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
