当isUpdated为true且不更新删除的行时，Java spring jpa保存所有行

@Repository
public interface YourEntityRepository extends JpaRepository<YourEntity, Long> {
}

@Service
public class YourService {
    private final YourEntityRepository yourEntityRepository;

    public YourService(YourEntityRepository yourEntityRepository) {
        this.yourEntityRepository = yourEntityRepository;
    }

    public void saveAllRows(boolean isUpdated) {
        if (isUpdated) {
            List<YourEntity> allRows = yourEntityRepository.findAll();
            yourEntityRepository.saveAll(allRows);
        }
    }
}
