Symfony2的：未找到路線「GET /屬/章魚/」

Question

做我的第一個應用程序從http://knpuniversity.com/screencast/symfony/ 這是非標準的錯誤，但我不知道如何調試它，事業debug:error路線/genus/{genusName}是存在

（genus/{genusName}/notes工作良好）

的routing.yml

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

的src /的appbundle /控制器/ GenusController.php

<?php 
namespace AppBundle\Controller; 
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method; 
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route; 
use Symfony\Bundle\FrameworkBundle\Controller\Controller; 
use Symfony\Component\HttpFoundation\JsonResponse; 
use Symfony\Component\HttpFoundation\Response; 
class GenusController extends Controller 
{ 
    /** 
    * @Route("/genus/{genusName}") 
    */ 
    public function showAction($genusName) 
    { 
     return $this->render('genus/show.html.twig', array(
      'name' => $genusName, 
     )); 
    } 
    /** 
    * @Route("/genus/{genusName}/notes", name="genus_show_notes") 
    * @Method("GET") 
    */ 
    public function getNotesAction($genusName) 
    { 
     $notes = [ 
      ['id' => 1, 'username' => 'AquaPelham', 'avatarUri' => '/images/leanna.jpeg', 'note' => 'Octopus asked me a riddle, outsmarted me', 'date' => 'Dec. 10, 2015'], 
      ['id' => 2, 'username' => 'AquaWeaver', 'avatarUri' => '/images/ryan.jpeg', 'note' => 'I counted 8 legs... as they wrapped around me', 'date' => 'Dec. 1, 2015'], 
      ['id' => 3, 'username' => 'AquaPelham', 'avatarUri' => '/images/leanna.jpeg', 'note' => 'Inked!', 'date' => 'Aug. 20, 2015'], 
     ]; 
     $data = [ 
      'notes' => $notes 
     ]; 
     return new JsonResponse($data); 
    } 
} 

應用程序/資源/視圖/屬/ show.html.twig

{% extends 'base.html.twig' %} 
{% block title %}Genus {{ name }}{% endblock %} 
{% block body %} 
    <h2 class="genus-name">{{ name }}</h2>

路線中的路徑配置不包含尾部斜線。爲了使您的示例能夠正常工作，您需要在嘗試訪問控制器時（例如，/genus/octopus而不是/genus/octopus/）刪除尾部斜線，或者將斜槓添加到路由配置中。
