Java阶段项目展示 -- 电影购票系统

步骤一、

集成日志框架、用于后期记录日志信息；
定义一个电影类，Movie类包含：片名、主演、评分、时长、票价、余票；
系统包含2种角色类型：商家、客户，存在大量相同属性信息；
定义User类作为父类，属性：登录名称、密码、真实名称、性别、电话、账户金额；
定义Business类代表客户角色，继承User类，独有属性：店铺名称、地址；
定义Customer类代表客户角色，继承User类，独有属性：暂无；
定义集合List<User>用户存放系统注册的用户对象信息；
定义集合Map<Business,List<Movie>>存放商家和其拍片信息。

步骤二、

首页需要包含登录，商家入驻，客户注册功能；
商家和客户可以共用一个登录功能；
判断登录成功的用户的真实类型，根据用户类型完成对应的操作界面设计；

步骤三、【商家功能--展示详情、影片下架、退出】

展示本商家的信息和其拍片情况；
提供影片上架功能：就是创建一个影片对象，存入到商家的集合中去；
退出：回到登录的首页

步骤四、【影片修改、影片下架】

影片修改功能：拿到需要修改的影片对象，修改里边的数据后重新将改影片上架；
影片下架功能：从商家集合中移除改影片对象

步骤五、【展示全部影片信息、用户购票功能】

其实就是遍历全部商家和其拍片信息并展示出来；
用户可以选择需要购买票的商家和其电影信息；
选择购买数量，购买成功后需要支付金额，并更新商家金额和客户金额
