beego注解路由

按照beego官方文档 注解路由 尝试写的路由，但是确实报错的：goland提示：unresolved type CMSController cms.go中的代码

package controllers

import (
    "github.com/astaxie/beego"
)

// CMSController operations for CMS
type CMSController struct {
    beego.Controller
}

// URLMapping ...
func (c *CMSController) URLMapping() {
    c.Mapping("StaticBlock", c.StaticBlock)
    c.Mapping("AllBlock", c.AllBlock)
}

// @router /staticblock/:key [get]
func (this *CMSController) StaticBlock() {

}

// @router /all/:key [get]
func (this *CMSController) AllBlock() {

}

router.go中的代码：

package routers

import (
    "quickstart/controllers"
    "github.com/astaxie/beego"
    "github.com/astaxie/beego/context"
)

func init() {
    beego.Router("/", &controllers.MainController{})
    beego.Get("/base", func(ctx *context.Context) {
        ctx.Output.Body([]byte("hello world"))
    })

    beego.Post("/alice", func(ctx *context.Context) {
        ctx.Output.Body([]byte("bob"))
    })

    beego.Any("/foo", func(ctx *context.Context) {
        ctx.Output.Body([]byte("bar"))
    })

    beego.Include(&CMSController{})
}

完全照抄beego这节内容的代码，但是还是报这个错误 bee run 的时候，也报错：

routers/router.go:23:17: undefined: CMSController
2018/04/08 23:12:08 ERROR    ▶ 0003 Failed to build the application: # quickstart/routers
routers/router.go:23:17: undefined: CMSController

请问这个错误，应该怎么解决？ 还是说，注解路由只支持API类的项目？
