以上查询涉及我正在处理的项目：

项目：

我有一个使用SpringBoot和hibernate的简单的基于REST的API项目，在这里我需要使用GET和POST请求构建一个注册和登录机制。每当我试图发出POST请求来创建资源(在本例中是创建一个新用户)时，我就会在POSTMAN和Eclipse上得到以下错误：

我使用POSTMAN发出的POST请求

代码语言：javascript
复制
{
    "userId": "12345",
    "pin": "1234"
}

投递请求时邮递员的错误

代码语言：javascript
复制
    {
    "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"
}

将@SpringBootApplication更改为

代码语言：javascript
复制
@SpringBootApplication(exclude=HibernateJpaAutoConfiguration.class)

随着Hibernate 5.2的发布，SessionFactory扩展了EntityManagerFactory接口。这就导致了SessionFactory也是一个EntityManagerFactory。

在以前的hibernate版本中，情况并非如此。

简单的解决方案是将hibernate版本降级为< 5.2版本，因为Spring5.0没有解决方案(Spring5.1中将有)。

有关更多细节，您可以参考1 2

编辑：

因此编写exclude=HibernateJpaAutoConfiguration.class时

@SpringBootApplication

将不考虑该特定类的进一步执行。正如您在图像中看到的那样，HibernateJpaAutoConfiguration已经实现了一些不需要为其配置任何东西或使其易于使用的类(这些类可能实现了其他类)，例如，LocalContainerEntityManagerFactoryBean.class。由于您已经排除了类，所以您必须手动执行HibernateJpaAutoConfiguration.class为您所做的事情。
