Java中使用hql,sql查询返回的list
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("PARENT_ID"); //这里的key 一定是 数据库对应的字段名才行
例如：
// 查询出数据
String hql = "select a.id as emergencyBasExeId,a.LEVEL as level,a.SEND_TIME as sender_time,a.NAME as name,a.CONTENT as content " +
",a.PROCESS_ID as processId,m.STATES as states,m.id as id,m.emergencyInfoSecondMgr.id as emergencySencondMgrId " +
" from EmergencyInfoFirstExe a, EventManage m where a.deleteFlag = 0 and a.id=m.emergencyInfoFirstExe.id ";
// 查询出数据list
List exeList = eventManageDao.notifyHqlPage(hql, pageNumber * pageSize, pageSize);
// 返回所需要的数据List
List<EventInfoView> reList = new ArrayList<EventInfoView>();
//map.get("PARENT_ID"); //这里的key 一定是 数据库对应的字段名才行
//对返回List的数据封装
for(Object exe : exeList){
EventInfoView event = new EventInfoView();
//此时，每个Object可以转换成一个Map
Map map=(Map)exe;
//然后可以使用map.get("属性名");即可取值
event.setId(map.get("id").toString());
event.setContent(map.get("content").toString());
event.setEmergencyBasExeId(map.get("emergencyBasExeId").toString());
event.setEmergencySencondMgrId(map.get("emergencySencondMgrId").toString());
event.setEmergencyTitle(map.get("emergencyTitle").toString());
event.setLevel(map.get("level").toString());
event.setName(map.get("name").toString());
event.setProcessId(map.get("processId").toString());
event.setProcessName(map.get("processName").toString());
event.setSender_time(map.get("sender_time").toString());
event.setStates(map.get("states").toString());
//....
reList.add(event);
}
