Room需要先實現序列化implements Serializable

ArrayList<Room> list=null;
roomList = getDaoRoomListData(filterParams, sort, order, skip, limit);
List<String> ridList = new ArrayList();
//

=========================================================

for (Room roomr : roomList) {

String strKeyrid=key+roomr.getRid();
Map<String, ?> parse = Document.parse(JSON.toJSONString(roomr));
helper.setRoomone(strKeyrid,roomr);//以一個實體存進緩衝

}
Map redisMap=new HashMap();
helper.setRoomList(keys,roomList);//以列表存進緩衝

 

===============緩衝擷取實體,經過序列化後就可以直接顯示了=========================

 

if (roomListOne.size() > 0) {
Room room=roomListOne.get(0);
String roomid=room.getRid();
String keyroomid=key+roomid;
Room roomone=helper.getRoomone(keyroomid);
if(null!=roomone){
roomList.add(roomone);
flagRoomOne=false;
}
}

================擷取列表,經過序列化後就可以直接顯示了==================

roomList =helper.getRoomList(keys);
