SpringBoot 签到奖励实现方案的示例代码

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

CREATE TABLE `zh_sign_in` (
 `id` bigint(20) NOT NULL AUTO_INCREMENT,
 `bu_no` varchar(32) DEFAULT NULL COMMENT '业务编码',
 `customer_id` varchar(32) DEFAULT NULL COMMENT '签到用户编码',
 `sign_in_date` datetime DEFAULT NULL COMMENT '签到日期(单位精确到日)',
 `reward_money` int(11) DEFAULT NULL COMMENT '本次签到奖励金币个数',
 `continuite_day` int(2) DEFAULT '1' COMMENT '连续签到天数（A:7天内如果有断签从0开始 B:7天签满从0开始）',
 `create_time` datetime DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
 `update_time` datetime DEFAULT CURRENT_TIMESTAMP COMMENT '更新时间',

 UNIQUE KEY `uk_zh_sign_in_cid_signindate` (`customer_id`,`sign_in_date`) USING BTREE
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='用户签到表';

签到记录历史表

CREATE TABLE `zh_sign_in_hist` (

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
