Php 注册确认监听器&；FOSUserBundle

我尝试在使用侦听器注册后将新用户重定向到欢迎页面。但我没有结果。我确实喜欢那一页上写的。请帮忙。代码如下：

namespace Acme\UserBundle\EventListener;

use FOS\UserBundle\Event\GetResponseUserEvent;
use FOS\UserBundle\FOSUserEvents;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\Routing\Generator\UrlGeneratorInterface;

/**
 * Listener responsible to change the redirection at the end of the password resetting
 */
class RegistrationConfirmListener implements EventSubscriberInterface
{
    private $router;

    public function __construct(UrlGeneratorInterface $router)
    {
        $this->router = $router;
    }

    /**
     * {@inheritDoc}
     */
    public static function getSubscribedEvents()
    {
        return array(
            FOSUserEvents::REGISTRATION_CONFIRM => 'onRegistrationConfirm'
        );
    }

    public function onRegistrationConfirm(GetResponseUserEvent $event)
    {
        $url = $this->router->generate('_welcome');

        $event->setResponse(new RedirectResponse($url));
    }
}

我的服务：

<service id="acme_user.registration.confirmed" class="Acme\UserBundle\EventListener\RegistrationConfirmListener">
        <tag name="kernel.event_subscriber"/>
        <argument type="service" id="router"/>
    </service>

我只需要使用

注册\u SUCCESS

来代替

注册\u CONFIRM

。一切都好
