Symfony 中的路由“不存在”，即使它在主路由文件中声明

Question

以下是相关文件的内容：

内容app/config/routing.yml：

horse_route:
    path:   /horse
    defaults: { _controller: AppBundle:Horse:show }


app:
    resource: "@AppBundle/Controller/"
    type:     annotation

内容src/AppBundle/Controller/WalrusController.php：

<?php

namespace AppBundle\Controller;

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;


class WalrusController extends Controller
{

    /**
     * @Route("/walrus/red")
     */
    public function walrusRedirect()
    {

      return $this->redirectToRoute('/horse', array(), 301);

    }   
}

内容src/AppBundle/Controller/HorseController.php：

<?php

namespace AppBundle\Controller;

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;


class HorseController extends Controller
{

    public function showAction()
    {
      return new Response('This is a horse.');
    }

}

当我localhost:8000/walrus/red在浏览器中输入时，我收到错误消息

Unable to generate a URL for the named route "/horse" as such route does not exist.  

似乎我没有在主路由文件中正确声明路由，或者我在错误的地方声明了它。任何帮助表示赞赏。

您的路线已被调用，horse_route因此您需要使用

return $this->redirectToRoute('horse_route', array(), 301);
