发出此错误。然后我找到了非常相似的答案，并遵循它，chage Entity class to：

@Entity
//@Table( name = "excursion_time_table" )
public class ExcursionTimeTable
{

但这无济于事。如何使用Gradle + Spring + Hibernate项目实现LightAdmin？

编辑：

@Transactional
public interface IExcursionRepository extends PagingAndSortingRepository<Excursion, Integer>
{
}

关注this example我在上面创建了界面。然后我创建了默认类，它实现了这个接口（默认值由IDE生成）。然后我在配置中实现了一些bean。

@Bean public ExcursionRepository excursionDynamicJpaRepository（） {     返回新的ExcursionRepository（）; }

仍然没有。 LightAdmin没有为我开始。

答案 0 :(得分：2)

刚刚在沙箱中使用了您的模型，似乎问题在于为具有原始主键的实体创建动态JPA存储库。

我已经创建了ticket on GitHub以获得正确的解决方案，但是来解决您的问题，只需使用数字包装器类型（Long等）。

答案 1 :(得分：1)

您无需创建IExecursionRepository的实施。 Spring Data JPA将为您做到这一点。请尝试删除您的ExcurationRepository课程及其@Bean方法。 Spring Data JPA将自动创建一个类型为IExcursionRepository的bean，可以将其注入到应用程序的类中。

您可以在问题中链接到的示例中看到这一点。该应用程序具有HotelRepository接口，但不会自行实现。使用由Spring Data JPA自动创建的此接口的实现。例如，您可以看到它被注入ApplicationController。
