How to setup hibernate.cfg.xml via Java code?

Well, I'm working on an application which syncs two databases. I need to setup hibernate.cfg.xml for 2 databases. Postgresql and Firebird. I'd like to create a generic class to set up my hibernate.cfg.xml.

I'd like to do something like this: 

currentSessionFactory = new AnnotationConfiguration()
.setProperty("hibernate.dialect", entity.getDialect())
.setProperty("hibernate.connection.driver_class", entity.getDriverClass())

I need a new hibernate.cfg.xml for the second database but I can't set up it via xml, I need to do it through Java code.

How should I do it ?

You can use Hibernate Configuration class to replace the hibernate.cfg.xml alltogether:

Configuration configuration = new Configuration();
configuration.addAnnotatedClass(Entity1.class);
ServiceRegistry serviceRegistry
            = new StandardServiceRegistryBuilder()
                .applySettings(configuration.getProperties()).build();            
sessionFactory = configuration.buildSessionFactory(serviceRegistry);

The Configuration class allows you to:

  • add classes
  • add properties

Here you have an example on GitHub.
