高校手机签到系统——第一部分Authority权限系统（上）

　　序：今天开始写一个算是我第一个系列的文章——高校手机签到系统。本系统结合我们学校自身的一些特点编写。这是我的毕业设计项目，写在这里算是给最后论文的时候一些点滴的记录。另外也想通过这个系列的文章找到一份工作，我知道许多大神都在博客园。我的邮箱：dugukuangshao@Gmail.com，在这个系列文章快完成的时候，我会将该项目开源并附上简历。

基本思路：根据每堂课唯一的guid标识加上当前时间，生成每5秒刷新一次的图片，再用手机客户端连接到校园网wifi再去扫描这张图片来签到。手机客户端还能从校园网上获得课程表。最后通过签到的数据还能分析课程的到课率、班级出勤率等。

由于教务处网站没有开放的接口，所以我自己实现了一个选课的系统，根据这个系统来查询课程表。选课网站构成了服务器端，采用.net平台，毕业设计自然要有些难度和挑战，所以手机客户端采用了android平台，也就是java。服务器端使用mvc4模式开发，mybatis.net作为orm的框架。

　　第一部分是Authority权限系统。涉及到domain层的Membership和Organization。如图所示：Membership下存在四个类：User用户、Profile详细资料、Role角色、UsersInRoles。Organization下存在三个类：Class班级、Institution机构、UsersInInstitutions。各类之间的关系如图：

代码如下：

UsersInInstitutions.cs

Profile里的IMSI字段是手机的唯一标识，用来绑定学生的客户端，也就是一部手机只能为一个人签到。Profile继承自User，为什么是继承？Profile和User难道不是Has-A的关系，怎么是IS-A？从User的属性看，User只是一个Account，用户在这个网站上的账户。而，Profile具有完整的一个Person的属性，所以谁属于谁还不好说。这里采用继承，是因为我在查询User的sql语句中采用了联合查询，User和Profile一起返回，在Dao层的方法里使用了泛型，sqlMapper即可根据需要返回我要的User或者Profile。这样做在性能上有多大的影响我也不是太清楚，只是图省事儿，学校的学生老师也不是太多。下面是Mapper的代码：
