1) 设计一个用户登录页面、一个用户登录信息验证页面、一个用户登录成功页面、一个错误处理页面、两个受保护页面以及若干被静态包含的页面片段。
2) 用户登录信息包括学号和密码，学号是本人学号并且密码正确则登录成功，自动跳转到用户登录成功页面；如果出现异常（例如学号没有输入、密码没有输入、学号或密码不正确等），则抛出异常，由错误处理页面处理。
3) 登录成功页面，显示登录用户信息，并显示受保护页面访问的列表。
4) 一个受保护页面介绍本人的简历；一个受保护页面介绍本人的业余爱好。两个页面必须登录后访问，如果没有登录，则跳转到登录页面。
5) 静态包含的页面片段包括三个：一个是统一的头部信息；一个是统一的尾部信息；一个是验证用户是否登录的代码。
