Symfony Listener 在 Controller 的小改动后消失了

Question

我在使用 Symfony 监听器时遇到了一些奇怪的行为。我有一个工作配置，但是当我更改或向控制器添加某些内容时，Expected to find class "App\EventListener\AuthenticationSuccessListener" 出现。更改可能只是路由路径字符串中的内容。所有代码都是here。删除缓存和服务器重启没有帮助。

namespace AppBundle\EventListener;

use Lexik\Bundle\JWTAuthenticationBundle\Event\AuthenticationSuccessEvent;
use Lexik\Bundle\JWTAuthenticationBundle\Event\AuthenticationFailureEvent;
use Lexik\Bundle\JWTAuthenticationBundle\Response\JWTAuthenticationFailureResponse;
use Symfony\Component\Serializer\SerializerInterface;

class AuthenticationListener
{
    /**
     * @var SerializerInterface
     */
    private $serializer;

    public function __construct(SerializerInterface $serializer)
    {
        $this->serializer = $serializer;
    }

    /**
     * @param AuthenticationSuccessEvent $event
     */
    public function onAuthenticationSuccessResponse(AuthenticationSuccessEvent $event)
    {

        $event->setData([
            'user' => $this->serializer->normalize($event->getUser(), null, ['groups' => ['basic']]),
            'token' => $event->getData()['token'],
        ]);

    }

}

控制器

<?php

namespace App\Controller;

use App\Entity\User;
use Doctrine\ORM\EntityManager;
use Doctrine\ORM\EntityManagerInterface;

class ApiUserController extends AbstractController
{
    /**
     * @Route("/api/verify_token", methods="POST", name="api_verify_token")
     * @IsGranted("ROLE_USER")
     */
    public function verifyToken(User $user = null){
        return new JsonResponse([], 200);
    }

}

由@Jakumi 回答解决。错误是由 namespace AppBundle\EventListener 引起的。改成App\EventListener后错误消失。
