篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了hibernate事务提交相关的知识，希望对你有一定的参考价值。
hibernate事务提交后,是直接持久化到数据库还是只是在缓存里面,我是感觉是数据库，有知道原理的解释下，求详细说明
hibernate 是手动提交事务，比如在操作Session之前有一个 （sess 是Session的一个实例）sess.beginTransaction(); 操作完之后又一个sess.getTransaction().commit(); 提交前会自动调用一个flush（）函数，会把缓存中的数据全部输出去，因此数据库中的数据是事务开始到提交间改动的数据！缓存中没有数据！因此是直接持久化到数据库！ 参考技术A hibernate默认是自动提交 可以自己手动设置：setAutoCommit(false)最后再tx.commit() 参考技术B transaction一旦commit后，内存里的数据就被持久化到数据库里了，内存里的数据没有显示销毁还会在的，直到垃圾回收器判断这个变量不再使用时会销毁掉无法提交 Hibernate 事务；嵌套异常是 org.hibernate.Transaction 异常：JDBC 提交失败
【中文标题】无法提交 Hibernate 事务；嵌套异常是 org.hibernate.Transaction 异常：JDBC 提交失败【英文标题】：Could not commit Hibernate transaction; nested exception is org.hibernate.Transaction Exception: JDBC commit failed 【发布时间】：2013-01-09 07:47:27 【问题描述】：当我连接到应用程序时，我在我的应用程序中使用 Windows Azure SQL Server，它显示以下错误。

【问题讨论】：
跟踪表明连接已关闭。使用检查连接的连接池。 如果我在应用程序中使用了 c3po 连接池。它不起作用 跟踪显示原因：com.microsoft.sqlserver.jdbc.SQLServerException：连接在尝试检查已关闭连接时关闭。您确定 SQLServer 正在接受连接并且从 C3P0 返回的连接确实是活动连接吗？ 你说when i connect to application it shows following error。如果它处于连接状态，那么为什么堆栈跟踪中有一个失败的提交？是第一次建立连接的时候吗？是在第一次提交时发生还是稍后发生？不重启就恢复了吗？
你泄露的信息太多了。我建议您下次至少删除与问题解决无关的敏感信息，例如用户名和密码。
【参考方案1】：
我也遇到过类似的错误，最简单的解决办法是用@Transactional(propagation = Propagation.REQUIRES_NEW)添加@Transaction
之后您将不会收到此错误，并且可以正常工作。
【讨论】：
【参考方案2】：原因是您已经打开了一个休眠会话并且您正在尝试执行两个查询，但请记住第一个事务的提交不会在其他事务开始之前出现。 这可能会有所帮助。 尝试在一个事务提交或使用条件时运行其他查询。
【讨论】：
【参考方案3】：在serviceimpl方法上方使用@Transactional
【讨论】：
【参考方案4】：您正在使用 @Transactional，让 Spring 为您启动、提交和回滚事务，并以声明方式处理您的事务。这样做的全部意义在于不必在代码中启动、提交和回滚事务。所以方法实现应该很简单
return (List<Login>) sessionFactory.getCurrentSession().createQuery("from Login").list();
