Php Symfony从代理对象抓取数据

我有下面的代码来获取一个数组，其中包含一个App\Entity\Player。我想知道俱乐部的名称和财产。这给了我一个错误：App\Entity\Player:：getClub（）：返回值的类型必须是Club，proxy\u CG\uu\App\Entity\Club returned。例如，我如何获取俱乐部名称

        $player_data = array();

        $em = $this->getDoctrine()->getManager();
        $query = $em->createQuery("SELECT p FROM App\Entity\Player p  WHERE p.user = :id");
        $query->setParameter('id', $user_id);
        $player = $query->getResult();
        array_push($player_data, $player[0]->getClub()->getName());

当我转储$player对象时，会得到以下结果： 请注意代理\u CG\uu\App\Entity\Club

原则代理自动扩展您的实体（
App\entity\Club
）。但是在
Player
实体上的方法
getClub（）
的返回类型中，您有
\Club
（完全没有名称空间）。它与
App\Entity\Club
（名称空间
App\Entity
）不同。您需要更改此类型（以及文件中的其他类型）以使用正确的命名空间

要在返回类型中获取命名空间
App\Entity\Club
，您需要使用
\App\Entity\Club
（带前导斜杠）或
Club
（不带前导斜杠）
我认为问题在于您的返回类型
\Club
与
App\Entity\Club
完全不同。前面的“\”将使PHP在全局名称空间中查找该类，这可能就是类型不匹配的原因。换句话说，
Club
引用当前名称空间中的类，即
App\Entity\Club
，而
\Club
引用全局名称空间中的类。名称空间在文件顶部定义，请参见播放器实体文件中的
名称空间：App\Entity
。当我按照您的建议将其更改为
App\Entity\Club
的返回类型时。我收到以下错误：
App\Entity\Player:：getClub（）：返回值的类型必须为App\Entity\App\Entity\Club，返回的代理\\uuuuu CG\uuuuu\App\Entity\Club。
请尝试将其与前导斜杠一起使用。不带前导斜杠，将当前命名空间用作根。您需要返回
\App\Entity\Club
或只返回
Club
（不带前导斜杠）@user10031659我更新了我的答案以便更清楚谢谢！！这对我有用。由于我是Symfony的新手，我一整天都在思考这个问题。编辑：仅供参考，我使用PHPstorm生成了getter和setter，所以出现了问题。
