一、项目介绍
在线电影订票系统基于Spring+SpringMVC+Mybatis开发，系统分为前台和后台，前台主要用来用户浏览电影信息，订票，评价等操作，后台主要是用来管理电影，用户等。
前台功能如下：
- 网站公告
- 推荐电影
- 全部电影
- 电影订票
- 电影评价
- 我的订单
- 购物车
- 个人中心，
后台功能如下：
- 管理员信息
- 网站用户信息
- 新闻公告信息
- 电影类型信息
- 城市信息
- 影院信息
- 电影信息
- 订单信息
- 电影评价信息等功能
二、技术框架
- 后端：Spring，Springmvc，Mybatis
- 前端：jquery，bootstrap
三、安装教程
- 用idea打开项目
- 在idea中配置jdk环境
- 配置tomcat8.0
- 新建数据库，导入数据库文件
- 在springmvc-servlet.xml文件中将数据库账号密码改成自己本地的
- 启动运行, 后台管理员账号密码 admin/123456，前台用户账号密码 xiaoli/123456
