[开发测试]JavaWeb项目 MVC模式 监考管理系统

? ? ? ?本文为JavaWeb项目课程设计，通过利用MVC模式，前端JSP+CSS界面展示，控制器用Servlet完成页面跳转，JavaBean完成数据库类、用户类、教师类等封装，开发出的一款教师监考管理系统。

2.2.1管理员

? ? ?5. 能够实现为每个考场分配合理的考场；

? ? ?6. 能够对每种信息进行单项增加或用excel导入MySql批量式增加；

1. 能够对每种信息进行删除、修改、查询的操作；
2. 能够按照班级考试人数为考试科目合理分配监考教师；
3. 能够单独分配或批量一键分配；
4. 能够一键处理或手动处理教师请求调换信息；
5. 能够对监考教师请求信息和监考信息完成后发送邮件提醒；
6. 具有良好的可视化前端界面和温馨提示；
7. 能够显示当前已有任务的教师总监考次数；

2.2.2 教师

教师同样作为本系统的使用者，能够完成与自身相关的功能，具体功能需求总结如下：

1. 需要输入正确的账号密码登录整个系统；
2. 能够完成密码等个人信息的修改；
3. 能够查看个人当前需监考的考试信息；
4. 能够查看当前所有时间状态等；
5. 对有异议的考试可发送申请调换请求；
6. 友好界面显示，提醒当前待监考场数；
7. 收取邮件提醒监考任务等；
