golang中的类和接口的使用

类使用:实现一个people中有一个sayhi的方法调用功能,代码如下:

type People struct {
	//..
}

func (p *People) SayHi() {
	fmt.Println("************************* say hi !!")
}

func (this *LoginController) Get() {
	p := new(People)
	p.SayHi()

	this.TplName = "login.html"
}

接口使用:实现上面功能,代码如下:

type People struct {
	//..
}

func (p *People) SayHi() {
	fmt.Println("************************* say hi !!")
}

type IPeople interface {
	SayHi()
}

func (this *LoginController) Get() {
	var p IPeople = new(People)
	p.SayHi()

	this.TplName = "login.html"
}
