我为我的laravel 5.2进行自定义身份验证时收到错误但是此代码在我的laravel 5.1 My config / auth.PHP文件中正常工作

'providers' => [
    'users' => [
        'driver' => 'custom','model' => App\User::class,],// 'users' => [
    //     'driver' => 'database',//     'table' => 'users',// ],

我的CustomUserProvider.PHP(Auth / CustomUserProvider)文件

<?PHP namespace App\Auth;

use Illuminate\Contracts\Auth\UserProvider;
use Illuminate\Contracts\Hashing\Hasher as HasherContract;
use Illuminate\Contracts\Auth\Authenticatable as UserContract;

class CustomUserProvider implements UserProvider {

    protected $model;

    public function __construct(UserContract $model)
    {
        $this->model = $model;
    }

    public function retrieveById($identifier)
    {

    }

    public function retrieveByToken($identifier,$token)
    {

    }

    public function updateRememberToken(UserContract $user,$token)
    {

    }

    public function retrieveByCredentials(array $credentials)
    {

    }

    public function validateCredentials(UserContract $user,array $credentials)
    {

    }

}

我的CustomAuthProvider.PHP文件

<?PHP namespace App\Providers;

use App\User;
use Auth;
use App\Auth\CustomUserProvider;
use Illuminate\Support\ServiceProvider;

class CustomAuthProvider extends ServiceProvider {

    /**
     * Bootstrap the application services.
     *
     * @return void
     */
    public function boot()
    {
        $this->app['auth']->extend('custom',function()
        {

            return new CustomUserProvider();
        });
    }

    /**
     * Register the application services.
     *
     * @return void
     */
    public function register()
    {
        //
    }

}

现在这在laravel 5.1 in 5.2中工作正常我得到的错误就像

InvalidArgumentException in CreatesUserProviders.PHP line 40:
Authentication user provider [custom] is not defined.

$this->app['auth']->provider(...

$this->app['auth']->extend(...
