go - 接口(interface)中的动态返回类型

Question

有以下代码:

UserModel.go

type UserModel struct{login, password}
var EntityArr = map[string]UserModel{}
func GetAll() map[string]UserModel {
    uuidString := uuid.New().String()
    user := Entity{Login: "myLogin", Password: "MyPassword"}
    EntityArr[uuidString] = user

    return EntityArr
}

PostModel.go

type PostModel struct{title, description}
func GetAll() map[string]PostModel {/* like in UserModel */}

UserController.go

type ControllerUser struct{}
func GetAll()map[string]UserModel { rertun UserModel.GetAll() } 

PostController.go

type ControllerPost struct{}
func GetAll()map[string]PostModel { rertun PostModel.GetAll() }

我尝试动态检测必要的 Controller :

main.go

var currentController = Intfc
switch entity {
  "user" : currentController = UserController.ControllerUser{}
  "post" : currentController = PostController.ControllerPost{}
}
currentController.GetAll()

为此，我需要一个通用接口(interface)

接口(interface).go

type Intfc interface {
    ShowAll() ???
}

函数(在接口(interface)中)返回什么类型的返回数据？
