Linux下运行start.sh报错：
Error response from daemon: Container ba37672916ddb50694ab7a168881c0454d96da482480a4bf9f48c875f57147a7 is not running

1. PathTravel

The current implementation of the file upload functionality lacks proper filtering and validation of the uploaded file names. This allows attackers to upload files with malicious names that can potentially traverse to arbitrary paths on the server. By exploiting this vulnerability, an attacker can upload files to unintended directories, potentially compromising the system's integrity and confidentiality.

It is necessary to implement robust checks on the file name obtained from file.getOriginalFilename() to ensure it does not contain any path traversal sequences like "..". Additionally, validate the final path to ensure it falls within the intended directory specified by the "dir" parameter.

2. Duplicate File Uploads

The current implementation of the file upload feature does not include a file renaming mechanism. This poses a risk as it allows for the overwriting of existing files with the same name. This functionality gap can be exploited by attackers to maliciously overwrite files belonging to other users, leading to data loss or unauthorized access to sensitive information.

bug太多，

1. 无故404；表单异常退出
2. api接口访问后无法持续保留
3. exam接口详情无法打开
4. 功能不齐全，增加相关的内容还需要 alter/update/delete 数据库操作；功能不完善。

请问下，项目功能简介下有管理用户功能的，但测试时登入管理员界面，发现缺少了管理用户的模块功能。

按照文档里的指示，前端build总是失败，貌似有多个版本冲突，比较难搞，能不能直接搞个dockerfile？
这个dockerfile最好是包含构建前端，后端和运行的。谢谢

在考试管理详情中，觉得应该可以加一个teacher角色对于学生角色的成绩管理，方便后期统计

create_time 是自动插入的，怎么会空？求翻！

有支持简答题的计划不？

npm run serve各种问题 解决了十来个 还是报错 放弃了

项目跑起来之后，有两个模块没有数据，发现是vue这个list插件出了问题，请问该怎么解决？

这个情况怎么解决啊

    进行解析包的时候，出现以上错误，配置文件不知道从哪里开始配置，请求解答，感激不尽。救救孩子小白叭

请问，批量导入题目和选项上支持图片可以做吗？

移动端不显示交卷按钮，只可以切换到电脑版才可见交卷按钮

为什么我在运行npm run serve的时候报错

1.开始考试之后，页面中的倒计时似乎没有反应，是不是应该有一个显示的时间进行倒计时，时间到了自动提交呢？
2.批量导入题库这一块怎么设计呢？

后端代码没有发现DataSourceConfig 文件，能否指点一下如何配置多数据源

根据学生错题情况展开针对性加强教育。

vue和后端的配置端口都是8000 但是后端报错无法代理到'localhost:9527'这种情况该怎么解决呀？

请问在spring-boot-online-exam/backend/exam/src/main/resources/application.yml中是没有password的选项的，只有后面application-dev和application-prod有而且密码不一样，希望能重新更新一下安装配置教程，新手真的好难看懂，谢谢，辛苦了

不同身份的用户切换登录时，存在跳转到404页面的情况
比如教师先登录，然后切换到“考试管理”这一栏，再退出登录，再以学生身份登录，则会跳转到404.
根据我个人的分析，在代码中你应该有专门的逻辑对用户当前访问的路由进行记录，并且重新登录时会跳转到那个路由。但不同身份的用户的路由权限不同，所以造成无法访问从而落到404的情况。
我觉得每次重新登录跳转到首页就可以了，因此可以在退出登录的时候将当前访问的路由置为“/home”，就能避免这种bug。

由于代码比较复杂，我不知道记录当前访问的路由是不是下面这个selectedKeys(在component/Menu/menu.js文件下)

data () { return { openKeys: [], selectedKeys: [],//是这个吗？ cachedOpenKeys: [] } },

仅个人建议，仅供参考
