疾速开始
```
$ bee new myproj
$ cd myproj && bee run

一般路由

$ vi ./myproj/routers/router.go

package routers

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

func init() {beego.Router("/", &controllers.MainController{})
    beego.Router("/hello", &controllers.MainController{}) // 新增一条路由 /hello
}

$ curl http://127.0.0.1:8080/hello       
<!DOCTYPE html>

<html>
<head>
  <title>Beego</title>
  <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
  ........

namespace 路由

// ./myproj/routers/router.go
package routers

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

func init() {beego.Router("/", &controllers.MainController{})
    // 一般路由
    beego.Router("/hello", &controllers.MainController{})
    
    // namespace 路由  
    ns := beego.NewNamespace("/api",
        beego.NSRouter("/hello1", &controllers.MainController{}),
        beego.NSRouter("/hello2", &controllers.MainController{}),
    )
    beego.AddNamespace(ns)
}

$ curl http://127.0.0.1:8080/api/hello1

重写 MainController 的 Get 办法

// ./myproj/controllers/default.go
package controllers

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

type MainController struct {beego.Controller}

func (c *MainController) Get() {// c.Data["Website"] = "beego.me"
    // c.Data["Email"] = "[email protected]"
    // c.TplName = "index.tpl"

    ret := map[string]string{"data": "hello golang!",}
    c.Data["json"] = ret
    c.ServeJSON()}

$ curl http://127.0.0.1:8080/hello
{"data": "hello golang!"}

根本流程

 建设 Model 相干的 struct
应用 orm.RegisterModel 注册定义的 Model
应用 orm.RefisterDriver 函数注册数据库驱动
应用 orm.RegisterDataBase 函数绑定相干的数据库
应用 orm.Debug 开启 ORM 调试模式（开发过程能够关上，release 须要敞开）
