Symfony：NotFoundHttpException：找不到"GET /lucky/number"的路由

我是symfony的新手，我正在尝试向演示应用程序添加一个新页面，我在关注这个芭蕾舞团

我添加了这个控制器src/AppBundle/controller/LuckyController.php

// src/AppBundle/Controller/LuckyController.php
namespace AppBundleController;
use SymfonyBundleFrameworkBundleControllerController;
use SensioBundleFrameworkExtraBundleConfigurationRoute;
use SymfonyComponentHttpFoundationResponse;
class LuckyController extends Controller
{
/**
 * @Route("/lucky/number")
 */
 public function numberAction()
 {
    $number = rand(0, 100);
    return new Response(
        '<html><body>Lucky number: '.$number.'</body></html>'
    );
  }
}

应用程序/控制台路由器：调试返回：

当我导航到http://127.0.0.1:8000/app_dev.php/lucky/number，我收到这个错误

NotFoundHttpException: No route found for "GET /lucky/number"

我的路线。yml

app:
resource: @AppBundle/Controller/
type:     annotation
prefix:   /{_locale}
requirements:
    _locale: %app_locales%
defaults:
    _locale: %locale%
# These lines define a route using YAML configuration. The controller used by
# the route (FrameworkBundle:Template:template) is a convenient shortcut when
# the template can be rendered without executing any logic in your own   controller.
# See   http://symfony.com/doc/current/cookbook/templating/render_without_controller.html
homepage:
path: /{_locale}
requirements:
    _locale: %app_locales%
defaults:
    _controller: FrameworkBundle:Template:template
    template:    'default/homepage.html.twig'
    _locale:     "%locale%"

谢谢。

如果您不想管理路由前缀中带有locale的部分，则应将其删除：

prefix:   /{_locale}
requirements:
    _locale: %app_locales%
defaults:
    _locale: %locale%

您的路由文件必须如下所示：

app:
    resource: @AppBundle/Controller/
    type:     annotation
homepage:
    path: /
    defaults:
        _controller: FrameworkBundle:Template:template
        template:    'default/homepage.html.twig'
