类App\Policies\StatusPolicy不存在

Question

我设置了类，以便可以使用Laravel Authorization和策略特性。但是在为我的方法定义中间件时，我一直收到这个错误(Class App\Policies\StatusPolicy不存在)。这就是我所拥有的：

AuthServiceProvider.php

namespace App\Providers;

use Illuminate\Support\Facades\Gate;
use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider;

class AuthServiceProvider extends ServiceProvider
{
    /**
     * The policy mappings for the application.
     *
     * @var array
     */
    protected $policies = [
        'App\Status' => 'App\Policies\StatusPolicy',
    ];

    /**
     * Register any authentication / authorization services.
     *
     * @return void
     */
    public function boot()
    {
        $this->registerPolicies();

        //
    }
}

StatusController.php

namespace App\Http\Controllers;

use App\Status;
use Illuminate\Http\Request;

class StatusController extends Controller
{

    public function __construct()
    {
         $this->middleware('can:list,App\Status')->only('index');
         $this->middleware('can:update,status')->only('edit');
    }

    // ...

状态(由php artisan make生成:policy StatusPolicy -- StatusPolicy.php =Status

namespace Policies;

use App\User;
use App\Status;
use Illuminate\Auth\Access\HandlesAuthorization;

class StatusPolicy
{
    use HandlesAuthorization;

    /**
     * Verifica se o usuário tem permissão para listar os status.
     *
     * @param  \App\User  $user
     * @return bool
     */
    public function list(User $user)
    {
        return true;
    }

    /**
     * Determine whether the user can view the status.
     *
     * @param  \App\User  $user
     * @param  \App\Status  $status
     * @return mixed
     */
    public function view(User $user, Status $status)
    {
        //
    }

    /**
     * Determine whether the user can create statuses.
     *
     * @param  \App\User  $user
     * @return mixed
     */
    public function create(User $user)
    {
        //
    }

    /**
     * Determine whether the user can update the status.
     *
     * @param  \App\User  $user
     * @param  \App\Status  $status
     * @return mixed
     */
    public function update(User $user, Status $status)
    {
        return true;
    }

    /**
     * Determine whether the user can delete the status.
     *
     * @param  \App\User  $user
     * @param  \App\Status  $status
     * @return mixed
     */
    public function delete(User $user, Status $status)
    {
        //
    }
}
