How can I get container object in repository class without passing parameter?

You will get container object as follow:

// include files to get container
use Symfony\Component\DependencyInjection\ContainerInterface;
use Symfony\Component\DependencyInjection\ContainerAwareInterface;

class ClassNameRepository extends EntityRepository implements ContainerAwareInterface
{
    /**
     * @var ContainerInterface
     *
     * @author Ashok Chitroda <[email protected]>
     */
    private $container;

    public function setContainer(ContainerInterface $container = null)
    {
        $this->container = $container;
    }
}

Thanks
