基于Go实现设计模式中的工厂模式

话不多说开干

package main

import "fmt"

// 定义接口
type People interface {
	DoWork()
}

// 学生
type Student struct {
}

func (r *Student) DoWork() {
    fmt.Println("study");
}

// 程序员
type Programmer struct {

}

func (r *Programmer) DoWork() {
	fmt.Println("touch fish");
}

// 工厂
type PeopleFactory struct {

}

func (r *PeopleFactory) GetPeople(username string) People {
	if username == "尤雨溪" {
        return new(Programmer)
	} else {
		return new(Student)
	}
}

func main() {
	peopleFactory := new(PeopleFactory)
	peopleFactory.GetPeople("尤雨溪").DoWork()
	peopleFactory.GetPeople("Field").DoWork()
}
