Container.php第741行中的ReflectionException：Laravel5.1不存在类7

Question

我想在我的网络应用程序中提供自己更改密码的功能，但我发现标题上的错误已解决，所以有人可以帮我解决这个问题吗？

URL：

http://nuatthai.loc/auth/password

路由：

Route::post('auth/password', ['as' => 'auth.postPassword', 'uses' => 'PasswordController@postPassword']);
Route::get('auth/password', ['as' => 'auth.prePassword', 'uses' => 'PasswordController@prePassword']);

控制器：

<?php
namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Validator;
use Mail;
use App\Role;
use App\User;

use App\Http\Controllers\Controller;

class PasswordController extends Controller
{
  use ResourceController;

  public function __construct()
  {
    $this->middleware('role:' . Role::ADMIN + Role::OWNER + Role::MANAGER + Role::ACCOUNTANT);
  }

  protected function validator(array $data)
  {
    return Validator::make($data, [
        'password' => 'required|confirmed|min:8',
    ]);
  }

  private function updateData(Request $request)
  {
    $user = User::find($this::getMyId());
    $user->password = $request->input('password');
    $user->remember_token = str_random(60);
    $user->save();

    return $user;
  }

  public function prePassword()
  {
    return view('auth.change');
  }

  public function postPassword($request)
  {
    $validator = $this->validator($request->all());

    if ($validator->fails()) {
      \Session::flash('flash_error', $validator->messages());
      $this->throwValidationException(
        $request, $validator
      );
    }

    $this::updateData($request);
  }
}

中间件：

use App\UserRole;
class RoleMiddleware
{
    /**

     *

     */
    public function handle($request, Closure $next, $mode)
    {
      if(!\Auth::check()) {
        // session expired.
        return redirect()->guest('auth/login');
      }
      else {
        $admin = $mode & Role::ADMIN;
        $owner = $mode & Role::OWNER;
        $manager = $mode & Role::MANAGER;
        $accountant = $mode & Role::ACCOUNTANT;

        $type = \Auth::user()->role->type;
        if(($admin) && ($type == Role::ADMIN)) {
          return $next($request);
        }
        if(($owner) && ($type == Role::OWNER)) {
          return $next($request);
        }
        if(($manager) && ($type == Role::MANAGER)) {

        }
        if(($accountant) && ($type == Role::ACCOUNTANT)) {
          return $next($request);
        }
        return response('Access Denied.', 403);
      }
    }
}

作用：

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;
use App\Http\Controllers\ResourceController;

class Role extends Model
{
  use ResourceController;
  const TABLE = 'common_roles';
  const ROLE_ID = 'role_id';
  const ROLE_TYPE = 'type';
  const TABLE_ROLE_ID = self::TABLE . '.' . self::ROLE_ID;
  const TABLE_ROLE_TYPE = self::TABLE . '.' . self::ROLE_TYPE;

  protected $table = self::TABLE;
  protected $primaryKey = self::ROLE_ID;

  const ADMIN = 0b1000; // 8
  const OWNER = 0b100; // 4
  const MANAGER = 0b10; // 2
  const ACCOUNTANT = 0b1; // 1

  public function users()
  {
    return $this->hasMany('App\User');
  }
}

我非常感谢您提前提出任何建议和建议。
