直接上代码

package com.example.multi_thread;

public class StaticProxy {
    public static void main(String[] args) {
        new WeddingCompany(new You()).happyWedding();// new Thread(()->System.out.println("aaa")).start() 对照理解静态代理模式
    }
}

interface Marry {
    void happyWedding();
}

class You implements Marry {
    @Override
    public void happyWedding() {
        System.out.println("结婚啦，超开心");
    }
}

class WeddingCompany implements Marry {
    private You target;

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

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


    }

    private void after() {
        System.out.println("收尾款");
    }

    private void before() {
        System.out.println("布置婚礼现场");
    }
}
