答
听 kernel.request 并使用 $request->getPathInfo() 查询路线数据库.如果找到，请在请求上设置 _controller 属性.
Listen to kernel.request and use the $request->getPathInfo() to query the database for a route. If you find one, set the _controller attribute on the request.
$request->attributes->set('_controller', $row['controller']);
如果您正在运行 master 分支(Symfony 2.1)，您的监听器的优先级将需要大于 32，以便在路由器之前运行.
If you are running the master branch (Symfony 2.1) your listener will need to have a priority greater than 32 so it will run before the router.
