先看以下代码

List receiveList = offDao.findByHql(hql, page, row);
if(receiveList.size()>0&&receiveList!=null){
    Iterator it = receiveList.iterator();
    while(it.hasNext()){
        Object[] object = (Object[])it.next();
        OffAnnouncementReceive offReceive = new OffAnnouncementReceive();
        String consigneeid=object[0].toString();
        String flgs = object[1].toString();
        String sendmail = object[2].toString();
        String sendPeo = object[4].toString();
        Date sendDate = (Date)object[5];
        String announcementReceiveId = object[6].toString();
        offReceive.setAnnouncementReceiveId(announcementReceiveId);
        offReceive.setConsigneeId(consigneeid);
        offReceive.setSendmailId(sendmail);
        if(sendDate!=null&&!sendDate.equals("")){
            offReceive.setSendDate(sdf.format(sendDate));
        }
    }
}

使用sql返回的list<Object>转成需要的实体对象，看下面的Map的使用,很方便（需要将Query对象setResultTransformer）： 

List list = session.createSQLQuery(sql) 
.setResultTransformer( 
Transformers.ALIAS_TO_ENTITY_MAP) 
.list(); 
//此时，每个Object可以转换成一个Map 
Map map = (Map) list.get(i); 
map.get("student_id");  //这里的key 一定是 数据库对应的字段名才行
