文末获取源码

一、相关文档

        系统中的核心用户是系统管理员，管理员登录后，通过管理员菜单来管理后台系统。主要功能有：个人中心、用户管理、食堂管理、食堂菜单管理、菜系分类管理、消息留言管理、留言板管理、系统管理、订单管理等功能。

        用户进入系统可以进行个人中心、消息留言管理、我的收藏管理、订单管理等。

二、项目介绍

角色：管理员、用户

前台用户可以实现商品浏览，加入购物车，加入收藏，预定，选座，个人信息管理，收货信息管理，收藏管理，评论功能，我的订单等。
食堂：个人中心、修改密码、个人信息、食堂菜单管理、菜系分类管理、消息留言管理、订单管理
系统管理员，管理员登录后，通过管理员菜单来管理后台系统。主要功能有：个人中心、用户管理、食堂管理、食堂菜单管理、菜系分类管理、消息留言管理、留言板管理、系统管理、订单管理等功能。
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

三、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 5.7/8.0等版本均可；

四、技术栈

后端：SSM(Spring+SpringMVC+Mybatis)
前端：JSP+CSS+JS+JQUERY+Layui

五、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，修改配置，运行项目；
3. 将项目中db.xml配置文件中的数据库配置改为自己的配置，然后运行；
前台：http://localhost:8080/jspmjy54g/front/index.jsp

后台：http://localhost:8080/jspmjy54g/jsp/login.jsp
