Abstract Factory Pattern

抽象工厂（掌握）

一般生产一套产品

何时使用：系统的产品有多于一个的产品族，而系统只消费其中某一族的产品。

关键代码：在一个工厂里聚合多个同类产品。

    

Test

package com.dp.factory.abstractfactory;
/**
 * 抽象工厂-创建型模型，产生一系列产品
 * 例如：海尔工厂给出的整体厨房装修方案或采用格力工厂给出的整体厨房装修方案
 * 产生新的产品品种时改动的地方过多
 * */
public class Test {
	public static void main(String[] args) {
		
		AbstractFactory f = new DefaultFactory();  //只需要换掉工厂就可以换掉一系列产品
		//AbstractFactory f = new MagicFactory();
		Vehicle c = f.createVehicle();   
		c.run();
		Weapon ak = f.createWeapon();
		ak.shoot();
		Food a = f.createFood();
		a.printName();
	}
}
/*
开车
射击
Apple
*/

AbstractFactory

package com.dp.factory.abstractfactory;

public abstract class AbstractFactory {
	public abstract Vehicle createVehicle();
	public abstract Weapon createWeapon();
	public abstract Food createFood();
}

DefaultFactory

package com.dp.factory.abstractfactory;
/**
 * 默认工厂：产生默认的交通工具、武器、食品等产品
 * */

public class DefaultFactory extends AbstractFactory{

	@Override
	public Vehicle createVehicle() {
		return new Car();
	}

	@Override
	public Weapon createWeapon() {
		return new AK47();
	}

	@Override
	public Food createFood() {
		return new Apple();
	}

}

MagicFactory

package com.dp.factory.abstractfactory;
/**
 * 魔法工厂：产生魔法交通工具、武器、食品等产品
 * */
public class MagicFactory extends AbstractFactory{

	@Override
	public Vehicle createVehicle() {
		return new Broom();
	}

	@Override
	public Weapon createWeapon() {
		return new MagicStick();
	}

	@Override
	public Food createFood() {
		return new MushRoom();
	}
	

}

Weapon

package com.dp.factory.abstractfactory;
/**
 * 武器
 * */
public abstract class Weapon {
	public abstract void shoot();
}

AK47

package com.dp.factory.abstractfactory;
/**
 * AK47武器
 * */
public class AK47 extends Weapon{
	public void shoot() {
		System.out.println("射击");
	}
}

MagicStick

package com.dp.factory.abstractfactory;

public class MagicStick extends Weapon{

	@Override
	public void shoot() {
		System.out.println("魔法棒攻击");
	}

}

Food

package com.dp.factory.abstractfactory;
/**
 * 食品
 * */
public abstract class Food {
	public abstract void printName();
}

Apple

package com.dp.factory.abstractfactory;
/**
 * 苹果食品
 * */
public class Apple extends Food{
	public void printName() {
		System.out.println("Apple");
	}
}

MushRoom

package com.dp.factory.abstractfactory;

public class MushRoom extends Food{

	@Override
	public void printName() {
		System.out.println("MushRoom");
	}

}

Vehicle

package com.dp.factory.abstractfactory;
/**
 * 交通工具
 * */
public abstract class Vehicle {
	public abstract void run();
}

Car

package com.dp.factory.abstractfactory;

import java.util.ArrayList;
import java.util.List;
/**
 * 汽车交通工具
 * */
public class Car extends Vehicle{
	
	public void run() {
		System.out.println("开车");
	}
}

Broom

package com.dp.factory.abstractfactory;
/**
 * 魔法扫帚交通工具
 * */
public class Broom extends Vehicle{

	public void run() {
		System.out.println("坐魔法扫帚");

	}

}
