Spring boot inject EntityManagerFactory in configuration class

Question

I\'m using spring boot and i want to integrate spring with hibernate. I want to make a Session Factory bean for further using. But I can\'t autowire EntityManagerFactory, I can\

Answer 1

I'm not exactly sure why you want to expose both beans because as @chrylis points out, you can easily unwrap the EMF into a SF where needed.

// Some spring component
@Component
public class MyFancyComponent {
  @PersistenceContext
  private EntityManager entityManager;

  public void doSomethingFancy() {
    // public SessionFactory API
    final SessionFactory sf = entityManager
         .unwrap( Session.class ).getFactory();

    // public SessionFactoryImplementor SPI
    final SessionFactoryImplementor sfi = entityManager
         .unwrap( SessionImplementor.class ).getFactory();
  }
}
