
<aop:pointcut id="allAddMethod" expression="execution(* com.rx.spring.UserManagerImpl.add*(..))"/>
<aop:before method="checkSecurity" pointcut-ref="allAddMethod"/>
<aop:after method="checkSecurity" pointcut-ref="allAddMethod"/>
</aop:aspect>
</aop:config>
</beans>

客户端调用:

package com.rx.spring;

import org.springframework.beans.factory.BeanFactory;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Client {

public static void main(String[] args) {
BeanFactory factory = new ClassPathXmlApplicationContext("applicationContext.xml");

UserManager userManager = (UserManager)factory.getBean("userManager");

userManager.addUser("sd", "123");
userManager.deleteUser(1);
}
}

运行结果：

----------checkSecurity()---------------

-------UserManagerImpl.addUser()----------

----------checkSecurity()---------------

-------UserManagerImpl.deleteUser()----------
