对静态代理模式的初步理解

package demo1;
 
public class StaticProxy {
    public static void main(String[] args) {
        new Thread(()-> System.out.println("我爱你")).start();
        MarryCompany marryCompany = new MarryCompany(new You());
        marryCompany.HappyMarry();
    }
}
 
interface Marry {
    void HappyMarry();
}
 
class You implements Marry{
    @Override
    public void HappyMarry() {
        System.out.println("我结婚啦，超开心");
    }
}
 
class MarryCompany implements Marry{
    You target;//创建一个you对象
 
    public MarryCompany(You target) {
        this.target = target;
    }
 
    @Override
    public void HappyMarry() {
        before();
        target.HappyMarry();
        after();
 
    }
 
    private void after() {
        System.out.println("结婚后，含泪缴费");
    }
 
    private void before() {
        System.out.println("结婚前，准备工作");
    }
}

静态代理模式,相当于创建一个或多个功能少的实现类和一个功能多的实现类,两个类实现同一个接口,将少功能类传入多功能类,在多功能类中调用自身方法和少功能方法
