hibernate多表查询
涉及到3张表联查
String selfsql = "SELECT t.id as nid,t.playName as nameid,t.mapId,t.otherPlayName,t.otherMapId,t.time,t2.cityname,t3.playName FROM T_Log_Traffic as t,T_Map_MapInfo as t2,T_User_UserInfo as t3 where t.playName = '"+userId+"' and t.otherMapId = t2.mapId and t3.userId=t.otherPlayName";
需要8个字段，都取出来了，请问是再新建一个持久化类还是分别用原来的3个，具体怎么做，谢谢
[解决办法]
你可以对以上字段在建个javabean，用的时候比较方便，也可不建，如果要显示这些信息，直接用数组的形式读取就好了，
