Try enabling HibernateJpaSessionFactoryBeanin your Spring configuration.
尝试HibernateJpaSessionFactoryBean在您的 Spring 配置中启用。
@Bean
public HibernateJpaSessionFactoryBean sessionFactory() {
return new HibernateJpaSessionFactoryBean();
}

By Spring configuration I mean a class annotated with @Configurationannotation or @SpringBootApplication(it is implicitly annotated with @Configuration).
通过 Spring 配置，我的意思是用@Configurationannotation 或@SpringBootApplication(它隐式地用 注释@Configuration)注释的类。

Since version 2.0, JPA provides easy access to the APIs of the underlying implementations. The EntityManagerand the EntityManagerFactoryprovide an unwrapmethod which returns the corresponding classes of the JPA implementation.
从 2.0 版开始，JPA 提供了对底层实现 API 的轻松访问。的EntityManager和EntityManagerFactory提供unwrap返回JPA实现的相应的类的方法。
In the case of Hibernate, these are the Sessionand the SessionFactory.
在 Hibernate 的情况下，这些是Session和SessionFactory。
SessionFactory sessionFactory = entityManagerFactory.unwrap(SessionFactory.class);
