系统说明
校园闲置商品交易系统是根据各高校闲置商品的具体情况和数字化的要求而开发设计的。其总体目标非常明确,即通过高校闲置商品互联网交易平台的建立,将原本指定按时摆档的闲置商品线下促销交易规则转化为基于在线平台的在线交易方式,使校园内的闲置商品交易更加方便、快捷、安全、规范、有针对性。
系统功能需求一般分为用户应用功能和系统管理方法功能。其中,用户应用功能包括用户访问项目、用户登录、用户注册申请、用户检索项目、用户发布项目、用户查询私人信息等。系统管理方式功能包括管理员管理方式项目分类、管理员管理方式项目、,管理员管理方式订单信息管理员管理方式、用户等功能。
根据上述功能需求分析报告,根据用例图描述系统的关键功能。构建测试用例实体模型的第一步是明确实体模型中的用户,用户的标准是:哪个系统维护者,哪个系统参与者,等等。维护者在系统内部,对系统有一定的决策权,而参与者通常位于系统外部和系统操纵之外。
现在很明显,系统的测试用例有三个实体模型,即访问者、注册用户和系统管理员。下面介绍这三个角色的功能:
1 游客
游客是未注册的用户。他们可以浏览和搜索项目。如果他们需要物品,他们必须首先注册为网站用户。游客的主要功能如下(图3-1为游客用例图):
浏览物品搜索物品注册成为网站用户图3-1游客用例图
注册用户注册用户是经过合法认证的网站用户。登录网站后,他们可以浏览文章、搜索文章、发布文章、跟踪文章、文章和查看个人中心。注册用户的主要功能如下(图3-2为注册用户用例图):
图3-2 注册用户用例图
系统管理员系统管理员主要负责系统的后台管理,主要功能如下(图3-3为系统管理员用例图):
图3-3 系统管理员用例图
在确定系统用户和用户功能后,我们可以构建校园闲置商品交易系统的用例图。整个系统的用例图如图3-4所示:
图3-4 系统总体用例图
环境需要1.运行环境:最好是java jdk 1.8,我们在这个平台上运行的。其他版本理论上也可以。2.IDE环境:IDEA,Eclipse,Myeclipse都可以。推荐IDEA;3.tomcat环境:Tomcat 7.x,8.x,9.x版本均可4.硬件环境:windows 7/8/10 1G内存以上;或者 Mac OS;5.数据库:MySql 5.7版本;6.是否Maven项目:否;
技术栈
后端:Spring+SpringMVC+Mybatis前端:JSP+CSS+JavaScript+jQuery使用说明
使用Navicat或者其它工具,在mysql中创建对应名称的数据库,并导入项目的sql文件;使用IDEA/Eclipse/MyEclipse导入项目,Eclipse/MyEclipse导入时,若为maven项目请选择maven;若为maven项目,导入成功后请执行maven clean;maven install命令,然后运行;将项目中springmvc-servlet.xml配置文件中的数据库配置改为自己的配置;运行项目,在浏览器中输入http://localhost:8080/ 登录运行截图

session.setAttribute(Const.CURRENT_USER,response.getData());
