Failure to retrieve EntityManager from LocalContainerEntityManagerFactoryBean (Hibernate OGM Provider)

Question

I am trying to retrieve a JPA EntityManager from Spring's LocalContainerEntityManagerFactoryBean using the Hibernate OGM persistence provider but I am getting the following error when I attempt to created an EntityManager from the injected EntityManagerFactory:

I am trying to implement this outside of a Java EE container, which I believe is possible based on what I have researched. I have tried upgrading/downgrading Hibernate and Spring versions, thinking it may be a compatibility issue, but have not had any luck. Any guidance would be much appreciated!

You should inject EntityManager directly instead of injecting EntityManagerFactory :

@PersistenceContext
private EntityManager entityManager;

I don't think this is possible for me, as I am not running inside a JavaEE container. Thanks though. – chejohn131 Jun 01 '20 at 19:51

I suspect there are multiple different versions of Hibernate ORM on your classpath and Hibernate OGM is taking the wrong one. That's why the method getSessionFactory() has an unexpected signature.

UPDATE: Spring Boot 2.2.0 expects Hibernate ORM 5.4.6.Final, OGM uses 5.3.6.Final

Hmm...I suspected this may be the issue, but I've completely searched my maven dependency stack and only Hibernate 5.3.6 is referenced anywhere. – chejohn131 Jun 01 '20 at 19:54
