Java 春季及；Hibernate c3p0错误无法完成架构验证

在我们的项目中，我们使用Spring和Hibernate。在服务器和其他开发人员计算机上，项目成功运行。然而，在我用SVN更新了我的项目之后，我得到了一个错误列表，它已经关闭了，我有两天没能解决它。我读过很多关于它的文章，并尝试过，但问题并没有解决。甚至，我已经完全删除了项目，并再次签出，恢复数据库，但没有任何改变。MySql已检查并正常工作

这里有错误：

我是Spring和Hibernate的新手，在阅读文章时，这些代码块很重要，应该加以管理。如果需要任何其他代码块，请对其进行注释

您应该在数据源bean中放入以下行

<property name="driverClass" value="${jdbc.driverClassName}" />

应该有更多的堆栈跟踪，但我猜您的类路径中没有MySQL的JAR文件。是的，有更多的堆栈跟踪，我刚刚在这里写下了错误消息。Maven Dependencies中有mysql-connector-java-5.1.12.jar。也许您的项目中没有包含mysql JDBC jar？5年后，我只能说这是一段美好的时光，我一直在从事一个定制t-sirts的项目！一个人应该具备所有的理论知识。。。顺便说一下，我在控制台中有一条消息：`name:MySQL版本：5.0.96-community-nt-major:5-minor:0 2013-01-16 08:02:59907信息[org.hibernate.cfg.SettingsFactory]-驱动程序->name:MySQL-AB-JDBC驱动程序版本：MySQL-connector-java-5.1.12（版本：${bzr.Revision id}）大调：5小调：1`这会给我带来麻烦吗？试试：hibernate.dialen=org.hibernate.dialen.mysqldialen而不是mysql5dialen
