and implement it

public class AggregateRepositoryImpl extends JPARepository<Aggregate, UUID> implements AggregateRepository {

    @Inject
    public AggregateRepositoryImpl(@Nonnull JPAApi jpaApi, @Nonnull DatabaseExecutionContext executionContext) {
        super(jpaApi, executionContext, Aggregate.class);
    }

    @Override
    public UUID nextIdentity() {
        return UUID.randomUUID();
    }
}
