我似乎无法弄清楚为什么我的Spring Boot应用程序无法自动创建SessionFactory。据我了解，它应该自动拾取属性文件并能够创建会话工厂bean。
我需要将某些Dao类中的会话工厂与hibernate一起使用，但是下面的简单示例重现了我遇到的问题:

最佳答案
我的问题是我希望Spring Boot JPA自动配置能够为Hibernate DAO自动配置并连接SessionFactory。
SessionFactory特定于Hibernate，而Spring Boot会自动连接EntityManager对象，这对于JPA更通用。
在我的Dao对象中将SessionFactory交换到EntityManager允许我使用Spring的自动配置来连接一切。
