Router Annotations in Micro

router.php

use Phalcon\Mvc\Router\Annotations as RouterAnnotations;

$routerA = new RouterAnnotations(false);
$routerA->addResource('Conf', '/conf');
$app->setService('router', $routerA, true);

ConfController.php

/**
 * @RoutePrefix('/conf')
 */
class ConfController extends Phalcon\Mvc\Controller
{
    /**
     * @Get('/')
     */
    public function indexAction()
    {
        //$this->assets->addJs('js/jquery.js');
        echo ('ConfController');
        d($this->view);
        $this->view->render(get_class(), 'indexAction', array());
    }

}

index.php

  // Initializing application
  $app = new \Phalcon\Mvc\Micro();

  // Setting DI container
  $app->setDI($di);

    // Processing request 
  $app->handle();

And i am getting "Matched route doesn't have an associated handler"

if I dump $app after handle() i see all members begining with _ are empty

_handles must not be empty https://github.com/phalcon/cphalcon/blob/master/phalcon/mvc/micro.zep

            let matchedRoute = router->getMatchedRoute();
            if typeof matchedRoute == "object" {

                if !fetch handler, this->_handlers[matchedRoute->getRouteId()] {
                    throw new Exception("Matched route doesn't have an associated handler");
                }

What is wrong? How to populate _handle? Annotations are usable in Micro or in Full/MVC only
