lumen框架Controllers文件夹下注册路由异常

1. lumen Controllers结构

    Controllers
         --Test
             --TestController.php

2.注册路由

$app->get("test",'Test\TestController@est');

3.lumen报错；

    lumen.ERROR: ReflectionException: Class App\Http\Controllers\Test\TestController does not exist in /Users/shumingjian/Desktop/www/lumen/vendor/illuminate/container/Container.php:734

4.Testcontroller代码：

    <?php

namespace AppHttpControllersTest;

use AppHttpControllersController as Controller;

class TestController extends Controller{

public function test(){
