模型不在phalcon多模块上加载

$loader = new \Phalcon\Loader();

$loader->registerNamespaces([
    'App\Modules\A\Models' => APP_PATH . '/modules/A/models/',
]);

$loader->register();

namespace App\Modules\A\Models;

use Phalcon\Mvc\Model;

class UserModel extends Model
{
    // 模型的定义
}

namespace App\Modules\A\Controllers;

use App\Modules\A\Models\UserModel;

class UserController extends ControllerBase
{
    public function indexAction()
    {
        $users = UserModel::find();
        // 其他操作
    }
}
