动态代理AOP的配置

Common.Java

1. package com.aspect;  
2.   
3. public class Common {  
4.     public void fn()  
5.     {  
6.         System.out.println("****************");  
7.     }  
8.     public void tc()  
9.     {  
10.         System.out.println("|||||||||||||||||");  
11.     }  
12. }
    

check.java

1. package com.aspect;  
2.   
3. public class Check {  
4.     public void check()  
5.     {  
6.         System.out.println("验证!!!!!!!!!!!");  
7.     }  
8. }

web.xml配置文件如下

1. <?xml version="1.0" encoding="UTF-8"?>  
2. <web-app version="2.5"   
3.     xmlns="http://java.sun.com/xml/ns/javaee"   
4.     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   
5.     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee   
6.     http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">  
7.     <context-param>  
8.         <param-name>contextConfigLocation</param-name>  
9.         <param-value>classpath:applicationContext.xml</param-value>  
10.     </context-param>  
11.       
12.     <listener>   
13.         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>   
14.     </listener>  
15.       
16.     <welcome-file-list>  
17.         <welcome-file>index.jsp</welcome-file>  
18.     </welcome-file-list>  
19. </web-app>

applicationContext.xml配置文件如下

1. <?xml version="1.0" encoding="UTF-8"?>   
2.   
3. <beans xmlns="http://www.springframework.org/schema/beans"   
4.   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   
5.   xmlns:aop="http://www.springframework.org/schema/aop"   
6.   xmlns:tx="http://www.springframework.org/schema/tx"   
7.   xsi:schemaLocation="   
8.       http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd   
9.       http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd   
10.       http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">      
11.    
12.   <bean id="common" class="com.aspect.Common"/>   
13.   <bean id="check" class="com.aspect.Check"/>   
14.       
15.   <aop:config>   
16.     <aop:aspect id="deal" ref="check">   
17.       <aop:pointcut id="target" expression="execution(* com.aspect.Common.*(..))"/>   
18.       <aop:before method="check" pointcut-ref="target"/>   
19.     </aop:aspect>   
20.   </aop:config>   
21.       
22. </beans>

测试类Client.java

1. package com.aspect;  
2.   
3. import org.springframework.beans.factory.BeanFactory;  
4. import org.springframework.context.ApplicationContext;  
5. import org.springframework.context.support.ClassPathXmlApplicationContext;  
6. import org.springframework.context.support.FileSystemXmlApplicationContext;  
7.   
8. public class Client {  
9.     public static void main(String[] args) {  
10.         ApplicationContext factory=new ClassPathXmlApplicationContext("applicationContext.xml");
    
11.     }
12. }
    

1. //下面这句也可以   
2.     //  BeanFactory factory=new ClassPathXmlApplicationContext("applicationContext.xml");   
3.         Common c=(Common) factory.getBean("common");   
4.         c.fn();   
5.         c.tc();  
6.     }  
7. }

结果如下：

[html] view plain copy

1. 验证!!!!!!!!!!!  
2. ****************  
3. 验证!!!!!!!!!!!  
4. |||||||||||||||||
