This error was given. Then I found quite similar answer and following it, chage Entity class to:

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

But this won't help. What shall I do to implement LightAdmin with Gradle + Spring + Hibernate project?

Edit:

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

Following this example I've created interface above. Then I've created default class, that implements this interface (with default values genereated by IDE). And then I've implemented some beans in the configuration.

@Bean public ExcursionRepository excursionDynamicJpaRepository () { return new ExcursionRepository(); }

Still nothing. LightAdmin didn't started for me.

Solution

Just played a bit with your model in a sandbox and seems like the problem is in creation of dynamic JPA repositories for entities having primitive primary key.

I've created a ticket on GitHub for proper resolution, but to fix your problem, just use a numeric wrapper type (Long, etc.).
