If you are using Spring 4+, you should use SessionFactory. Also, you need these jars: commons-pool, commons-dbcp.

This is a sample code that I made, I hope it helps you:

public class EmployeeDAOImpl implements EmployeeDAO{

    private SessionFactory sessionFactory;

    @Override
    public void saveEmployee(Employee e) {
        Session session = this.sessionFactory.openSession();
        Transaction tx = session.beginTransaction();
        session.persist(e);
        tx.commit();
        session.close();
    }

    public SessionFactory getSessionFactory() {
        return sessionFactory;
    }

    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }

}

applicationContext.xml:

     
        
        
        
        
    

      
        

        
        
            employee.hbm.xml
        
        

        
            
                org.hibernate.dialect.Oracle9Dialect
                update
                true
