前言

最近在做社交業務，用戶進入APP后有簽到功能，簽到成功后獲取相應的獎勵：

項目狀況：前期嘗試業務階段；

特點：

快速實現（不需要做太重，滿足初期推廣運營即可） 快速投入市場去運營

用戶簽到：

用戶在每次啟動時查詢簽到記錄（規則：連續7日簽到從0開始，簽到過程中有斷簽從0開始） 如果今日未簽到則提示用戶可以進行簽到 用戶簽到獲取相應的獎勵

提到簽到，腦海中首先浮現特點：

需要記錄每位用戶每天的簽到情況 查詢時根據規則進行簽到記錄情況

需求&流程設計&技術實現方案

需求原型圖

查詢簽到記錄

進行簽到

技術實現方案

SpringBoot MySQL

數據庫表結構

簽到記錄最新表

CREATE TABLE `zh_sign_in` ( `id` bigint(20) NOT NULL AUTO_INCREMENT, `bu_no` varchar(32) DEFAULT NULL COMMENT ’業務編碼’, `customer_id` varchar(32) DEFAULT NULL COMMENT ’簽到用戶編碼’, `sign_in_date` datetime DEFAULT NULL COMMENT ’簽到日期(單位精確到日)’, `reward_money` int(11) DEFAULT NULL COMMENT ’本次簽到獎勵金幣個數’, `continuite_day` int(2) DEFAULT ’1’ COMMENT ’連續簽到天數（A:7天內如果有斷簽從0開始 B:7天簽滿從0開始）’, `create_time` datetime DEFAULT CURRENT_TIMESTAMP COMMENT ’創建時間’, `update_time` datetime DEFAULT CURRENT_TIMESTAMP COMMENT ’更新時間’, `param1` int(2) DEFAULT NULL COMMENT ’預留字段1’, `param2` int(4) DEFAULT NULL COMMENT ’預留字段2’, `param3` int(11) DEFAULT NULL COMMENT ’預留字段3’, `param4` varchar(20) DEFAULT NULL COMMENT ’預留字段4’, `param5` varchar(32) DEFAULT NULL COMMENT ’預留字段5’, `param6` varchar(64) DEFAULT NULL COMMENT ’預留字段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=’用戶簽到表’;

簽到記錄歷史表

CREATE TABLE `zh_sign_in_hist` ( `id` bigint(20) NOT NULL AUTO_INCREMENT, `bu_no` varchar(32) DEFAULT NULL COMMENT ’業務編碼’, `customer_id` varchar(32) DEFAULT NULL COMMENT ’簽到用戶編碼’, `sign_in_date` datetime NULL DEFAULT NULL COMMENT ’簽到日期(單位精確到日)’, `reward_money` int(11) DEFAULT NULL COMMENT ’本次簽到獎勵金幣個數’, `continuite_day` int(2) DEFAULT ’1’ COMMENT ’連續簽到天數（A:7天內如果有斷簽從0開始 B:7天簽滿從0開始）’, `create_time` datetime DEFAULT CURRENT_TIMESTAMP COMMENT ’創建時間’, `update_time` datetime DEFAULT CURRENT_TIMESTAMP COMMENT ’更新時間’, `param1` int(2) DEFAULT NULL COMMENT ’預留字段1’, `param2` int(4) DEFAULT NULL COMMENT ’預留字段2’, `param3` int(11) DEFAULT NULL COMMENT ’預留字段3’, `param4` varchar(20) DEFAULT NULL COMMENT ’預留字段4’, `param5` varchar(32) DEFAULT NULL COMMENT ’預留字段5’, `param6` varchar(64) DEFAULT NULL COMMENT ’預留字段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=’用戶簽到歷史表’;
