项目介绍
基于JSP+Servlet的网上订餐管理系统的设计与实现。该项目为前后台管理项目。
前台主要展示给普通用户，主要功能有菜品分类、最新菜品、销售排行、美食预订、营养小贴士、餐点搜索、订餐车、
在线留言等；
后台主要提供给管理员，主要功能有菜品管理、菜品类别管理、营养小贴士管理、会员管理、员工管理、留言管理、采购管理、销售订单查询、统计管理、用户管理等；
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：Servlet
2. 前端：JSP+bootstrap+jQuery
使用说明
1. 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，下载所需jar包；
2. 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；
3. 将项目中DBConn.java文件中的数据库配置改为自己的配置
4. 配置tomcat，然后运行项目，输入localhost:8080/xxx 登录
5. 后台管理员账户:admin 密码:admin
前台普通用户：111 密码：111
