Java静态代理模式实例+多线程实现

public class StaticProxy{
    public static void main(String[] args) {
        WeddingCompany weddingCompany = new WeddingCompany(new You());
        weddingCompany.HappyMarry();
    }


}
interface Marry {
    void HappyMarry();
}
//真实所在
class You implements Marry{

    @Override
    public void HappyMarry() {
        System.out.println("人防喜事精神爽");
    }
}
//代理，帮助
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 after() {
        System.out.println("催钱");
    }

    private void before() {
        System.out.println("忙一场");
    }

}
静态代理：
特点：真实对象与代理对象都只是实现同一个接口
　　　代理对象需要代理真实的对象
好处就是：代理对象可以做额外的事情，真实对象不需要做其他乱七八糟的事情，专注与自己的事情
以下为多线程下的静态代理

package com.defend.demo3;

public class StaticProxy{
    public static void main(String[] args) {
        new Thread( () -> System.out.println("时间证明一切")).start();
        new WeddingCompany(new You()).HappyMarry();
    }


}
interface Marry {
    void HappyMarry();
}
//真实所在
class You implements Marry{

    @Override
    public void HappyMarry() {
        System.out.println("人防喜事精神爽");
    }
}
//代理，帮助
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 after() {
        System.out.println("催钱");
    }

    private void before() {
        System.out.println("忙一场");
    }

}
