【Spring Boot+Kafka+Mysql+HBase】实现分布式优惠券后台应用系统（附源码）

需要全部代码请点赞关注收藏后评论区留言私信~~~

一、系统简介

分布式优惠券后台应用系统服务于两类用户群体，一类是商户，商户可以根据自己的实际情况即进行优惠券投放，另一类是平台消费用户，用户可以去领取商户发放的优惠券

二、整体架构

分布式优惠券后台应用系统采用SpringBoot作为主体开发框架，使用Kafka消息队列实现优惠券从商户到用户的传递，Mysql存储商户信息，HBase存储用户信息，优惠券信息等，Redis保存优惠券的缓存信息 系统整体架构如下

对于商户投放子系统，商户注册生成对应的商户实体信息，并保存到Mysql数据库，商户可以投放自己商家的优惠券，且优惠券有自己的Token存放于Redis中，投放的优惠券信息将由Kafka向用户消费子系统发送，而商户投放的优惠券并不在Mysql中进行存储，而是在商户投放子系统中放送消息给Kafka，用户消费子系统通过侦听Kafka消息获得Kafka分布式信息并存储到HBase中，用户通过读取Redis中的优惠券信息领取消费券，并将自己领取到的优惠券信息存放在HBase中

三、表结构设计

mysql表结果设计如何 存放商户基本信息

HBase表结构设计

在HBase中建立三个表，分别是消费用户表，优惠券表和优惠券领取表

四、系统实现

1：新建MAVEN工程 引入相关依赖包

2：修改applicaiton.yml文件 包括mysql和kafka的连接相关配置

3：建立各个类包存放路径

4：核心代码实现

五、效果展示

商户投放子系统成功启动效果如下

用户子系统成功启动效果如下

发放优惠券界面如下

数据库表插入情况如下
