 项目编号：BS-XCX-024

一，环境介绍

语言环境：Java:  jdk1.8 

数据库：Mysql: mysql5.7

应用服务器：Tomcat:  tomcat8.5.31

开发工具：IDEA或eclipse+微信开发者工具

开发技术：Springboot+vue+微信小程序

二，项目简介

本项止基于Springboot+vue+微信小程序实现了一个校园二手物品商城交易系统。系统的后台使用springboot+mybatis开发实现，后台管理页面使用Vue+ElementUI开发实现，用户端基于微信小程序开发实现。前端用户使用微信登录小程序后，可以在线浏览二手商品，并在线购买下单和评论等，同时自己也可以发布相应的二手商品，并管理自己的订单信息和销售信息。管理员登录后台管理系统可以管理人员、商品分类、商品、订单等相关信息。具体见下面展示。

三，系统展示

前端小程序

在商品详情里可以和发布人在线发消息交流，在线评论，在线下单交易

商品分类查询

发布二手商品

在线信息交流

个人中心：可以管理自己发布的商品，查看自己的收藏记录，查看自己的订单，查看己销售的订单，查看评论和消息回复等。

后台管理

分类管理

商品管理

其它略
