Hibernate configuration on runtime

Question

I have hibernate.cfg.xml file.

<session-factory>

    <!-- Database connection settings -->
    <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
    <property name="connection.url"></property>
    <property name="connection.username"></property>
    <property name="connection.password"></property> 

    <!-- JDBC connection pool (use the built-in) -->
    <property name="connection.pool_size">1</property>

.....................

This is the most interesting part of file. Now i must set missing values: url, username, password. I'm trying to do in such way:

public static void SetSessionFactory() {
    try {

      AnnotationConfiguration conf = new AnnotationConfiguration().configure();
      // <!-- Database connection settings -->
      conf.setProperty("connection.url", URL);
      conf.setProperty("connection.username", USERNAME);
      conf.setProperty("connection.password", PASSWORD);
      SESSION_FACTORY = conf.buildSessionFactory();

    } catch (Throwable ex) {
      // Log exception!
      throw new ExceptionInInitializerError(ex);
    }
  }

But it just loads my configuration from hibernate.cfg.xm and do not changing any property...

url, username, passoword - are command-line arguments so i must set them on runtime.

Answer 1

Try to call conf.configure(); here.
And properties may need to have hibernate prefix like "hibernate.connection.username"
Hope it helps.

Answer 2

Try like this it is working fine

AnnotationConfiguration conf = new AnnotationConfiguration().configure("/dronehibernate.cfg.xml");

conf.setProperty("hibernate.connection.url","jdbc:mysql://localhost/PAT_DRONE_DB1");

SessionFactory sessionFactory = conf.buildSessionFactory();

Session session = sessionFactory.openSession();

List<NetworkType> channelList = session.createQuery("from NetworkType").list();
