java - 在Hibernate中删除子对象的问题“被删除的对象将通过层叠重新保存”

我有以下两个实体：

1-交易

@OneToMany(cascade=CascadeType.ALL,mappedBy = "deal", fetch = FetchType.EAGER)
@Fetch( FetchMode.SELECT)
private List<DealCheckList> dealCheckList;

2-DealCheckList

@JoinColumn(name = "DEAL_ID", referencedColumnName = "DEAL_ID", insertable = false, updatable = false)
@ManyToOne(fetch = FetchType.LAZY)
private Deal deal;

在删除子对象即DealCheckList时使用

.......
.......
transaction = session.beginTransaction();

Deal deal = (Deal) session.createCriteria(Deal.class)
                          .add(Restrictions.eq("dealId",  dealId)).uniqueResult();

for(DealCheckList checklist : deal.getDealCheckList()){
            session.delete(checklist);
 }
transaction.commit();

我收到以下错误

Caused by: org.hibernate.ObjectDeletedException: deleted object would be re-saved by cascade (remove deleted object from associations):

请帮忙。

最佳答案

您需要从DealCheckList中删除清单对象。
您的DealCheckList列表具有“ cascade all”，因此，如果其中包含对象，则将自动保存它。

错误消息很清楚“从关联中删除已删除的对象”
