设计模式之（二）---代理模式Proxy Pattern

package com.fc.Proxy;
public interface KindWoman {
	public void makeEyesWithMan(); //抛媚眼
}

package com.fc.Proxy;

public class PanJinlian implements KindWoman {

	public void makeEyesWithMan() {
		System.out.println("潘金莲在抛媚眼。。。");

	}

}

再来个王婆，也就是潘金莲的代理人：

package com.fc.Proxy;

public class WangPo implements KindWoman {
private KindWoman kindwoman;


	public WangPo() {
		this. kindwoman = new PanJinlian();//王婆默认是潘金莲的代理人
}
	//王婆也可以是KindWomen的其他任何一个女人的代理，只要你是这一类型
	public WangPo(KindWoman kindWomen){
	 this. kindwoman = kindWomen;
	 }

	public void makeEyesWithMan() {
		 this. kindwoman.makeEyesWithMan(); //王婆这么大年龄了，谁看她抛媚眼？！她代替别人抛
		 }

}

package com.fc.Proxy;

public class XiMenQing {

	
	public static void main(String[] args) {
		//把王婆叫出来
		 WangPo wangPo = new WangPo();
		 //然后西门庆就说，我要和潘金莲happy，然后王婆就安排了西门庆丢筷子的那出戏:
		 wangPo.makeEyesWithMan(); //看到没，虽然表面上时王婆在做，实际上爽的是潘金莲

	}

}

package com.fc.Proxy;

public class PanJinlian222 implements KindWoman {

	public void makeEyesWithMan() {
		System.out.println("潘金莲222在抛媚眼。。。");

	}


}

package com.fc.Proxy;

public class XiMenQing {

	
	public static void main(String[] args) {
	/*	//把王婆叫出来
		 WangPo wangPo = new WangPo();
	
		 //然后西门庆就说，我要和潘金莲happy，然后王婆就安排了西门庆丢筷子的那出戏:
		 wangPo.makeEyesWithMan(); //看到没，虽然表面上时王婆在做，实际上爽的是潘金莲
*/	
		WangPo wangPo=new WangPo(new PanJinlian222());//这个不是默认代理，要往里传个参数
		wangPo.makeEyesWithMan();
	}

}
