You can do it programmatically.

hibernate.cfg.xml should be as following.

    
    
        
            org.hibernate.transaction.JDBCTransactionFactory
        
    

dbConnection.properties

connection.driver_class=org.postgresql.Driver
connection.username=postgres
connection.password=postgres

And when creating the SessionFactory you can do the following.

Properties dbConnectionProperties = new Properties();
try {
    dbConnectionProperties.load(ClassLoader.getSystemClassLoader().getResourceAsStream("dbConnection.properties"));
} catch(Exception e) {
    // Log
}

SessionFactory sessionFactory = new Configuration().mergeProperties(dbConnectionProperties).configure().buildSessionFactory();
