随着社会的不断发展会和人口数量的不断增加，阅读需求也逐渐增大，这意味着我们需要越来越多的书籍来阅读。众所周知，就书本的来源上说，制造大量的书本就意味这需要大量的纸浆，砍伐大量的树木会破坏地方的原本生态环境，生产纸张的过程中也会产生污水，影响水质污染河流。因此，为了减少环境破坏，同时也有充分的书籍可以阅读，书籍的循环利用是一项必不可少的措施。在不断发展的今天，计算机网络的发展非常迅速，网络覆盖范围不断矿大，网络消费已经非常普及，这给二手书的循环利用带来了机遇。<br>二手书网络平台使得书籍的循环利用得到了不少的提升，消费者们可以以较小的代价买到自己需要的书籍，减轻了消费者的经济负担，同时也使得书籍本身的价值得到了最大化，间接地保护了生态环境。本二手书交易是针对校园内部学生的二手书交易进行设计的，目的在于循环使用书籍，减少环境破坏，同时需求者可以更好地取得自己需要的书籍，有暂时不需要的书籍，卖家可以向此系统发布书籍，有需要书籍的买家可以通过本系统购买物美价廉的书籍。<br>本文的二手书网络平台设计为B/S结构，基于SSM框架技术，使用JAVA语言开发，其中使用的数据库时是MYSQL。<br>此系统共实现了 7个功能模块：查询书籍功能，联系商家功能，管理心愿书单功能，书籍管理功能，管理个人信息功能，查看交易记录功能，查看帮助。<br>关键词：B/S结构；JAVA;二手书网络平台
