Spring代理處理參數和方法

Spring代理處理參數和方法:

 

1. package com.rx.spring.dynamicmock;
3. public interface UserManager {
5.     public void addUser(String username, String password);
6.     
7.     public void deleteUser(int id);
8.     
10. }

 

1. package com.rx.spring.dynamicmock;
3. public class UserManagerImpl implements UserManager {
5.     public void addUser(String username, String password) {
6.         System.out.println("-------UserManagerImpl.addUser()----------");
7.     }
9.     public void deleteUser(int id) {
10.         System.out.println("-------UserManagerImpl.deleteUser()----------");
11.     }
14. }

 

1. package com.rx.spring.dynamicmock;
3. import org.aspectj.lang.JoinPoint;
5. public class SecurityHandler {
6.     
7.     /***
8.      * 處理連接點
9.      * @param joinPoint 
10.      */
11.     private void checkSecurity(JoinPoint joinPoint) {
12.         
13.         Object[] args = joinPoint.getArgs();
14.         for (int i=0; i<args.length; i++) {
15.             System.out.println(args[i]);
16.         }
17.         
18.         System.out.println(joinPoint.getSignature().getName());
19.         
20.         System.out.println("----------checkSecurity()---------------");
21.     }
22.     
23. }

 

1. package com.rx.spring.dynamicmock;
3. import org.springframework.beans.factory.BeanFactory;
4. import org.springframework.context.support.ClassPathXmlApplicationContext;
6. public class Client {
8.     public static void main(String[] args) {
9.         BeanFactory factory = new ClassPathXmlApplicationContext("applicationContextMockSpring.xml");
10.         
11.         UserManager userManager = (UserManager)factory.getBean("userManager");
12.         
13.         userManager.addUser("abc", "123");
14.         
15.     }
16. }
