本文分享了一个新手在使用Hibernate过程中遇到的关于配置文件中dialect属性大小写敏感的问题，并给出了正确的解决方案。

新手第一次学习hibernate，当我运行程序是老是出现异常org.hibernate.HibernateException，反复查看程序代码，仍然找不出问题所在。最后，上网goolge一下发现了在hibernate.cfg.xml下 <property name="dialect">org.hibernate.dialect.MYSQL5Dialect</property>出现异常是大小写的问题应该为org.hibernate.dialect.MySQL5Dialect，再到docs下验证，果然如此。

最后，得出结论，大小写要注意，尽量对照docs文档，最好是从docs中copy代码。

Java中Hibernate框架的多数据库支持配置
AI开发架构师

在企业级应用开发中，支持多数据库环境是常见需求。Hibernate作为Java持久化层的核心框架，通过标准化的ORM（对象关系映射）机制屏蔽底层数据库差异。数据库方言（Dialect）的工作原理与配置方法多数据源（DataSource）的管理策略连接池（Connection Pool）的优化配置跨数据库事务处理与隔离级别设置传统XML配置与Spring Boot自动配置的差异对比背景介绍：明确技术目标与核心概念核心概念与联系：剖析数据库方言、数据源、连接池的架构关系配置原理与实现步骤。

<br /><br />更改springHibernate.xml中<br />因为引的是class12所以是oracle9的驱动包，因此这个地方应该是如下<br /><prop key="hibernate.dialect"> org.hibernate.dialect.Oracle9Dialect </prop>
