I have built my application on Hibernate, but now I need to get EntityManager for one third-party module.
Could you please give me some hints how to get JPA objects from Hibernate?
(in my case I have SessionFactory and need EntityManager)

Hibernate provides implementation of JPA interfaces EntityManagerFactory and EntityManager . EntityManagerFactory provides instances of EntityManager for connecting to same database. All the instances are configured to use the same setting as defined by the default implementation.
unwrap(SessionFactory. class); In the first line, I get the current Hibernate Session from the EntityManager. I, therefore, call the unwrap method on the EntityManager and provide the Session class as a parameter.
Steps to persist an entity object. Persistence - The Persistence is a bootstrap class which is used to obtain an EntityManagerFactory interface. createEntityManagerFactory() method - The role of this method is to create and return an EntityManagerFactory for the named persistence unit.
I found this in Hibernate 5.2
Session session = HibernateUtil.getSessionFactory().openSession();
EntityManager em = session.getEntityManagerFactory().createEntityManager();
