How can I set Datasource when I'm creating Hibernate SessionFactory?

Question

I\'m creating SessionFactory and I have my datasource as object in code where I\'m creating SessionFactory, but i cannot set datasource to Hibernate Configuration object. So

Luiggi Mendoza's answer is why my search sent me here, but I figure I should give my version because I spent quite some time looking around for how to do this - it sets it up with the Spring in-memory database for testing, a SessionContext and the hbm.xml in case you're not using annotations:

/**
 * Instantiates a H2 embedded database and the Hibernate session.
 */
public abstract class HibernateTestBase {

    private static EmbeddedDatabase dataSource;
    private static SessionFactory sessionFactory;
    private Session session;

    @BeforeClass
    public static void setupClass() {
        dataSource = new EmbeddedDatabaseBuilder().
                setType(EmbeddedDatabaseType.H2).
                addScript("file:SQLResources/schema-1.1.sql").
                addScript("file:SQLResources/schema-1.2.sql").
                build();
        Configuration configuration = new Configuration();
        configuration.addResource("hibernate-mappings/Cat.hbm.xml");
        configuration.setProperty("hibernate.dialect",
                "org.hibernate.dialect.Oracle10gDialect");
        configuration.setProperty("hibernate.show_sql", "true");
        configuration.setProperty("hibernate.current_session_context_class",
                "org.hibernate.context.internal.ThreadLocalSessionContext");
        StandardServiceRegistryBuilder serviceRegistryBuilder =
                new StandardServiceRegistryBuilder();
        serviceRegistryBuilder.applySetting(Environment.DATASOURCE, dataSource);
        serviceRegistryBuilder.applySettings(configuration.getProperties());
        StandardServiceRegistry serviceRegistry =
                serviceRegistryBuilder.build();
        sessionFactory = configuration.buildSessionFactory(serviceRegistry);
        sessionFactory.openSession();
    }

    @AfterClass
    public static void tearDown() {
        if (sessionFactory != null) {
            sessionFactory.close();
        }
        if (dataSource != null) {
            dataSource.shutdown();
        }
    }

    @Before
    public final void startTransaction() {
        session = sessionFactory.getCurrentSession();
        session.beginTransaction();
    }

    @After
    public final void rollBack() {
        session.flush();
        Transaction transaction = session.getTransaction();
        transaction.rollback();
    }

    public Session getSession() {
        return session;
    }

}

and you'll need these:

  org.springframework
  spring-jdbc
  4.1.6.RELEASE


  com.h2database
  h2
  1.4.184
  test
