保存具有复杂关系的实体时出现 StaleStateException

2022-01-24 00:00:00 persistence save spring java Hibernate

我保存在数据库 (Oracle) 中的休眠实体具有非常复杂的关系,因为它具有许多相关实体.它看起来像这样......

The hibernate entity I am saving in the database (Oracle) has very complex relations, in the sense that it has many related entities. It looks something like this...

@Table(name = "t_HOP_CommonContract")
public class Contract {
    @Id
    private ContractPK id;

    @OneToOne(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
    @PrimaryKeyJoinColumn
    private ContractGroupMember contractGroupMember;

    @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
    @JoinColumns({
        @JoinColumn(name = "TransactionId", referencedColumnName = "TransactionId"),
        @JoinColumn(name = "PrimaryContractId", referencedColumnName = "PrimaryContractId")
    })
    @Fetch(FetchMode.SUBSELECT)
    private List<ContractLink> contractLinks;

    // . . . . . . . 

    // A couple of more one to many relationships

    // Entity getters etc.

}

我还有几个实体,例如...

I also have a couple of more entities such as...

@Table(name = "t_HOP_TRS")
public class TotalReturnSwap {
    @Id
    private ContractPK id;
    // Entity Getters etc.
}

诀窍是我必须在同一事务中对 ContractTotalReturnSwap 实体进行持久化.

The trick is that I have to do persistence of Contract and TotalReturnSwap entities in the same transaction.

有时它可能是必须在同一个事务中持久化的一堆实体.

Sometimes it could be a bunch of entities that have to be persisted in the same transaction.

我在保存 TotalReturnSwap 实体时注意到以下异常(这总是在我保存 Contract 实体后完成).

I have noticed the following exception when I save the TotalReturnSwap entity (which is always done after I have saved the Contract entity).

现在有几点可能有助于回答问题:

Now a few points that may help while answering questions:

  • 我只是在数据库中保存(插入)实体 - 从不更新/删除/读取
  • 即使在单线程环境中,我也能够隔离此异常,因此即使我们的应用程序是多线程的,它看起来也不像是多线程问题

推荐答案

这个错误可能是由几个原因引起的:

The error can be caused by several things:

  1. 在提交对象之前刷新数据可能会导致清除所有等待持久化的对象.
  2. 如果对象具有自动生成的主键并且您正在强制分配一个键
  3. 如果您在将对象提交到数据库之前清理对象.
  4. 零或不正确的 ID:如果您将 ID 设置为零或其他值,Hibernate 将尝试更新而不是插入.
  5. Object is Stale:Hibernate 缓存会话中的对象.如果对象被修改了,而 Hibernate 不知道它,它会抛出这个异常——注意 StaleStateException

我没有把它归功于它,发现它 这里.

I'm not taking the credit for it, found it here.
