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

Question

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 {


/**
 * Initial Version
 */
private static final long serialVersionUID = -2234569083113434751L;


@Id
@GeneratedValue(generator = "seq_bid_id", strategy = GenerationType.AUTO)
@SequenceGenerator(name = "seq_bid_id", sequenceName = "prwss_main.seq_bid_id")
@Column(name = "seq_bid_id", nullable = false)
private long seqBidId;


@Column(name="bid_info_id", nullable=false)
private long bidInfoId;


@Column(name="bidder_name", nullable=false)
private String bidderName;

@Column(name="bid_sale_date")
private Date bidSaleDate;

@Column(name="bid_submitted")
private String bidSubmitted;

@Column(name="emd_amount")
private double emdAmount;

@Column(name="emd_valid_upto")
private Date emdValidUpto;

@Column(name="emd_instrument_type")
private String emdInstrumentType;

@Column(name="bank_name")
private String bankName;

@Column(name="not_responsive")
private String notResponsive;

@Column(name="bidder_contact_number")
private String contactNumber;

@Column(name="remarks")
private String remarks;

@Column(name="bid_amount")
private double bidAmount;

@Embedded
private MISAuditBean misAuditBean;

public long getBidInfoId() {
    return bidInfoId;
}

public void setBidInfoId(long bidInfoId) {
    this.bidInfoId = bidInfoId;
}

public String getBidderName() {
    return bidderName;
}

public void setBidderName(String bidderName) {
    this.bidderName = bidderName;
}

public Date getBidSaleDate() {
    return bidSaleDate;
}

public void setBidSaleDate(Date bidSaleDate) {
    this.bidSaleDate = bidSaleDate;
}

................................

而 BidderHeaderBean 是......

public class BidderHeaderBean implements Serializable {

/**
 * Initial Version
 */
private static final long serialVersionUID = 6163541390640145180L;

@Id
@SequenceGenerator(name="seq_bid_info_id",      sequenceName="prwss_main.seq_bid_info_id")
@GeneratedValue(generator="seq_bid_info_id", strategy=GenerationType.AUTO)
@Column(name="bid_info_id", nullable=false)
private long bidInfoId;

@Column(name="location_id")
private String locationId;

@Column(name="tender_id")
private String tenderId;

@Column(name="bidding_phase")
private int biddingPhase;

@Column(name="bid_opening_date")
private Date bidOpeningDate;

@Column(name="reference_tender_id")
private String referenceTenderId;

@Embedded
private MISAuditBean misAuditBean;

@OneToMany(targetEntity=BidderDetailBean.class, fetch=FetchType.EAGER)
@JoinColumn(name="bid_info_id", insertable=false, updatable=false)
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............

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。
