团队作业（五）：冲刺总结（六）

1.今日任务安排

• 继续完成后端*.Controller代码的编写
• 建立数据库链接，对数据库的响应（数据库表的增、删、改、查）。
• 完成访问控制功能的实现（管理员、审核员、普通工作人员等）。
• 继续前端界面的设计

2.遇到的困难

1.在实现公文的提交和审核功能的时候，普通工作人员可以成功提交文件，但当审核员从系统中要审核提交者的文件的时候，下载时公文显示的是乱码。

文件上传以后，加密过程是成功的，但是下载解密后的文件显示乱码，问题出在解密的传输流问题，将代码修改后成功解决该问题。

2.在撰写公文时，标题不宜写的过于冗长，否则将会出现系统警告。

3.今日成果
