Oracle中 oriteria 接口的简单使用

<em><span style="font-size:18px;">	Session session=HibernateUtil.getCurrentSession();
		Transaction ts=null;
		try{
			ts=session.beginTransaction();
			
			Criteria cri=session.createCriteria(Employee.class).setMaxResults(2).addOrder(Order.desc("id")); 
			
			List<Employee> list=cri.list();
			
			for(Employee e:list){
				System.out.println(e.getEmail());
			}
			
			ts.commit();
			
		}finally{
			//关闭Sesion
			if(session!=null&&session.isOpen()){
				session.close();
			}
		}</span></em>
