Java--設計模式之代理模式

代理模式，爲其他對象提供一種代理以控制對這個對象的訪問。

下面我們通過追求者向mm送禮物來展現代理模式。

1、代理接口

public interface GiveGift {
	public void giveDolls();
	public void giveFlowers();
	public void giveChocolate();
}

2、追求者

public class Pursuit implements GiveGift{
	private SchoolGirl mm;
	public Pursuit(SchoolGirl mm){
		this.mm = mm;
	}
	@Override
	public void giveDolls() {
		System.out.println(mm.getName());
		
	}

	@Override
	public void giveFlowers() {
		System.out.println(mm.getName());
		
	}

	@Override
	public void giveChocolate() {
		System.out.println(mm.getName());
		
	}
}

3、辣妹子

public class SchoolGirl {

	private String name;

	public String getName() {
		return name;
	}

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

}

4、代理類

public class Proxy implements GiveGift{
	private Pursuit gg;
	public Proxy(SchoolGirl mm){
		gg = new Pursuit(mm);
	}
	@Override
	public void giveDolls() {
		gg.giveDolls();
		
	}

	@Override
	public void giveFlowers() {
		gg.giveFlowers();
		
	}

	@Override
	public void giveChocolate() {
		gg.giveChocolate();
	}

}

5、測試

public class Test {
	public static void main(String[] args) {
		SchoolGirl schoolGirl = new SchoolGirl();
		schoolGirl.setName("辣妹子");
		Proxy proxy = new Proxy(schoolGirl);
		proxy.giveChocolate();
		proxy.giveDolls();
		proxy.giveFlowers();
	}
}
