Spring JPA连表查询重复关联如何解决？

specification<userentity> specification = (root, query, criteriabuilder) -> {
    predicate predicate = criteriabuilder.conjunction();
    join<userentity, userarchiveentity> userarchiveentityjoin = root.join("userarchive", jointype.left);
    return predicate;
};

@Repository
public class UserRepositoryImpl implements UserRepositoryCustom {

    @Autowired
    private UserRepository userRepository;

    @Override
    public Page<UserEntity> findAllWithUserArchive(Specification<UserEntity> specification, Pageable pageable) {
        EntityGraph<UserEntity> entityGraph = EntityGraph.of(UserEntity.class)
                .addSubgraph("userArchive");
        return userRepository.findAll(specification, pageable, entityGraph);
    }

    @Override
    public Page<UserEntity> findAllWithUserArchiveAndNation(Specification<UserEntity> specification, Pageable pageable) {
        EntityGraph<UserEntity> entityGraph = EntityGraph.of(UserEntity.class)
                .addSubgraph("userArchive")
                .addSubgraph("userArchive.nation");
        return userRepository.findAll(specification, pageable, entityGraph);
    }
}
