java – 保存具有复杂关系的实体时的StaleStateException

Question

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

@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


我还有几个实体,比如……

@Table(name = "t_HOP_TRS")
public class TotalReturnSwap {
    @Id
    private ContractPK id;
    // Entity Getters etc.
}
诀窍是我必须在同一个事务中持久化Contract和TotalReturnSwap实体.
有时它可能是一堆必须在同一事务中持久化的实体.
我在保存TotalReturnSwap实体时注意到以下异常(在保存Contract实体后总是这样做).

org.springframework.orm.hibernate3.HibernateOptimisticLockingFailureException: Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1; nested exception is

现在有几点可以帮助回答问题：
>我只在数据库中保存(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
