项目介绍
该超市订单管理毕业设计基于jdk8版本开发，在部署时需要使用jdk8以上的版本。使用了目前流行的框架组合springboot+mybatis的框架技术， 实现了供应商管理对供应商实现增删改查、订单管理对超市订单实现增删改查、用户管理等功能，适用于小型超市的使用，通过学习该超市订单管理的毕业设计，对于springboot+mybatis框架的组合能够有更深层次的理解。
由于本程序规模不大，可供课程设计，毕业设计学习演示之用
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.数据库：MySql 5.7版本；
6.是否Maven项目: 是
技术栈
1. 后端：springboot MyBatis
2. 前端：JSP+css+javascript
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application.yml配置文件中的数据库配置改为自己的配置;
4. 运行成功后，访问http://localhost:8080/ 到登录页面
