Php 使用ResolveTargetEntityListener时，关联字段的类型实体的预期值改为Entity1

我正在使用条令中的ResolveTargetEntityListener访问外部数据库中的SQL表

当我使用createQueryBuilder查询外部/基本车辆类的数据时，我得到以下错误：

关联字段AppBundle\Entity\FM\u Positions$truck的类型AppBundle\Entity\VehicleFox的预期值为$truck，取而代之的是FoxBundle\Entity\Vehicle

在内部VehicleFox类上执行此操作时，查询返回NULL

有什么我错过的吗

下面是我正在使用相关功能进行查询的控制器。我还包括了已经使用过的类和接口以及config.yml文件

如果我明白的话，您正在尝试创建新的FM_位置实体，但当您尝试选择一个车辆并将其与位置关联时，您可能会遇到异常或空结果是正确的@OlivierCDid，您尝试精确使用entityManager，因为您没有默认的$repository=$this->getDoctrine->getRepository'AppBundle:VehicleFox'，maxem'；我已经设置了默认的实体管理器：maxem，还尝试了$repository=$this->getdoctor->getRepository'AppBundle:VehicleFox'，maxem'；我仍然得到一个空结果我猜结果数组来自一个表单，你能提供表单的代码和你构建它的动作吗
