我在 Java J2EE Web 应用程序中使用 Hibernate 3.5.2 和 Spring Core 3.0.1。当不同的用户同时更新同一记录时，我收到 StaleObjectStateExcpetion 。事务由 javax.persistence.EntityManager 管理。以下是我创建问题所采取的步骤。
- 用户 1 登录应用程序
- 用户2登录应用程序
- 用户1开始编辑记录A
- 用户2开始编辑记录A
- 用户1保存记录A
- 用户2保存记录A
- 抛出 org.hibernate.StaleObjectStateException(见下文)
我读到这是由数据库中更新的版本号与该特定实体当前内存中的版本号之间的差异引起的。但是，当我尝试使用查询或使用 EntityManager.find() 方法在数据库中查找当前版本号以从数据库获取最新信息时，我发现版本号没有任何差异。我还尝试手动合并旧实体和新实体之间的更改并使用entityManager.merge(object) 方法，但没有成功。关于如何解决此问题有什么想法吗？

最佳答案
以下是乐观锁定的工作原理:
- 用户 1 开始编辑 recordA -
recordA已从数据库加载，版本为V - 用户2开始编辑recordA -
recordA从版本V的数据库加载 - 与上面完全相同 User1 保存 recordA -
recordA已保存，但 Hibernate 透明地添加:UPDATE ... SET V = V + 1 WHERE version = V此时Hibernate会验证从数据库返回的修改记录数是否正好为1。如果查询修改了 0 条记录，则意味着不满足
WHERE version = V子句。在本例中，一切顺利，版本设置为V + 1(重要!)User2 保存 recordA - Hibernate 执行完全相同的操作，内存中仍然保留旧的
V版本号。不幸的是，在这种情况下，不满足WHERE version = V条件，因为版本现在是V + 1。该查询返回 0 个修改记录，这使得 Hibernate 相信(正确地)该记录同时被修改。这就是异常所说的内容。
那么你能做些什么呢？只需捕获异常即可:
重复整个事务，但重新加载实体(使用新版本
V + 1)，以便更新后不会丢失最后的更改或者通知用户对象在此期间已被修改，以便她可以检查新版本。
这两种解决方案都可以，具体取决于您的用例。
关于并发更新期间的 Hibernate StaleObjectStateException，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/8975766/
