关于网站签到功能的设计

1，最近网站要上一个签到的功能，一个多游戏的平台，每种游戏的官网都有签到功能，设计打算把数据放到平台。

2，首先要设计签到表，这里直接给出过了一遍dba，需求人员，设计人员脑子的结果：

最精彩的地方是signHistory的设计，直接存成bigint,通过转换成二进制来记录签到的历史；

3，预览图

4，功能抽取

非常明显，只有三个主要的功能，第一个签到之前的登录；第二个，签到；第三个，领取礼包；

功能	功能概述	功能的具体逻辑	接口方法设计
登录之前的查询	通过查询，以前签过到的，显示签到历史；没有签过到的，神马也不显示；	查询dt_sign表，通过gid和uid查询，如果查询到，返回签到信息，如果没有查到，返回提示信息	SignMsg loginQuery(int gid,int uid)
签到	点击签到，如果当天已经签过到了，提示已经签过到了；如果从来没有签过到，插入数据，把积分设置为1，连续签到次数设置为1，最后修改时间设置为当天，历史为1；如果今天没有签过到，首先计算出有多少天没签到了，如果是昨天签了的，连续签到次数加1，历史左移一位，积分按照积分规则加上；如果超过两天没有签到，连续签到次数设置为1，历史左移天数位，积分加上签到单次的积分，时间为当前的修改时间；	首先查询dt_sign，按照gid和uid，如果没查到，插入记录；查到了，判断最后修改时间，做相应的处理；	SignMsg todaySign(int gid,int uid)
领取礼包	点击领取礼包，如果分数够，减去积分，允许该用户领取礼包；如果分数不过，提示积分不够；	点击领取礼包，如果分数够，减去积分，允许该用户领取礼包；如果分数不过，提示积分不够；	SignMsg getGiftPack(int gid,int uid,int score)

5，具体实现

jdbc实现：
