use*_*133 3 java spring hibernate spring-boot
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，它应该自动获取属性文件并能够创建会话工厂 bean。
我需要在一些 Dao 类中使用会话工厂和 hibernate，但是下面的简单示例重现了我遇到的问题：

我的问题是我期望 Spring Boot JPA 自动配置为我的 Hibernate DAO 自动配置和连接 SessionFactory。
SessionFactory 特定于 Hibernate，而 Spring Boot 自动装配 EntityManager 对象，这对 JPA 更通用。
在我的 Dao 对象中将 SessionFactory 交换到 EntityManager 允许我使用 Spring 的自动配置来连接所有东西。
