摘要

跳蚤市场的物品一般都是闲置物品，学生往往能够以较低的价格买到自己需要或者喜欢的东西，但是跳蚤市场不肯能每天都在学校内举行，所以利用网上跳蚤市场可以让学生无时间无空间无地点的限制进行选购，能够丰富课余的时间。本课题目的在于解决当下因疫情防控需要大部分高校采取封闭式管理，学生外出受限，通过网上跳蚤市场实现物品的校内流通，满足学生的学习生活必需，同时对于毕业年级来说，带不走的或者无用的闲置物品都可以通过设计并开发的高校网上跳蚤市场进行交易，使大量的闲置物品得到充分的利用。

本次设计按照软件工程开发规范进行课题的设计、实现、测试和部署发布，编写对应的设计和测试文档、创建高校网上跳蚤市场的运行环境， Spring、Springboot、MyBatis作为项目开发的三驾马车，是 B/S 开发的黄金组合，易于上手，易于开发、调试和维护。利用Spring-Springboot-MyBatis技术完成高校网上跳蚤市场所需的数据库创建和源代码编写。

Abstract

Flea market items are generally idle items, students are often able to buy what they need or like at a lower price, but flea markets can not be held in school every day. So the use of online flea market can make students have no time, no space and no place to buy, can enrich the spare time. The purpose of this project is to solve the problem that most colleges and universities adopt closed management, students are limited to go out, realize the circulation of goods through the online flea market, and meet the needs of students' study and life.

This design carries on the project design, the realization, the test and the deployment release according to the software engineering development specification, compiles the corresponding design and the test document, creates the university online flea market operation environment, Spring、Springboot、MyBatis as the project development troika, is the B/S development gold combination, easy to use, easy to develop, debug and maintain. Spring-Springboot-MyBatis technology is used to complete the database creation and source code of the online flea market in colleges and universities.
