hibernate查询API

查询表里面的所有记录

1、通过Query对象查询

session = HibernateUtils.getSession();
            ts = session.beginTransaction();
            Query query = session.createQuery("from User");
            List<User> list = query.list();
            int i = 0;
            for (User user : list) {
                i ++;
                System.out.println(i + user.toString());
            }

3、通过SQLQuery对象实现

SQLQuery sq = session.createSQLQuery("select * from t_user");
            sq.addEntity(User.class);
            List<User> list = sq.list();
            int i = 0;
            for (User user : list) {
                System.out.println(++i + user.toString());
            }
