如果进行修改，则会给出org.hibernate.NonUniqueObjectException。
在我的 BidderBO 类(class)中
@Override
@Transactional(propagation=Propagation.REQUIRED, rollbackFor=Exception.class)
public boolean updateBidder(BiddersDetailForm bidderDetailForm, MISSessionBean misSessionBean) throws MISException {
boolean status = false;
boolean childStatus =false;
try {
BidderHeaderBean bidderHeaderBean = populaBidderHeaderBean(bidderDetailForm);
MISAuditBean misAuditBean = new MISAuditBean();
misAuditBean.setStatus(MISConstants.MASTER_STATUS_VERIFIED);
misAuditBean.setEntBy(misSessionBean.getEnteredBy());
misAuditBean.setEntDate(misSessionBean.getEnteredDate());
bidderHeaderBean.setMisAuditBean(misAuditBean);
status = bidderHeaderDao.updateBidderHeader(bidderHeaderBean);
if(status){
long bidderInfoId = bidderDetailForm.getBidInfoId();
List<BidderDetailBean> bidderDetailBeans = populateBidderDetailBeans(bidderDetailForm, bidderInfoId, misSessionBean, MISConstants.MASTER_STATUS_VERIFIED);
log.debug("\nBidder DetailBeans\t"+bidderDetailBeans);
for(BidderDetailBean bidderDetailBean:bidderDetailBeans ){
log.debug("bank name ==========="+bidderDetailBean.getBankName());
log.debug("bid amount ==========="+bidderDetailBean.getBidAmount());
log.debug("getBidderName ==========="+bidderDetailBean.getBidderName());
log.debug("getBidInfoId ==========="+bidderDetailBean.getBidInfoId());
log.debug("getSeqBidId ==========="+bidderDetailBean.getSeqBidId());
log.debug("status ==========="+bidderDetailBean.getMisAuditBean().getStatus());
log.debug("bid sale date ==========="+bidderDetailBean.getMisAuditBean().getEntDate());
}
childStatus = bidderDetailDao.updateBidderDetailBeans(bidderDetailBeans);
if(!childStatus){
throw new MISException(MISExceptionCodes.MIS003, "Bidder Details are not updated for "+bidderDetailForm.getTenderId());
}
}
} catch (DataAccessException e) {
log.error(e.getLocalizedMessage(),e);
throw new MISException(e.getMostSpecificCause());
} catch (MISException e) {
log.error(e.getLocalizedMessage(),e);
throw e;
}
return status && childStatus;
}
而Bean(BidderDetailBean)是
public class BidderDetailBean implements Serializable {
/**

private static final long serialVersionUID = -2234569083113434751L;
@Id

public Date getBidSaleDate() {

}
public void setBidSaleDate(Date bidSaleDate) {
this.bidSaleDate = bidSaleDate;
}
................................
而 BidderHeaderBean 是......
public class BidderHeaderBean implements Serializable {
/**

private static final long serialVersionUID = 6163541390640145180L;
@Id

private Set<BidderDetailBean> bidderDetailBeans;
public long getBidInfoId() {
return bidInfoId;
}
public void setBidInfoId(long bidInfoId) {
this.bidInfoId = bidInfoId;
}
我的 daoimpl 类正在使用这个函数......
@Override
public boolean saveOrUpdateBidderDetailBeans(Collection<BidderDetailBean> bidderDetailBeans) throws DataAccessException {
try {
System.out.println("bidderDetailBeans----in dao===="+bidderDetailBeans.toString());
getHibernateTemplate().flush();
getHibernateTemplate().saveOrUpdateAll(bidderDetailBeans);
getHibernateTemplate().flush();
getHibernateTemplate().clear();
} catch (DataAccessException e) {
throw e;
}
return true;
}
请提供一些指导，我也尝试过清除功能、合并和 saveOrUpdate 但它不起作用。 它给出错误............

最佳答案
每当您为先前附加到当前 session 的实体调用 saveOrUpdate(这意味着 session 实体附加)时，都会引发此异常。
一种解决方法是使用合并，仅当尚未附加任何实体时才附加实体，在这种情况下，它只是将已附加的实体合并到作为参数给出的当前实体。
BidderHeaderBean 有一个不可插入/可更新的子关联:
@OneToMany(targetEntity=BidderDetailBean.class, fetch=FetchType.EAGER)
@JoinColumn(name="bid_info_id", insertable=false, updatable=false)
private Set<BidderDetailBean> bidderDetailBeans;
这不是一个mappedBy 或inverse 的。 BidderDetailBean 也没有与 BidderHeaderBean 的关联，因此该关联永远无法工作，因为外键永远不会被插入/更新。
关于java - 在 Hibernate3 中的 saveOrUpdateAll 情况下，具有相同标识符值的不同对象已与 session 关联，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/24444385/
