Retrieve auto-detected hibernate dialect
Hibernate has the option to auto-detetect the hibernate.dialect
. How can I retrieve that auto-detected v开发者_开发问答alue? I was unable to find any information on this.
You can retrieve it from the SessionFactory but you'll need to cast it to SessionFactoryImplementor first:
SessionFactory sessionFactory = ...; // you should have this reference
Dialect dialect = ((SessionFactoryImplementor) sessionFactory).getDialect();
The above will retrieve the dialect instance currently being used by session factory, which is the auto detected instance if it wasn't explicitly specified via properties.
From Hibernate 5.2+ the most appropriate way to get Dialect is:
EntityManager em ...
Session session = em.unwrap(Session.class);
SessionFactory sessionFactory = session.getSessionFactory();
Dialect dialect = ((SessionFactoryImplementor) sessionFactory).getJdbcServices().getDialect();
