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

Answer 1

If your datasource is bounded at the JNDI tree:

configuration.setProperty("hibernate.connection.datasource", "java:comp/env/jdbc/test");

Otherwise, if you have a DataSource object in code, which you want to use:

java.sql.Connection conn = datasource.getConnection();
Session session = sessionFactory.openSession(conn);

I would recommend the first one, to let Hibernate handle the connection lifecycle as needed. At the second approach, make sure that you close the connection when it's no longer needed.
