1.添加 投票选项到 redis的  List 和HashMap

list    key  ==> tomas:vote:vote_item:%S:list   (PS. %S=voteId)

value==> {video_hashmap_key} 

map  key  ==> tomas:vote:vote_item:%S:hashMap  (PS. %S=voteId)

         value==> {{id=01;name=001,title=0002,投票数=33.....},{.....}}  

Map<String, String> map = new HashMap<String, String>();
//Long size = voteService.getCountNewYearVideos(null, voteId);
map.put("ac", ac);
map.put("vid", "***");
map.put("title", content.getTitle());
map.put("time", content.getSortDate().getTime());
map.put("conver", content.getTitleImg());
map.put("up_id", content.getUser().getId());
map.put("up_name", content.getUsername());
map.put("up_icon", content.getUser().getUserImg());
map.put("voteCount", "0");
//添加视频 也就是投票选项
Long result = voteService.addVoteItem(null, voteId, map);

/**

 *
 * @param jedis
 * @param voteId 活动id
 * @param params ac : acId  vid: vid  name:title cover:封面 up:uperName
 * @return int 添加完成视频总数
 */
@Override
public Long addVoteItem(Jedis jedis, Integer voteId, Map<String, String> params) {

    String video_list_key = this.getFormatKeyStr(ALL_VIDEO_LIST, voteId);
    String video_hashmap_key = this.getFormatKeyStr(NEW_YEAR_VIDEO_INFO_MAP, voteId, params.get("ac"));
    if (this.isExistInVoteItem(jedis, voteId, params.get("ac"))) {
        return 0L;
    }
    if (StringUtils.isEmpty(params.get("vid"))) {
        jedis.incr(getFormatKeyStr(ALL_VIDEO_LIST_INDEX, voteId));   //自增id
    }
    //添加视频信息到分页list lrange(用)  并且吧map的key当作list的vlaue分页是查询出list
    Long all_size = jedis.lpush(video_list_key, video_hashmap_key);
    //添加视频信息到Hashmap
    jedis.hmset(video_hashmap_key, params);
    //设置key过期时间
