Symfony - Check if controller exists

My situation: I have a NavigatorController which is triggered by AJAX requests, and will

$this->forward("controllername")

the request. But how can I check if the controller exists based on controller name? Of course, BEFORE the actual forward happens and throws an error when the page controller does not exists.

Also You can check by using Service:

namespace AppBundle\Service;

class ExampleService
{
    /**
     * @param string $controller
     * @return bool
     */
    public function has($controller)
    {
        list($class, $action) = explode('::', $controller, 2);
        return class_exists($class);
    }
}

In app/config/services.yml :

services:
    app.controller.check:
        class: AppBundle\Service\ExampleService

In Controller:

public function indexAction(Request $request)
{
    $controller = 'AppBundle\Controller\DefaultController';
    if($this->get('app.controller.check')->has($controller))
    {
        echo 'Exists';
    }
    else
    {
        echo "Doesn't exists";
    }
}

You can actually use the controller_resolver service that Symfony uses in order to check if controller exists.

public function indexAction(Request $request)
{
    $request->attributes->set('_controller', 'AppBundle\Controller\ExampleController::exampleAction');
    try{
        $this->get('debug.controller_resolver')->getController($request);
    } catch (\Exception $e) {
        $x = $e->getCode();
    }
}

Hope it helps!
