设计模式之静态代理模式

Posted 2021-01-15 yjxs

多线程里的Runnable接口创建线程正是用了静态代理模式
package Tread;

public class StaticProxy {
	/**
	 * 静态代理： 真实角色 
                    代理角色 两者要实现相同接口
	 * 
	 * @param args
	 */
	public static void main(String[] args) {
		You you = new You();
		WeddingCompany wc = new WeddingCompany(you);
		wc.marry();
	}
}
	interface Marry {
		public abstract void marry();
	}

class You implements Marry {
		@Override
		public void marry() {
			System.out.println("你和嫦娥结婚");

		}

	}

class WeddingCompany implements Marry {
		private Marry you;

		public WeddingCompany() {
			super();
		}
		public WeddingCompany(You you) {
			this.you = you;
		}



		public void before() {
			System.out.println("布置猪窝");
		}

		public void after() {
			System.out.println("闹玉兔");
		}
		@Override
		public void marry() {
			before();
			you.marry();
			after();
		}

	}

　　示例如下

package Tread;

public class Thread03 implements Runnable {

	@Override
	public void run() {
		for (int i = 0; i < 1000; i++) {
			System.out.println("一边敲代码");
		}

	}

}
package Tread;

public class Thread03App {
	public static void main(String[] args) {
		Thread03 t = new Thread03();(真实角色)
		Thread proxy = new Thread(t);
		proxy.start();
		for (int i = 0; i < 1000; i++) {
			System.out.println("一边聊qq");
		}
	}
}
