接前面的例子:http://blog.csdn.net/kunshan_shenbin/archive/2008/09/03/2874375.aspx

测试代码以下:

1.package com.hb3.pack_22;
2.
3.import java.io.IOException;
4.import java.sql.SQLException;
5.import java.util.List;
6.
7.import org.hibernate.Query;
8.import org.hibernate.Session;
9.import org.hibernate.SessionFactory;
10.import org.hibernate.cfg.Configuration;
11.
12.import com.hb3.pack_22.model.User;
13.
14.public class BusinessService {
15.
16.    public static void main(String[] args) throws IOException, SQLException {
17.
18.        Configuration config = new Configuration().configure();
19.        SessionFactory sessionFactory = config.buildSessionFactory();      
20.        Session session = sessionFactory.openSession();
21.
22.
23.        String hql = "from com.hb3.pack_22.model.User";
24.
25.        Query query = session.createQuery(hql);
26.        List<?> users = query.list();
27.
28.        for(int i = 0; i < users.size(); i++) {
29.            User user = (User) users.get(i);
30.            System.out.println(user.getName());
31.        }
32.
33.        query = session.createQuery(hql);
34.        users = query.list();
35.
36.        for(int i = 0; i < users.size(); i++) {
37.            User user = (User) users.get(i);
38.            System.out.println(user.getName());
39.        }
40.
41.
42.        session.close();
43.        sessionFactory.close();
44.    }
