Sql DAO和多个数据库不'；我不能在春天和科特林一起工作

我正在和科特林学习春季（靴子）。 我设法用JPA存储库设置了一个工作的Spring应用程序

interface APixRepo : org.springframework.data.repository.Repository<APix, EroPixKulcs>
{
  @Query( value="select * from felhaszn"
        , nativeQuery = true
        )
  fun sokasag(): Iterable<APix>
}

其中APix是我的实体类。以及另外两个类似的实体、回购协议和控制器。
（本地SQL对我来说很重要，这是我最擅长的。）
由于这三个实体位于三个不同的数据库中，我不得不使用所描述的XxxDataSourceConfiguration魔法（Xxx=APix和另外两个）。
它仍然有效

现在我意识到repo方法对我不好，因为我的SQL必须是动态的，并且您只能在@Query（）中编写常量SQL。 因此，我根据以下内容将回购协议更改为DAO：

及

我试过：

class AKontroller(@org.springframework.beans.factory.annotation.Qualifier("apixEntityManager") private val dao: APixRepo)

class APixRepoImpl constructor(@PersistenceContext @org.springframework.beans.factory.annotation.Qualifier("apixEntityManager") var em: EntityManager)

现在是错误：

当我在两个位置都尝试注释时，错误与我仅在Acontroller中尝试相同

在这一点上，我放弃了，来这里寻求帮助
