创建参数化restful webservice时没有路由发现错误

i am using symfony 2.2.3 with FOSRestBundle to implement Restful webservices.

here is my code but when i fire following url i am getting following error

No route found for "GET /business/john"

here is the controller code

use FOS\RestBundle\Controller\Annotations as Rest;
use Symfony\Component\HttpKernel\Exception\NotFoundHttpException;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\JsonResponse;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;

use Symfony\Component\Security\Core\Exception\AccessDeniedException;

use FOS\RestBundle\Controller\FOSRestController;
use FOS\RestBundle\Routing\ClassResourceInterface;

class BusinessController extends Controller {


        public function getBusinessAction($para){


          return new JsonResponse(array('name' => $para));
        } 

}

here is my url

http://localhost/symfony/web/app_dev.php/business/john

here is my route

if i remove the argument from url and from function getBusinessAction then it works but not with arguments/

_business:
    resource: "@HubHomeBundle/Controller/BusinessController.php"    
    type: rest

update

inside app/confing/routing.yml

   hub_home:
    resource: "@HubHomeBundle/Resources/config/routing.yml"

Just to make sure, is this from HubHomeBundle/Resources/config/routing.yml?

_business:
    resource: "@HubHomeBundle/Controller/BusinessController.php"    
    type: rest

If so try editing it and changing it to:

_business:
    resource: HubHomeBundle\Controller\BusinessController   
    type: rest

The value of your 'resource' tag should be the fully qualified name of the controller Class, not the path to the file
