Hibernate configuration example with in-memory H2 DB for ad-hoc testing

    Sometimes I like to play a little bit with Hibernate. I do not want to spend much time on configuration or DB schema creation so I keep prepared piece of code.

Here it is:

public class HibernateConfig {

 public static void main(String[] args) throws Exception {
  SessionFactory sessionFactory = new Configuration()
  .addAnnotatedClass(Entity.class)
  .setProperty("hibernate.dialect", "org.hibernate.dialect.H2Dialect")
  .setProperty("hibernate.connection.url", "jdbc:h2:mem:test;DB_CLOSE_DELAY=-1")
  .setProperty("hibernate.current_session_context_class", "thread")
  .setProperty("hibernate.show_sql", "true")
  .setProperty("hibernate.hbm2ddl.auto", "create")
  .buildSessionFactory();
  
  Session session = sessionFactory.getCurrentSession();
  session.beginTransaction();

  // PLAY HERE 

  session.getTransaction().commit();
 }
}

and my dependencies from pom.xml:
