我正在Laravel5.8中构建一个带有内置认证系统的CMS。我的应用程序工作正常，但突然它开始给我一个错误，因为ReflectionException:Class app\Http\Controllers\Users在命令php artisan route:list-v上不存在。但是，如果我定义了一个新的资源路由，那么新的路由页面工作正常。这意味着，正在保存路由文件，但在列出路由时出错。

我没有创建任何名为Users的文件，但我的用户控制器文件名为UserController

以下是我的申请结构：

cms -> project folder
  app
    Http
      Controllers
        Auth
          RegisterController.php
          LoginController.php and other Auth files
        backend
          UserController.php and my other controller files

下面是我的路线文件

Auth::routes();

Route::group(['as'=>'cms.'  ,'prefix'=>'cms'],function(){
    Route::get('/', 'backend\Dashboard@index')->name('dashboard');
    Route::resource('/user-management', 'backend\UserController');
});

下面是驻留在后端文件夹中的我的UserController文件

        }       
    }
}

我尝试了以下命令，它们都成功运行，但没有一个解决了错误

php artisan clear-compiled
composer dump-autoload 
php artisan optimize 
php artisan route:cache

不知道从何处引用此用户控制器类。

在这方面，有人能帮我吗？我的发展陷入了困境。

多谢各位，
