Posted 2020-10-25 xiaofei001

1.静态代理实现要求

1. 有真实的角色
2. 有代理的对象
3. 真实角色和代理对象实现同一个代理接口

2.静态代理事例

MarrayContent代理MarryPerson,MarryPerson只关注结婚其他事情都交给MarrayContent代理对象去做

public class StaticProxy {
   public static void main(String args[]){
       MarryPerson person = new MarryPerson();
       Marray content = new MarrayContent(person);
       content.marray();
   }
}

//代理接口
interface Marray{
    void marray();
}
//真实角色
class MarryPerson implements Marray{
    @Override
    public void marray() {
        System.err.println("结婚");
    }
}
//代理对象
class MarrayContent implements Marray{
    private MarryPerson marryPerson;
    public MarrayContent(MarryPerson marryPerson){
        this.marryPerson =marryPerson;
    }
    private void searchTarget(){
        System.err.println("寻找合适对象！");
    }

    private void detail(){
        System.err.println("婚后处理！");
    }
    @Override
    public void marray() {
        searchTarget();
        marryPerson.marray();
        detail();
    }
}
