org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.exceptions.PersistenceException:
### Error querying database. Cause: org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot load JDBC driver class '2678A9D8A4F5FA0707A5F652001ACABE816EE484B994AE39ED963C5A4B2DA3A22B8ABA272F176A7C2C239A79A6364D41'
### The error may exist in cn/drzk/wanda/cinema/dao/form/dao/TicketsFromDao.java (best guess)
### The error may involve cn.drzk.wanda.cinema.dao.form.dao.TicketsFromDao.count
### The error occurred while executing a query
### Cause: org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot load JDBC driver class '2678A9D8A4F5FA0707A5F652001ACABE816EE484B994AE39ED963C5A4B2DA3A22B8ABA272F176A7C2C239A79A6364D41'

这个……“Could not get JDBC Connection”和“Cannot load JDBC driver class”，很明显是找不到驱动器类。一般是因为服务器下没有相应jar，不过看那一堆乱码……有可能是解码格式的问题（没遇到过），而且是用spring加载的(?)，多半是解码问题，把类名加密了。追问

是对连接进行加密了，但也进行了解密，是用的spring

追答

这个……不看代码是不知道问题在哪……虽说看了也不一定知道。
80%的可能是解密不对或在解密前就去加载类了。接下来……我无能为力……Sorry

 参考技术A 是不是加载驱动那里写错了？追问

比如呢？

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();

以上是关于java 启动jdbc 事务报错 嵌套异常的主要内容，如果未能解决你的问题，请参考以下文章

使用 JDBC 3.0 实现对嵌套事务的支持

无法提交 Hibernate 事务；嵌套异常是 org.hibernate.Transaction 异常：JDBC 提交失败

为什么MySQL JDBC不使用“启动事务”查询来启动事务？

无法打开 JPA EntityManager 进行事务处理；嵌套异常是 org.hibernate.exception.SQLGrammarException：无法获取 JDBC 连接

EF sqlite3报错 "System.Data.Entity.Core.EntityException: 在提供程序连接上启动事务时出错。有关详细信息，请参阅内部异常。
