hibernate - 大对象不能用于自动提交模式

Question

我正在开发一个使用 spring 和 hibernate 的应用程序。我们使用 postgresql 作为数据库。

当我尝试将记录插入到具有 OID 列的表中时，它会抛出以下错误。

异常表明在自动提交模式下可能无法使用大对象，但是当我看到来自 spring 和 hibernate 的以下日志时，它表示自动提交模式已禁用。

这是spring事务和hibernate jdbc连接管理器的日志

在此日志中，前几行表示方法 MailManager.sendMail() 正在运行事务 block 并且默认自动提交状态为 true，但下一行表示自动提交已禁用。

谁能告诉我为什么 postgresql 在实际禁用自动提交模式时抛出“大对象不能用于自动提交模式”异常。

谢谢。

Answer 1

问题是我的应用程序中有两个不同的 SessionFactories。其中只有1家有关联交易。我使用没有事务的 sessionFactory 保存带有大对象的对象。

因为我使用的是 dbcp 池，所以连接的 autoCommit 属性设置为 true。

我通过更改两个不同的 sessionFactories 的使用来修复它，现在我只使用一个在 HibernateTransaction 中工作的 sessionFactory。这解决了问题，因为事务管理器将 autoCommit 属性设置为 false。
