系统背景 :

中国进入新时代新征程，人们对精神生活的需求越来越多。鲜花作为新时代青年大学生节日赠送的首要选择，其市场需求也逐年扩大。传统花店或企业的经营模式中，需要投入大量人工、物力且覆盖面小、客户量低、利润来源固化，整个鲜花的销售处于手工或者半手工的状态，效率低下、可靠性低下。随着花店或企业的业务规模的不断扩大，传统的交易模式问题越来越严重。

创新点：

1．使用Echarts对鲜花销量、销售金额进行图形化展示，方便管理员查看。

2．智能推荐：根据用户以往的订单记录来为用户推荐相似的鲜花。

主要功能 ：

本系统的主要功能分为用户管理、购物车管理、鲜花管理、分类管理、订单管理五大模块

开发平台及使用技术 ：

系统：Window10 开发语言：Java 数据库：Mysql 开发工具：IDEA

使用技术：

Spring Boot+Mybatis+HTML+CSS+JavaScript+Thymeleaf
