无法从 LocalContainerEntityManagerFactoryBean (Hibernate OGM Pr

Question

我正在尝试使用Hibernate OGM持久性提供程序从Spring的LocalContainerEntityManagerFactoryBean检索JPA EntityManager，但是当我尝试从注入的EntityManagerFactory创建EntityManager时，我收到以下错误：

我正在尝试在Java EE容器之外实现这一点，根据我的研究，我相信这是可能的。我尝试升级/降级Hibernate和Spring版本，认为这可能是兼容性问题，但没有任何运气。任何指导将不胜感激！

Answer 1

你应该直接注入 EntityManager，而不是注入 EntityManagerFactory ：

@PersistenceContext
private EntityManager entityManager;

Answer 2

我怀疑你的类路径上有多个不同版本的Hibernate ORM，而Hibernate OGM采用了错误的版本。这就是为什么该方法getSessionFactory()具有意外签名的原因。

更新：Spring Boot 2.2.0 预计 Hibernate ORM 5.4.6.Final，OGM 使用 5.3.6.Final
