中介者模式（Mediator Pattern）是用来降低多个对象和类之间的通信复杂性。这种模式提供了一个中介类，该类通常处理不同类之间的通信，并支持松耦合，使代码易于维护。
package com.ceshi21; public interface Mediator { public void createMediator(); public void workAll(); }
package com.ceshi21; public abstract class User { private Mediator mediator; public Mediator getMediator(){ return mediator; } public User(Mediator mediator) { this.mediator = mediator; } public abstract void work(); }
package com.ceshi21; public class User1 extends User{ public User1(Mediator mediator){ super(mediator); } @Override public void work() { System.out.println("user1 exe!"); } }
package com.ceshi21; public class User2 extends User{ public User2(Mediator mediator){ super(mediator); } @Override public void work() { System.out.println("user2 exe!"); } }
package com.ceshi21; public class MyMediator implements Mediator{ private User user1; private User user2; public User getUser1() { return user1; } public User getUser2() { return user2; } @Override public void createMediator() { user1 = new User1(this); user2 = new User2(this); } @Override public void workAll() { user1.work(); user2.work(); } }
主要是通过这个类进行关联
package com.ceshi21; public class Test { public static void main(String[] args) { Mediator mediator = new MyMediator(); mediator.createMediator(); mediator.workAll(); } }
测试结果：
