我创建服务但它不起作用

services:
    redirectionListener:
          class: Front\EcommerceBundle\Listener\RedirectionListener

这是我的课

        $this->session = $session;
        $this->router = $container->get('router');
        $this->securityContext = $container->get('security.context');
    }

    public function onKernelRequest(GetResponseEvent $event)
    {
        $route = $event->getRequest()->attributes->get('_route');

        if ($route == 'livraison' || $route == 'validation') {
            if ($this->session->has('panier')) {
                if (count($this->session->get('panier')) == 0)
                    $event->setResponse(new RedirectResponse($this->router->generate('panier')));
            }

            if (!is_object($this->securityContext->getToken()->getUser())) {
                $this->session->getFlashBag()->add('notification','Vous devez …
