MappedSuperclass annotation issue

[pimuzzo]

Hi, I am using 1.11.03 and I have the spring configuration in xml in this way:

    <jpa:repositories base-package="my.package.datamodel.repositories"
                      factory-class="com.cosium.spring.data.jpa.entity.graph.repository.support.EntityGraphJpaRepositoryFactoryBean"
                      entity-manager-factory-ref="entityManagerFactory" />

I have some classes annotated with @MappedSuperclass and I have this issue:

java.lang.IllegalArgumentException: Not an entity: class com.liberologico.cloudesire.datamodel.entities.MetadataEntity

Hi @pimuzzo ,

Can you show me the used repository class and repository method call that generates this exception?

[reda-alaoui]

@pimuzzo , did you solve your issue?

[pimuzzo]

Not yet, I'll try to debug it better and write a test, if you want we can close it for now, and I'll open again if necessary

[reda-alaoui]

@pimuzzo , ok, reopen when ready ;)

[pimuzzo]

Well, I fixed it!!! Sorry if I am late. I've this situation: first @Entity public class SubscriptionMetadata extends MetadataEntity second @Entity public class CustomerMetadata extends MetadataEntity a @MappedSuperclass public abstract class MetadataEntity extends BaseEntityId

And the repository was:

public interface MetadataRepository extends JpaRepository<MetadataEntity, Integer>
{
    CustomerMetadata findByCompanyAndUser( Company company, User user );

    SubscriptionMetadata findBySubscription( Subscription subscription );
}

And to make it works I've splitted it in 2 repositories SubscriptionMetadataRepository and CustomerMetadataRepository.

Thanks for your hint to watch the repositories ;)
