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。
