您不应该扩展

@TarasV:谢谢，但您提供的链接是针对用于扩展您当前实体的存储库，但我的存储库与任何实体都没有关系。条令存储库需要指向实体的链接。事情就是这样。您创建了一个不扩展EntityRepository的类，只注入实体管理器或数据库连接对象。@Cerad:实际上，此存储库没有可链接到的实体。我想要的是有一个自定义类，我可以在其中保存原始的基于sql的查询，这些查询从数据库中获取不同类型的内容？也可以在控制器中轻松访问该类？这似乎没有多大意义。Doctrine ORM包中的基本EntityRepository
要求您向其传递一个ClassMetadata
实例。但是，如果您的存储库没有链接到任何实体，您会从哪个实体传递这些信息？看看你的repository类做了什么，我不会扩展EntityRepository
类，只会注入一个执行SQL查询所需的连接
实例。谢谢你的回答，但我注入了DBAL连接并完成了这项工作。
