这个项目涉及到Shiro整合JWT、秒杀功能所具备的基本要求(限流、乐观锁、接口隐藏、JMeter高并发测试等等)、消息中间件RabbitMQ的异步邮件通知和死信队列、沙箱支付宝模拟支付等等技术亮点。
项目功能：该项目分为买家、卖家、管理员三个角色。买家角色的功能：登录、注册、浏览图书、管理购物车、结算订单、支付订单、查看订单、修改个人信息等等功能。
卖家角色的功能：登录、注册、浏览商品、管理自己发布的图书、管理收到的订单、查看自己的收益详情等等。管理员角色的功能：登录、管理所有用户信息、管理权限信息、管理所有卖家发布的图书、管理所有订单信息、管理所有支付信息、查看总共收益详情等等。
应用技术：SSM + Jsp + MySQL + Redis + JWT + Shiro + RabbitMQ + EasyUI + 沙箱支付宝 + 令牌桶限流 + 乐观锁等等
运行环境：Eclipse/IntelliJ IDEA + MySQL5.7 + Maven3.6.3+ JDK1.8 + Redis5.0.5+ Tomcat8.5 + RabbitMQ3.7.7
