Spring 4 + Hibernate 5 = org.springframework.orm.jpa.EntityManagerHolder无法强制转换为org.springframework.orm.hibernate5.SessionHolder

好吧，在开始一个新的java项目并集成spring / hibernate等工具时，我是一个完全的初学者。事实上，这是我第一次这样做。 所以我相信这些错误对你们来说是显而易见的。

Guessings：

• 我期待的会议工厂不是spring注入的工厂。
• 错误的依赖关系。

Answer 1

你使用Spring-Boot吗？ 是这样，在我的情况下问题是@EnableAutoConfiguration – 使用exclude = HibernateJpaAutoConfiguration.class
