HQL实现简单查询

@Test //查询所有记录  
    public void alluser(){  
        // TODO Auto-generated method stub  
        SessionFactory sf = null;  
        Session session = null;  
        Transaction ts = null;  
  
        try {  
            sf = HibernateUtil.getSessionFactory();  
            //用getCurrentSession创建的Session实例只属于当前线程  
            session = sf.getCurrentSession();  
            ts = session.beginTransaction();  
            Criteria criteria = session.createCriteria(User.class);  
            List users = criteria.list();  
            for(int i=0;i<users.size();i++)  
            {  
                User user =(User)users.get(i);  
                System.out.println(i+"--"+user.getUsername());  
            }  
            ts.commit();  
        } catch (HibernateException e) {  
            // TODO Auto-generated catch block  
            if(ts != null)  
            {  
                ts.rollback();  
            }  
            e.printStackTrace();  
        }   
    }  
}
