 You also have the possibility to prefix allroute names defined in a controller
 class with the ``name`` attribute of the ``@Route`` annotation::
 You also have the possibility to prefixthe names ofallthe routes defined in
 a controller class or imported from a configuration file:

    use Symfony\Component\Routing\Annotation\Route;
 .. configuration-block::

    /**
     * @Route(name="blog_")
     */
    class BlogController extends Controller
    {
        /**
         * @Route("/blog", name="index")
         */
        public function indexAction()
        {
            // ...
        }
    .. code-block:: php-annotations

        use Symfony\Component\Routing\Annotation\Route;

        /**
         * @Route("/blog/posts/{slug}",name="post")
         * @Route(name="blog_")
         */
 public function showAction(Post $post)
 class BlogController extends Controller

            public function indexAction()
            {
                // ...
            }

            /**
             * @Route("/blog/posts/{slug}", name="post")
             */
            public function showAction(Post $post)

        $app->addNamePrefix('blog_');

        $collection = new RouteCollection();
        $collection->addCollection($app);

        return $collection;

 In this example, the names of the routes will be ``blog_index`` and ``blog_post``.

 .. versionadded:: 4.1
    The option to prefix route names in YAML, XML and PHP files was introduced
    in Symfony 4.1. Previously only the ``@Route()`` annotation supported this
    feature.
