【中文标题】sessionFactory bean 在“持久性”元素上失败【英文标题】：sessionFactory bean fail on 'persistence' element 【发布时间】：2013-01-14 14:07:08 【问题描述】：

首先，我知道有很多关于创建 sessionFactory bean 的问题，但不幸的是我没有找到任何适合我的解决方案。

这是堆栈跟踪中的整个异常：

感谢您的宝贵时间和建议，我真的很感激。

【问题讨论】：

【参考方案1】：

persistence.xml 不是 Hibernate 映射（即.hbm.xml）。

此外，由于您使用SessionFactory（不是JPA），因此您根本不应该使用persistence.xml。

您需要从您的配置中删除mappingLocations，并改为配置AnnotationSessionFactoryBean 的适当属性：

packagesToScan 或 annotatedClasses 配置实体的位置 hibernateProperties 代表hibernate.show_sql、hbm2ddl.auto 等等

您也不需要hibernate.connection.* 属性，因为您已经在DriverManagerDataSource 中配置了它们。

【讨论】：

感谢您的回复。但是persistence.xml可以在哪里使用呢？ persistence.xml 用于需要通过 JPA API 使用 Hibernate（即通过 EntityManager）。但即使在这种情况下，最新版本的 Spring 也允许您省略 persistence.xml。

以上是关于sessionFactory bean 在“持久性”元素上失败的主要内容，如果未能解决你的问题，请参考以下文章

SessionFactory

自动装配的 sessionFactory 对象为空

spring整合hibernate，在获取sessionFactory的时候报错，求解决办法！！
