• Java项目：ssm超市订单管理

    作者主页：夜未央5788

     简介：Java领域优质创作者、Java项目、学习资料、技术互助

    文末获取源码

    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spring+springMVC+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SSM框架的组合能够有更深层次的理解。

    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：JSP+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.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. 运行成功后，访问http://localhost:8080/supermarket/login.htm到登录页面
