一、来源：原先的作品来自于大二上同寝室计科同学的期末大作业项目
二、运行环境基于intelij为运行软件，maven做框架依赖，tomacat浏览器展示，mysql数据库

}

三、
主要问题：
1、项目运行过后先进入欢迎界面，在要求更改、添加学生信息的时候才会要求登录。（页面先后顺序不合理）
2、role没有做区分：导致管理员和普通用户利用同一界面
3、用户登录时没有重置密码功能（基本功能欠缺）
4、在查看学生信息时，没有分页功能，如果数据量大会造成美观性不足
5、密码安全性低
创新点：
1、在用户点击重置密码选项的时候，会要求用户输入邮箱号，基于邮箱号把更改密码链接发送给用户，进而用户可以更改密码
2、对用户设置的密码进行了加密处理储存在数据库中，其中数据库中储存着是加密后的密码，而在用户登录的时候还是原先设置的初始密码
更改：
1、调整web.xml配置解决优先界面
2、利用sql语句，增加普通用户和管理员的两种身份，其中index.jsp分配给管理员，新创userDashboard.jsp给于普通用户（只能查看自己信息）
3、增加UpdatePasswordServlet等还有JSP文件，来添加重置密码功能，其中主要利用QQ邮箱地址和我个人邮箱来发送给需要更改密码的用户，并且会创建token来增加“更改密码链接”的安全性
4、简单的分页功能实现，每10个就进行分页
5、创建hashedPassword方法对密码进行加密并记录，用户登录进行解密

注：在把主要问题解决的同时，也对创新点进行了实现，并且把网页跳转的逻辑性进行了调试，并且主要代码在下方可自行查看
四、新代码更改
1、UpdatePasswordServlet

注：其他相关基础代码如login、register等JSP文件不予展示五、重构软件测试截图

六、总结：
1、不熟悉对方的结构花费大量时间去调试梳理
2、引入mail lib库，对库的导入不会，自行在哔哩哔哩上查询查看
3、对自动发送邮箱更改密码方法构建，利用ai且不断调试来完成
改进：
1、代码还有很多的不足问题有待提高例如：用户注册的密码强度的验证性、网页的布局极其美化、还有普通用户信息的完善及其全面性、普通用户的修改自己信息的功能的添加等
