类& # 39;应用验证器# 39;没有找到laravel

请帮助我在laravel 5.1中创建登录和注册页面时获得此错误

FatalErrorException in AuthController.php line 44:
Class 'App'Validator' not found

这是我的AuthController.php

<?php
namespace App'Http'Controllers'Auth;
use App'User;
use App'Validator;
use App'Http'Controllers'Controller;
use Illuminate'Foundation'Auth'ThrottlesLogins;
use Illuminate'Foundation'Auth'AuthenticatesAndRegistersUsers;
class AuthController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Registration & Login Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles the registration of new users, as well as the
    | authentication of existing users. By default, this controller uses
    | a simple trait to add these behaviors. Why don't you explore it?
    |
    */
    use AuthenticatesAndRegistersUsers, ThrottlesLogins;
    /**
     * Create a new authentication controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest', ['except' => 'getLogout']);
    }
    /**
     * Get a validator for an incoming registration request.
     *
     * @param  array  $data
     * @return 'Illuminate'Contracts'Validation'Validator
     */
    protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => 'required|max:255',
            'email' => 'required|email|max:255|unique:users',
            'password' => 'required|confirmed|min:6',
        ]);
    }
    /**
     * Create a new user instance after a valid registration.
     *
     * @param  array  $data
     * @return User
     */
    protected function create(array $data)
    {
        return User::create([
            'name' => $data['name'],
            'email' => $data['email'],
            'password' => bcrypt($data['password']),
        ]);
    }
}

和我的注册视图

<!-- resources/views/auth/register.blade.php -->
<form method="POST" action="/QADapps/auth/register">
    {!! csrf_field() !!}
    <div>
        Name
        <input type="text" name="name" value="{{ old('name') }}">
    </div>
    <div>
        Email
        <input type="email" name="email" value="{{ old('email') }}">
    </div>
    <div>
        Password
        <input type="password" name="password">
    </div>
    <div>
        Confirm Password
        <input type="password" name="password_confirmation">
    </div>
    <div>
        <button type="submit">Register</button>
    </div>
</form>

所有的代码都来自laravel文档。这就是为什么我不知道为什么它失败了。请检查我在哪里得到错误。谢谢你

这也是我的路由控制器

// Authentication routes...
Route::get('auth/login', 'Auth'AuthController@getLogin');
Route::post('auth/login', 'Auth'AuthController@postLogin');
Route::get('auth/logout', 'Auth'AuthController@getLogout');
// Registration routes...
Route::get('auth/register', 'Auth'AuthController@getRegister');
Route::post('auth/register', 'Auth'AuthController@postRegister');

注:我的应用程序属于http://localhost:8080/QADapps/auth/register这有什么问题吗?我还将index.php和.htaccess从public移到根目录
