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;
