【中文标题】SpringBoot Rest API 中的 EntityManager 和 SessionHolder 错误【英文标题】：EntityManager and SessionHolder error in SpringBoot Rest API 【发布时间】：2019-07-28 00:07:31 【问题描述】：以上查询是关于我正在从事的项目：
项目：
我有一个使用 SpringBoot 和 hibernate 的简单的基于 REST 的 API 项目，我需要使用 GET 和 POST 请求构建注册和登录机制。 每当我尝试发出 POST 请求以创建资源（在这种情况下创建一个新用户）时，我在 POSTMAN 和 Eclipse IDE 上都会收到以下错误：
我使用 POSTMAN 发出的 POST 请求
"userId": "12345",
"pin": "1234"
发出 POST 请求时 POSTMAN 出错
"timestamp": 1551809931747,
"status": 500,
"error": "Internal Server Error",
"exception": "java.lang.ClassCastException",
"message": "org.springframework.orm.jpa.EntityManagerHolder cannot be cast to org.springframework.orm.hibernate4.SessionHolder",
"path": "/employee/register"

【问题讨论】：
EntityManagerHolder.class 和 SessionHolder.class 可能会有所帮助，因为这两个在异常中被引用。
但是我在哪里使用它们？你能提供一个解决方案吗？
删除你的配置并简单地重写你的 DAO 以使用EntityManager。
【参考方案1】：
将@SpringBootApplication 更改为
@SpringBootApplication(exclude=HibernateJpaAutoConfiguration.class)
随着 Hibernate 5.2 的发布，SessionFactory 扩展了 EntityManagerFactory 接口。这导致 SessionFactory 也成为 EntityManagerFactory。
在以前的休眠版本中，情况并非如此。
简单的解决方案是将休眠版本降级为
你可以参考12这些了解更多详情
编辑：
当你写exclude=HibernateJpaAutoConfiguration.class作为结果
@SpringBootApplication
不会考虑进一步执行该特定类。正如您在图片中看到的HibernateJpaAutoConfiguration 已经实现了一些您不需要配置任何东西或使其易于使用的类（可能实现其他类），例如LocalContainerEntityManagerFactoryBean.class。由于您已经排除了课程，因此您必须手动执行 HibernateJpaAutoConfiguration.class 为您完成的事情。
【讨论】：
非常感谢@Romil。我已经做到了。但我不知道为什么。除了这个改变，我还必须做出一些特定的改变，比如从 DBConfiguration.Java 文件中删除 HibernateTransactionManager 代码，并添加一个 Bean 来创建像这样的 EntityManager --public LocalContainerEntityManagerFactoryBean entityManagerFactory() 。我不知道为什么我必须做出这些改变。你能帮我解决这个问题吗？以上是关于SpringBoot Rest API 中的 EntityManager 和 SessionHolder 错误的主要内容，如果未能解决你的问题，请参考以下文章
