基于Java+SpringBoot+Mybatis+Vue+ElementUi的校园闲置物品交易

项目介绍

我们通过java语言，后端springboot框架，数据库mysql，前端vue技术，开发本系统，校园闲置物品交易网站系统中的功能模块主要是实现管理员；首页、个人中心、用户管理、商品类型管理、商品信息管理、系统管理、订单管理，用户：首页、个人中心、商品信息管理、我的收藏管理、订单管理。前台首页：首页、商品信息、商品资讯、个人中心、后台管理、购物车等功能。经过认真细致的研究，精心准备和规划，最后测试成功，系统可以正常使用。分析功能调整与校园闲置物品交易网站实现的实际需求相结合，讨论了Java语言开发校园闲置物品交易网站的使用。

开发环境

开发语言：Java
数据库 ：MySQL
系统架构：B/S
