Java项目:校园二手市场系统(java+SSM+mysql+maven+tomcat)

源码获取：博客首页 "资源" 里下载！

一、项目简述（ +IW文档）

功能：本系统分用户前台和管理员后台。 本系统用例模型有三种，分别是游客、注册用户和系统管 理员。下面分别对这三个角色的功能进行描述： 1） 诞 游客是未注册的用户，他们可以浏览物物品，可以搜索物 品，如需购买物品，必须先注册成为网站用户。游客主要 功触吓： a.浏览物品 b.搜索物品 c.注册成为网站用户 2） 注册用户 注册用户是经过网站合法认证的用户，登录网站后可以浏 览物品、搜索物品、发布物品、关注物品、购买物品和查 看个人中心。 3） 系统管理员 系统管理员主要负责系统的后台管理工作，主要功能如 下： 用户管理，商品管理等等。

二、项目运行

环境配置： Jdk1.8 + Tomcat8.5 + mysql + Eclispe （ IntelliJ IDEA,Eclispe,MyEclispe,Sts 都支持）

项目技术： JSP +Spring + SpringMVC + MyBatis + html+ css + JavaScript + JQuery + Ajax + layui+ maven等等。
