JavaWeb校园二手交易平台(源码+数据库+文档)
项目描述
本文主要论述了如何使用JAVA语言开发一个高校二手交易平台，本系统将严格按照软件开发流程进行各个阶段的工作，采用B/S架构，面向对象编程思想进行项目开发。在引言中，作者将论述高校二手交易平台的当前背景以及系统开发的目的，后续章节将严格按照软件开发流程，对系统进行各个阶段分析设计。
高校二手交易平台的主要使用者分为管理员和用户，实现功能包括管理员：个人中心、用户管理、商品上架管理、订单信息管理、商品信息管理、联系商家管理、论坛管理、管理员管理、系统管理，用户：个人中心、商品上架管理、订单信息管理、商品信息管理、联系商家管理、我的收藏管理，前台首页；首页、商品信息、论坛信息、新闻资讯、我的、跳转到后台、客服等功能。由于本网站的功能模块设计比较全面，所以使得整个高校二手交易平台信息管理的过程得以实现。
本系统的使用可以实现本高校二手交易平台管理的信息化，可以方便管理员进行更加方便快捷的管理。
