PHP致命错误：未捕获错误：在Controller中的加载模型中找不到类

我有这个MVC文件夹结构：

application
-----------catalog
------------------controller
----------------------------ProfileContoller.php
------------------model
----------------------------UserModel.php
------------------view
------------------language
-----------admin
------------------controller
------------------model
------------------view
------------------language
core
---- Controller.php
public
vendor
....

现在在ProfileController.php我有：

namespace Application\Catalog\Controller;

use Application\Core\Controller as Controller;

use Application\Core\Model\UserModel;

class ProfileController extends Controller
{
    /**
     * Construct this object by extending the basic Controller class
     */
    public function __construct()
    {
        parent::__construct();
    }

    /**
     * This method controls what happens when you move to /overview/index in your app.
     * Shows a list of all users.
     */
    public function index()
    {
        $this->View->render('profile/index','', array(
            'users' => UserModel::getPublicProfilesOfAllUsers())
        );
    }

}

在UserModel.php我有：

namespace Application\Catalog\Model;

class UserModel
{

    public static function getPublicProfilesOfAllUsers()
    {
        $database = DatabaseFactory::getFactory()->getConnection();

        $sql = "SELECT user_id, user_name, user_email, user_active, user_has_avatar, user_deleted FROM users";
        $query = $database->prepare($sql);
        $query->execute();

        $all_users_profiles = array();

        foreach ($query->fetchAll() as $user) {

            array_walk_recursive($user, 'Filter::XSSFilter');

            $all_users_profiles[$user->user_id] = new stdClass();
            $all_users_profiles[$user->user_id]->user_id = $user->user_id;
            $all_users_profiles[$user->user_id]->user_name = $user->user_name;
            $all_users_profiles[$user->user_id]->user_email = $user->user_email;
            $all_users_profiles[$user->user_id]->user_active = $user->user_active;
            $all_users_profiles[$user->user_id]->user_deleted = $user->user_deleted;
            $all_users_profiles[$user->user_id]->user_avatar_link = (Config::get('USE_GRAVATAR') ? AvatarModel::getGravatarLinkByEmail($user->user_email) : AvatarModel::getPublicAvatarFilePathOfUser($user->user_has_avatar, $user->user_id));
        }

        return $all_users_profiles;
    }

使用Composer Psr4我使用以下自动加载文件：

"autoload": {
        "psr-4": { "Application\\": "application/","Application\\Core\\": "application/core/","Application\\Catalog\\Model\\": "application/catalog/model/"}
    }
    }

现在，当我需要路由我的Url时，我会采取行动：

$route->get('/cms/profile/index/', 'Application\Catalog\Controller\ProfileController@index');

我看到这个错误：
