随着时代的不进步，旧物也成人们的烦恼，许多平台网站都在推广自已的产品像天猫、咸鱼、京东、拼多多。所以开发出一套关于旧物置换网站非常有必要。旧物置换网站主要是借助计算机，通过对用户进行管理。为减少管理员的工作，同时也方便广大用户对个人所需旧物置换的及时查询以及管理。我们通过java语言，后端springboot框架，数据库mysql，前端vue技术开发了本次系统。
该旧物置换网站包括管理员、用户、卖家。其主要功能包括管理员：首页、个人中心、用户管理、卖家管理、旧物类型管理、旧物信息管理、置换交易管理、系统管理等，卖家后台：首页、个人中心、旧物类型管理、旧物信息管理、置换交易管理。前台首页；首页、旧物信息、网站公告、个人中心、后台管理等，用户后台：首页、个人中心、旧物信息管理、置换交易管理等功能。
开发语言：Java
数据库 ：MySQL
系统架构：B/S
后端框架：SpringBoot
前端框架：Vue
开发工具：IDEA或者Eclipse，JDK1.8，Maven
