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


1.需求原型图


2.查询签到记录


3.进行签到


4.技术实现方案

  • SpringBoot

  • MySQL


数据库表结构


1.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',  `param1` int(2) DEFAULT NULL COMMENT '预留字段1',  `param2` int(4) DEFAULT NULL COMMENT '预留字段2',  `param3` int(11) DEFAULT NULL COMMENT '预留字段3',  `param4` varchar(20) DEFAULT NULL COMMENT '预留字段4',  `param5` varchar(32) DEFAULT NULL COMMENT '预留字段5',  `param6` varchar(64) DEFAULT NULL COMMENT '预留字段6',  PRIMARY KEY (`id`) USING BTREE,  UNIQUE KEY `uk_zh_sign_in_buno` (`bu_no`),  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';

2.签到记录历史表

CREATE TABLE `zh_sign_in_hist` (  `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 NULL 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',  `param1` int(2) DEFAULT NULL COMMENT '预留字段1',  `param2` int(4) DEFAULT NULL COMMENT '预留字段2',  `param3` int(11) DEFAULT NULL COMMENT '预留字段3',  `param4` varchar(20) DEFAULT NULL COMMENT '预留字段4',  `param5` varchar(32) DEFAULT NULL COMMENT '预留字段5',  `param6` varchar(64) DEFAULT NULL COMMENT '预留字段6',  PRIMARY KEY (`id`) USING BTREE,  UNIQUE KEY `uk_zh_sign_in_hist_cid_signindate` (`customer_id`,`sign_in_date`) USING BTREE,  KEY `key_zh_sign_in_hist_buno` (`bu_no`) USING BTREE) ENGINE=InnoDB  DEFAULT CHARSET=utf8mb4 COMMENT='用户签到历史表';

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

别忘记点个在看，咱们下篇见！
