Java 使用hibernate从父实体在子实体中插入数据时未找到ParentKey异常

java hibernate

Java 使用hibernate从父实体在子实体中插入数据时未找到ParentKey异常,java,hibernate,spring-orm,Java,Hibernate,Spring Orm,我的需要是保存父表，父实体将在子表中级联数据（插入/更新）。早些时候，我们可以节省。我们对主键/外键进行了一些修改，之后在保存数据时出现以下异常 谢谢你，请帮忙。在过去的两天里，我们一直在努力解决此错误 异常和堆栈跟踪：： 14:13:34,735 INFO [org.hibernate.engine.jdbc.batch.internal.AbstractBatchImpl] (http-localhost-127.0.0.1-8080-1) HHH000010: On release of

在RC_CUST_RESP_USER表中，我有主键rcCustId，而RcUserXGroup和RcUserXCompany有外键指向RC_CUST_RESP_USER.rcCustId

服务类：：服务类调用helper来生成模型，模型被传递到dao层

@Service("userManagementService")
@Transactional
public class UserManagementServiceImpl implements UserManagementService {

    private static Logger logger = LogManager.getLogger(UserManagementServiceImpl.class);

    @Autowired
    private RcCustRespUserDao rcCustRespUserDao;

    @Autowired
    private UserManagementServiceHelper userManagementServiceHelper;

    @Override
    public boolean createUser(User userDto) throws RCException {
        RcCustRespUser rcCustRespUser = userManagementServiceHelper.getUserModelFromDto(userDto);
        rcCustRespUserDao.saveOrUpdate(rcCustRespUser);

试一试{
getSession（）.saveOrUpdate（实例）；
log.debug（“连接成功”）；

在我看来，不应该对这些陈述进行评论。这将建立对象之间的关系。你能试着取消注释吗？***//rcUserXGroup.setRcCustRespUser（rcCustRespUser）；和***//rcUserXCompany.setrcustrespuser（rccustrepuser）；谢谢，这段代码被意外地注释了，不管怎样，问题出在数据库映射的末尾。现在已经解决了，工作正常。在我看来，这些声明不应该被评论。这将建立对象之间的关系。你能试着取消注释吗？***//rcUserXGroup.setRcCustRespUser（rcCustRespUser）；和***//rcUserXCompany.setrcustrespuser（rccustrepuser）；谢谢，这段代码被意外地注释了，不管怎样，问题出在数据库映射的末尾。现在已经解决了，工作正常。
