抽象工厂模式——工厂的工厂

### **抽象工厂模式：** ###

围绕一个超级工厂创建其他工厂，该超级工厂又称为其他工厂的工厂。

### **定义：** ###

抽象工厂模式提供了一个创建一系列相关或者依赖对象的接口，无需指定他们具体的类。

**同一产品族的东西都是由同一个工厂生产的，但同一产品族位于不同等级结构**

**产品等级数量相对固定的一些产品族 可以考虑使用抽象模式**

--------------------

**先写两个产品：手机、路由器。**

**再写两个产品的实现：小米、华为手机，小米、华为路由器。**

**然后定义一个抽象工厂，该工厂可能实现路由器也可能实现手机。**

手机抽象接口： IphoneProduct

//手机产品接口
    public interface IphoneProduct{
    	void start();
        void shutdown();
        void callup();
        void sendSMS();
    }

抽象路由器接口： IRouterProduct

//路由器产品接口
    public interface IRouterProduct{
    	void start();
        void shutdown();
        void openWifi();
        void setting();
    }

小米手机： XiaomiPhone

public class XiaomiPhone implements IphoneProduct{
    	public void start(){
        	Sysout.out.println("xm kaiji");
        }
        public void shutdown(){
            Sysout.out.println("xm guanji");
        }
        public void callup(){
            Sysout.out.println("xm dadianhua");
        }
        public void sendSMS(){
            Sysout.out.println("xm faduanxin");
        }
    }

华为手机：HuaweiPhone

public class HuaweiPhone implements IphoneProduct{
    	public void start(){
        	Sysout.out.println("hw kaiji");
        }
        public void shutdown(){
            Sysout.out.println("hw guanji");
        }
        public void callup(){
            Sysout.out.println("hw dadianhua");
        }
        public void sendSMS(){
            Sysout.out.println("hw faduanxin");
        }
    }

小米路由器： XiaomiRouter

public class XiaomiRouter implements IRouterProduct{
    	public void start(){
        	Sysout.out.println("xm kaiji");
        }
        public void shutdown(){
            Sysout.out.println("xm guanji");
        }
        public void openWifi(){
            Sysout.out.println("xm dakaiwifi");
        }
        public void setting(){
            Sysout.out.println("xm shezhi");
        }
    }

华为路由器： HuaweiRouter

public class HuaweiRouter implements IRouterProduct{
    	public void start(){
        	Sysout.out.println("hw kaiji");
        }
        public void shutdown(){
            Sysout.out.println("hw guanji");
        }
        public void openWifi(){
            Sysout.out.println("hw dakaiwifi");
        }
        public void setting(){
            Sysout.out.println("hw shezhi");
        }
    }

抽象产品工厂：IProductFactory

public class IProductFactory{
    	//生产手机
        	IPhoneProduct iphoneProduct();
        //生产路由器
        	IPouterProduct routerProduct();
    }

小米工厂：XiaomiFactory

public class XiaomiFactory implements IProductFactory{
    	public IPhoneProduct iphoneProduct(){
        	return new XiaomiPhone();
        }
        public IRouterProduct routerProduct(){
        	return new XiaomiRouter();
        }
    }

华为工厂：HuaweiFactory

public class XiaomiFactory implements IProductFactory{
    	public IPhoneProduct iphoneProduct(){
        	return new HuaweiPhone();
        }
        public IRouterProduct routerProduct(){
        	return new HuaweiRouter();
        }
    }

实现：Client

public class Client{
    	...main(...){
        	//小米工厂
            XiaomiFactory xiaomiFactory = new XiaomiFactory();
            
            IPhoneProduct iphoneProduct = xiaomiFactory.iphoneProduct();
            iphoneProduct.callup();
            iphoneProduct.sendSMS();
            
            IRouterProduct iRouterProduct = xiaomiFactory.routerProduct();
            iRouterProduct.openWifi();
            //华为同理Xiaomi->Huawei
            HuaweiFactory huaweiFactory = new HuaweiFactory();
            
            IPhoneProduct iphoneProduct = huaweiFactory.iphoneProduct();
            iphoneProduct.callup();
            iphoneProduct.sendSMS();
        }
    }
