扩展Spring数据CoroutineCrudRepository引发PropertyReferenceException

如何解决扩展Spring数据CoroutineCrudRepository引发PropertyReferenceException

在我的项目中，我有一个Kotlin（1.3.72）Spring Boot（2.3.3.RELEASE）JPA支持的存储库，该存储库运行良好，Spring应用程序上下文正常启动，项目通过了所有测试，等等。等等：

@Repository
interface MappingRepository : CrudRepository<RoutingMapping,Long> {
    fun findByCompanyId(companyId: Long): RoutingMapping?
}

当我像这样将其切换为扩展org.springframework.data.repository.kotlin.CoroutineCrudRepository而不更改其他任何内容时：

@Repository
interface MappingRepository : CoroutineCrudRepository<RoutingMapping,Long> {
    fun findByCompanyId(companyId: Long): RoutingMapping?
}

启动Spring应用程序上下文在启动时失败，并引发以下内容：

Caused by: org.springframework.data.mapping.PropertyReferenceException:
No property count found for type RoutingMapping!`

这是一个令人困惑的异常，因为RoutingMapping是映射的@Entity。我不清楚我是否@Entity方面缺少什么，或者是我对如何使用org.springframework.data.repository.kotlin.CoroutineCrudRepository的误解。
