Java项目:校园二手交易平台(java+SSM+Thymeleaf+Html+jQuery+mysql)

源码获取：博客首页 "资源" 里下载！

项目介绍

本次设计的是一个校园二手交易平台（C2C），C2C指个人与个人之间的电子商务，买家可以查看所有卖家发布的商品，并且根据分类进行商品过滤，也可以根据站内搜索引擎进行商品的查询，并且与卖家联系，达成交易的意向，也可以发布求购的信息，让卖家查看之后，与之联系，进行交易。而此次主要是针对校园用户所设计的网站，对于数据的分类应该更多的考虑校园用户的需求，例如二手书籍、二手数码等的分类应该更加细致。由于是C2C的项目，因此本项目无需后台管理。

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.是否Maven项目: 是；查看源码目录中是否包含pom.xml；若包含，则为maven项目，否则为非maven项目
6.数据库：MySql 5.7版本；

技术栈

1. 后端：Spring SpringMVC MyBatis
2. 前端：Thymeleaf+Html+jQuery

使用说明

1. 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；
2. 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，配置tomcat，然后运行；
3. 将项目中jdbc.properties配置文件中的数据库配置改为自己的配置;
4. 运行项目，输入localhost:8080/xxx 登录
