Java项目:超市订单管理系统(java+SSM+JSP+bootstrap+mysql)

源码获取：博客首页 "资源" 里下载！

项目介绍

超市订单管理系统。主要功能包括订单管理、供应商管理、用户管理等功能；

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: 否；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：JSP+bootstrap+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. 将项目中applicationContext-jdbc.xml配置文件中的数据库配置改为自己的配置
3. 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；
4. 运行项目，输入localhost:8080/ssm8/login 登录;其中ss8为项目名称，可自定义，但后面路径必须为/login;
