假如有如下程序，需要向数据库里面加如100000条数据

StatelessSession session = sessionFactory.openStatelessSession();    Transaction tx = session.beginTransaction();  ScrollableResults customers = session.getNamedQuery("GetCustomers")                                .scroll(ScrollMode.FORWARD_ONLY);  while ( customers.next() ) {       Customer customer = (Customer) customers.get(0);       customer.updateStuff(...);       session.update(customer);    }   tx.commit();  session.close();
