/*** Created by TigerChain* 代理人，我上场了，感觉像媒婆*/public class ProxyTigerChain implements ZhuimmWay {private XiaoMing xiaoMing ;public ProxyTigerChain(XiaoMing xiaoMing, MM mm){this.xiaoMing = xiaoMing ;xiaoMing.like(mm);}@Overridepublic void giveFlowers() {xiaoMing.giveFlowers();}@Overridepublic void writeLoveLetters() {xiaoMing.writeLoveLetters();}@Overridepublic void buyClothes() {xiaoMing.buyClothes();}@Overridepublic void doSomthing() {xiaoMing.doSomthing();}}
public class Test {public static void main(String args[]){// 主人公小明XiaoMing xiaoMing = new XiaoMing();// 要追的人小倩MM xiaoqian = new MM("小倩") ;// 小明委托我去帮他追小倩ProxyTigerChain proxyChain = new ProxyTigerChain(xiaoMing,xiaoqian) ;proxyChain.giveFlowers();proxyChain.writeLoveLetters();proxyChain.buyClothes();proxyChain.doSomthing();}}
上面的代码完美吗？完美个鸟鸟，试想把 Test 比做一个场景：比如是在 KTV，我靠，小明不是害羞吗？竟然也出现在 KTV 中「如果小明能当明看着你帮他追小倩，早就自己动手了」，所以按正常逻辑小明不应该出现在 KTV「Test 中」
/*** Created by TigerChain* 定义一个工厂类，这样就屏蔽了客户端对代理的感知*/public class ZhuimmFactory {public static ZhuimmWay getInstance(String name){return new ProxyTigerChain(new XiaoMing(),new MM(name)) ;}}
嘻嘻，不知不觉又用到以前学到的简单工厂模式了「学以致用，不错不错」，我们把代理事情都放在工厂中去做，这样客户端对代理是无感知的，这也符合程序开发的正常逻辑
public class Test {public static void main(String args[]){// 调用者不知道调用的是代理类还是真实类，这才是正常的逻辑呀ZhuimmWay zhuimmWay = ZhuimmFactory.getInstance("小倩") ;zhuimmWay.giveFlowers();zhuimmWay.writeLoveLetters();zhuimmWay.buyClothes();zhuimmWay.doSomthing();}}
想知道结局吗？很不幸，小倩也有点”白痴”，我提醒好多次是小明喜欢她「其实我最多是代理小明送花等这些事情，也就是说钱花小明的，美女我来追」，可是她最终还是看上我了「有点自恋」，所以以后追 MM 的时候，千万千万不要找代理「以上故事纯属虚构，如有雷同，那么小明以后就张点心吧」

1、使用静态代理完成

根据 UML 撸码
