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

When you say

But I can't autowire EntityManagerFactory

does it fail to compile or throw an exception at run-time? If the latter, what does the stack-trace say?

One possible solution/work around might be to inject an em into the configuration instead of the em factory, using the @PersistenceContext annotation:

@Configuration
@EnableTransactionManagement
public class DatabaseConfiguration {

    @PersistenceContext
    private EntityManager entityManager;

    @Bean
    public SessionFactory getSessionFactory() {
        // no need to check for null here because if the unwrap fails, it will do
        // so by throwing a PersistenceException rather than returning null.
        return entityManager.unwrap( Session.class ).getFactory();
    }
}
