摘 要
社会和科技的不断进步带来更便利的生活，计算机技术也越来越平民化。二十
一世纪是数据时代，各种信息经过统计分析都可以得到想要的结果，所以也可以更
好的为人们工作、生活服务。二手物品是学校里最常见的物品，把二手物品再次销
售不仅可以节约资源也可以降低经济消费。如果可以把计算机技术和二手商品销售
相结合更符合现代、用户的要求，实现更为方便的购买商品的方式。
本校园二手交易平台采用 Java 语言和 Vue 技术，框架采用 SSM，搭配 Mysql 数
据库，运行在 Idea 里。本系统针对校园二手商品的交易而开发，提供管理员、用户、
商家三种角色的服务。总的功能包括商品的查询、商品的购买、购物车管理和订单
管理。本系统可以帮助管理员审核商品信息和管理用户（商家、普通用户）信息，
帮助用户实现在线的购买方式，并可以实现订单管理。商家可以发布商品和管理销
售订单等。本系统采用成熟技术开发可以完成网上校园二手交易管理的相关工作。

Abstract
The continuous progress of society and science and technology has brought more
convenient life, and computer technology is becoming more and more civilian. The 21st
century is the data age. All kinds of information can get the desired results through
statistical analysis, so it can also better serve people's work and life. Second hand goods
are the most common goods in schools. Selling second-hand goods again can not only
save resources, but also reduce economic consumption. If we can combine computer
technology with the sale of second-hand goods, it will more meet the requirements of
modern and users, and realize a more convenient way to buy goods.
The second-hand trading platform of the campus adopts Java language and Vue
technology. The framework adopts SSM and MySQL database, which runs in idea. The
system is developed for the transaction of second-hand goods on campus, and provides
services in three roles: administrator, user and merchant. The general functions include
commodity query, commodity purchase, shopping cart management and order
management. This system can help the administrator review the commodity information
and manage the user (merchant, ordinary user) information, help the user realize the
online purchase mode, and can realize the order management. Merchants can release
goods and manage sales orders. The system is developed with mature technology and can
complete the related work of online campus second-hand transaction management.
Keywords: online purchase; Order management; Java language; Mysql database;
