Java-Project-and-Homework

同济大学2019级信息管理与信息系统专业Java课程作业。本仓库的FinalProject文件夹中为一个使用Spring Boot + Thymeleaf + MyBatis框架实现的一个名为“E-Exercise”的学习答题网站项目,主要包括用户模块、知识模块和习题模块,并将其部署在云服务器上。在知识模块,实现了知识间依赖关系的构建,以Markdown标记语言作为知识模板;在习题模块,实现了习题作答、习题批改、习题推荐等功能,同时在原始Markdown语法的基础上,面向选择题拓展了该标记语言,使得用户能够较方便地添加习题。本网站没有采用XML标记语言作为知识和内容的模板,考虑到的是用户需求,因为不熟悉XML的用户较难使用,因此采用广受大众喜爱的简单易学的Markdown标记语言。本网站可以通过IP地址进行访问,登录界面的URL为http://47.103.73.100:8081/ExerciseOnline/user/toLogin 。在答辩完成后本网站所有源代码将在GitHub上进行开源,遵循MIT License开源协议。
