如何获取缓存驱动程序？（带条令/Redis缓存的Symfony2）

为了在我的Symfony2应用程序中使用Redis Cache，我遵循了以下步骤（法语，对不起！）

一切都很好，除了我使用实体监听器的部分，它来自原则事件，用于在数据库写入时更新缓存。。。我有这样的服务：

<?php

namespace Maxpou\BeerBundle\Service;

use Doctrine\ORM\Event\LifecycleEventArgs;
use Maxpou\BeerBundle\Entity\Beer;

class BeerListener
{
    private $cacheDriver;

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

    public function postPersist(Beer $beer, LifecycleEventArgs $args)
    {
        $this->cacheDriver->expire('[beers_all][1]', 0);
    }

    public function postUpdate(Beer $beer, LifecycleEventArgs $args)
    {
        $this->cacheDriver->expire('[beers_all][1]', 0);
    }

    public function postRemove(Beer $beer, LifecycleEventArgs $args)
    {
        $this->cacheDriver->expire('[beers_all][1]', 0);
    }
}

在我的实体中，我添加了以下注释：

* @ORM\EntityListeners({"Maxpou\BeerBundle\Service\BeerListener"})

当我尝试执行更新时，出现以下错误：

Fatal error: Uncaught ArgumentCountError: Too few arguments to function Maxpou\BeerBundle\Service\BeerListener::__construct(), 0 passed in /var/www/admin2/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/DefaultEntityListenerResolver.php on line 73 and exactly 1 expected in /var/www/admin2/src/Maxpou/BeerBundle/Service/BeerListener.php:12

看来，我的BeerListener中没有$cacheDriver参数

有人会知道为什么

PS:我使用“symfony/symfony”：“~2.5.0”，“条令/orm”：“~2.2”，“条令/条令包”：“~1.2”，“条令/条令缓存包”：“~1.0”，“snc/redis包”：“1.1.x”，“predis/predis”：“^1.0”（在NGINX/PHP-7.1 env中）
