"@Sensio\Bundle\FrameworkExtraBundle\Configuration\Route" in method ... does not exist, or could not be auto-loaded"

i'm upgrading symfony's version from 2.8 to 3.0.9, and after fixing the errors with some library's versions and other problems, i have tried run the command "php bin/console cache:clear" with problems:

C:\inetpub\wwwroot\360forfuture>php bin/console cache:clear

 // Clearing the cache for the dev environment with debug true



  [Symfony\Component\Config\Exception\FileLoaderLoadException]

This is part of my file "DisponibilidadController.php":

namespace H360\ParkingBundle\Controller;

use H360\generalBundle\Tools\Controller360 as Controller;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\JsonResponse;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;
use H360\ParkingBundle\Entity\ParParkingPlazas;
use H360\ParkingBundle\Entity\ParParkingReservas;
use H360\ParkingBundle\Form\GenDisponibilidadParkingType;
use H360\ParkingBundle\Form\GenCrearReservaParkingType;

/**

 */
class DisponibilidadController extends Controller {

    /**
     * @Route("/index", name="disponibilidad_parking_index")
     *   
     * 
     */
    public function indexAction() {

        // Formulario de búsqueda
        $options = array();
        $options['establecimiento'] = $this->IdEstabActual();
        ...

This is part of my file "routing.yml":

parking_disponibilidad:
    resource: "@ParkingBundle/Controller/DisponibilidadController.php"
    prefix:   /disponibilidad
    type:     annotation

So, another thing to keep in mind, is that with the new Symfony's version i have had that enable "sensio_framework_extra" in config.yml... Maybe there is a conflict between RestBundle and this... or the sintax is different now. Any idea?

Finally, i solved the problem. The file "autoload.php" was wrong.
