Types

type Human

type Human interface {
	Eat()
	Play()
}

简单工厂的模式的话就不需要这个接口了 定义人类接口

type HumanFactory

type HumanFactory struct {
}

func (*HumanFactory) CreateWhite

func (factory *HumanFactory) CreateWhite() Human

func (*HumanFactory) CreateYellow

func (factory *HumanFactory) CreateYellow() Human

type HumanFactoryInf

type HumanFactoryInf interface {
	CreateWhite() Human
	CreateYellow() Human
}

缺点：当需要增加创建black时则代码改动很大 优点：可以控制创建产品的关系，我们可以将CreatWhite和CreatYellow内置，然后对外提供Create限制CreatWhite和CreatYellow关系
