1.1 角色
AbstractFactory抽象工厂它声明了一组用于创建产品的方法每一个方法对应一种产品。ConcreteFactory具体工厂它实现了在抽象工厂中声明的创建产品的方法生成一组具体产品这些产品构成了一个产品族每一个产品都位于某个产品等级结构中。AbstractProduct抽象产品它为每种产品声明接口在抽象产品中声明了产品所具有的业务方法。ConcreteProduct具体产品它定义具体工厂生产的具体产品对象实现抽象产品接口中声明的业务方法。

2.1 设计
定义抽象产品A 定义具体产品A-1 它有Name、Weight两个成员它的SetName()、SetWeight()两个方法分别负责设置以上两个成员它的Get()方法获取它本身的信息 定义具体产品A-2 它有Name、Weight两个成员它的SetName()、SetWeight()两个方法分别负责设置以上两个成员它的Get()方法获取它本身的信息 定义抽象产品B 定义具体产品B-1 它有Name、Height两个成员它的SetName()、SetHeight()两个方法分别负责设置以上两个成员它的Get()方法获取它本身的信息 定义具体产品B-2 它有Name、Height两个成员它的SetName()、SetHeight()两个方法分别负责设置以上两个成员它的Get()方法获取它本身的信息 定义抽象工厂 定义具体工厂1 它的方法SetProductA()设置具体产品A-1它的方法SetProductB()设置具体产品B-1 定义具体工厂2 它的方法SetProductA()设置具体产品A-2它的方法SetProductB()设置具体产品B-2 定义一个函数CreateFactory()用来创建具体工厂调用 用CreateFactory()函数实例化 具体工厂1——factory1用factory1实例化产品A-1和产品B-1并查看结果用CreateFactory()函数实例化 具体工厂2——factory2用factory2实例化产品A-2和产品B-2并查看结果
