前言
最近在做社交业务，用户进入APP后有签到功能，签到成功后获取相应的奖励：
项目状况：前期尝试业务阶段；
特点：
- 快速实现（不需要做太重，满足初期推广运营即可）
- 快速投入市场去运营
用户签到：
- 用户在每次启动时查询签到记录（规则：连续7日签到从0开始，签到过程中有断签从0开始）
- 如果今日未签到则提示用户可以进行签到
- 用户签到获取相应的奖励
提到签到，脑海中首先浮现特点：
- 需要记录每位用户每天的签到情况
- 查询时根据规则进行签到记录情况
需求&流程设计&技术实现方案
- 需求原型图
- 查询签到记录
- 进行签到
- 技术实现方案
- SpringBoot
- MySQL
数据库表结构
- 签到记录最新表

- 签到记录历史表

测试
- 模拟用户进行签到
- 进行请求
- 查看数据库结果
- 模拟用户查询签到记录
- 进行请求
总结
- 亮点：实现业务连续签到，断签以及奖励的业务
- 注意点：基于数据库查询做的，在进行签到接口需要用redis锁防止并发操作
- 后续会持续分享更多业务中的亮点
