是否可以在Symfony2中动态注册bundle？

// src/AppBundle/EventListener/DynamicBundleListener.php
namespace AppBundle\EventListener;

use Symfony\Component\HttpKernel\KernelEvents;
use Symfony\Component\HttpKernel\Event\GetResponseEvent;

class DynamicBundleListener
{
    private $bundles;

    public function __construct(array $bundles)
    {
        $this->bundles = $bundles;
    }

    public function onKernelRequest(GetResponseEvent $event)
    {
        $kernel = $event->getKernel();
        $request = $event->getRequest();

        // 根据请求参数或其他条件动态决定要注册的bundle
        $dynamicBundles = $this->getDynamicBundles($request);

        foreach ($dynamicBundles as $bundle) {
            if (!in_array($bundle, $kernel->getBundles())) {
                $kernel->registerBundle($bundle);
            }
        }
    }

    private function getDynamicBundles($request)
    {
        // 根据请求信息返回要注册的bundle列表
        // 您可以根据需要实现此方法
        return [];
    }
}

# app/config/services.yml
services:
    app.dynamic_bundle_listener:
        class: AppBundle\EventListener\DynamicBundleListener
        arguments:
            - !tagged app.dynamic_bundle
        tags:
            - { name: kernel.event_listener, event: kernel.request, method: onKernelRequest }
