How to handle exceptions for a specific controller in symfony 2

Question

I have a controller that processes API requests. Now I need to handle any exceptions for this controller separately, that is, convert to json / xml format, redefine the message or add any details. Exception handling all over the world is not suitable in my case.

Today I have a KernelEvent subscriber that handles kernel.exception and detects the current controller ( Gist ):

public function processApiException(GetResponseForExceptionEvent $event)
{
    $controllerName = $this->container->get('controller_name_converter');
    $resolver = new ControllerResolver($this->container, controllerName);
    $controller = $resolver->getController($event->getRequest());

    if ($contoller && $controller[0] instanceof JsonApiControllerInterface) {
        $this->handleApiExceptionEvent($event);
    }
}

So the questions are:

• Is this a good solution to handle specific controller exceptions this way?
• Is there any other method to get the current controller (from GetResponseForExceptionEvent) other than using ControllerResolver?
