我使用Doctrine中的ResolveTargetEntityListener来访问外部数据库中的SQL表。
当我使用createQueryBuilder查询外部/基础Vehicle类的数据时，我收到以下错误：
Expected value of type "AppBundle\Entity\VehicleFox" for association field "AppBundle\Entity\FM_Positions#$truck", got "FoxBundle\Entity\Vehicle" instead.
当我在内部VehicleFox类上执行此操作时，Query将返回NULL。
有什么我错过的吗？
以下是我正在使用相关功能进行查询的Controller。我还包括已经使用的类和接口以及config.yml文件。
