hql语句里日期比较

 Date date=Calendar.getInstance().getTime();
  Date date1=Calendar.getInstance().getTime();
  String hql ="From Student s where 1=1 "
              +" and s.time != null "
              +" and s.time >:date "
              +" and s.time <=:date1 ";
    Query query=sessionFactory.createQuery(hql);
    query.setTimestamp("date", date);//注意这里，用setTimestampe，不要用setDate
    query.setTimestamp("date1", date1);
   List<Student> list=query.list();
