静态代理

以结婚为例子

package com.hao.Demo01;

public class StaticProxy {
    public static void main(String[] args) {

        new Thread( ()-> System.out.println("i love you.")).start();
        new WeddingCompany(new You()).HappyMarry();
    }

}

interface Marry{
    void HappyMarry();
}
//真实角色,你结婚
class You implements Marry{
    @Override
    public void HappyMarry() {
        System.out.println("你要结婚了，HappyMarry");
    }
}
//代理角色，帮你结婚
class WeddingCompany implements Marry{

    private Marry target;

    public WeddingCompany(Marry target) {
        this.target = target;
    }

    @Override
    public void HappyMarry() {
        before();
        this.target.HappyMarry();
        after();

    }

    private void before() {
        System.out.println("结婚前，布置现场");

    }

    private void after() {
        System.out.println("结婚后，收尾款！！！");
    }
}
