04代理模式

背景

本博客是照着程杰的《大话设计模式》一书实现的Java代码的版本，再加自己的一点理解

问题

卓贾易追求娇娇的方式是派出自己的好友戴笠

实现该模型的代码逻辑

女孩类

package com.gof.proxy;

/**
 * 功能描述
 *
 * @since 2023-01-17
 */
public class SchoolGirl {
    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

送礼物接口

package com.gof.proxy;

/**
 * 功能描述
 *
 * @since 2023-01-17
 */
public interface GiveGift {
    void givingFlower();

    void givingChocolate();

    void givingDolly();
}

追求者类

package com.gof.proxy;

/**
 * 功能描述
 *
 * @since 2023-01-17
 */
public class Pursuer implements GiveGift {
    private SchoolGirl girl;

    public Pursuer(SchoolGirl girl) {
        this.girl = girl;
    }

    @Override
    public void givingFlower() {
        System.out.println("送花给" + girl.getName());
    }

    @Override
    public void givingChocolate() {
        System.out.println("送巧克力给" + girl.getName());
    }

    @Override
    public void givingDolly() {
        System.out.println("送洋娃娃给" + girl.getName());

    }
}

代理类

package com.gof.proxy;

/**
 * 功能描述
 *
 * @since 2023-01-17
 */
public class Proxy implements GiveGift {
    private Pursuer pursuer;

    public Proxy(Pursuer pursuer) {
        this.pursuer = pursuer;
    }

    @Override
    public void givingFlower() {
        pursuer.givingFlower();
    }

    @Override
    public void givingChocolate() {
        pursuer.givingChocolate();
    }

    @Override
    public void givingDolly() {
        pursuer.givingDolly();
    }
}

客户端

package com.gof.proxy;

/**
 * 功能描述
 *
 * @since 2023-01-17
 */
public class Client {
    public static void main(String[] args) {
        SchoolGirl girl = new SchoolGirl();
        girl.setName("jiaojiao");
        Pursuer zhuojiayi = new Pursuer(girl);
        Proxy daili = new Proxy(zhuojiayi);
        daili.givingChocolate();
        daili.givingDolly();
        daili.givingFlower();
    }
}

个人理解

代理类和真实类应该实现了同一个接口，因为代理实现的时候只是调用真实类的实现
简单理解，后续还需要深入
