如何在symfony中恢复先前的page路由名称

# config/routes.yaml
my_route:
    path: /my-path
    controller: App\Controller\MyController::myAction
    _name: my_previous_route_name

// src/Controller/MyController.php
namespace App\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;

class MyController extends AbstractController
{
    /**
     * @Route("/my-action", name="my_action")
     */
    public function myAction(): Response
    {
        // 重定向到先前页面的路由名称
        return $this->redirectToRoute('my_previous_route_name');
    }
}

{# templates/my_template.html.twig #}

<a href="{{ path('my_previous_route_name') }}">Go back</a>
