摘要

目录主要功能模块设计：主要技术：主要功能实现前端：选课平台首页：登录注册管理：选课推荐分类：课程详情信息：我的个人中心：主要功能实现后台：系统主页设计：选课类型管理：选课信息详情管理

夏天到了、小雪来给大家降降温

话不多说、直接进入主题

主要功能模块设计：

登录注册、首页信息浏览、选课分类查看、选课详情查看、评论交流、收藏、浏览量、以及后台数据管理、用户管理、选课类别管理、选课信息详情管理、评论交流和回复管理、以及公告信息管理等

主要技术：

Java、springMVC、mybatis、Mysql、Tomcat、Jquery、layui、javascript、html、CSS、jsp、log4j等一些常见的基本技术。

主要功能实现前端：

选课平台首页：

输入Http://localhost/访问选课推荐交流平台首页、可以查看轮播图以及各类信息、点击进入详情页面

登录注册管理：

选课推荐分类：

点击查看分类课程推荐信息、按照类别查看课程信息、管理员可以在后台添加课程分类信息

以及根据访问量来进行点击排行、

课程详情信息：

课程详情可以查看课程详情信息以及作者信息和浏览量等具体数据、也可以进行评论和收藏等操作

我的个人中心：

包括我的个人信息和收藏夹信息、

主要功能实现后台：

系统主页设计：

主要功能模块有首页的信息统计、选课类型管理、选课详情管理、用户管理、评论和公告管理等数据维护。

选课类型管理：

选课信息详情管理：

列表信息查看添加修改删除以及检索等操作

详情信息

通知公告信息：

数据列表查看和添加修改删除等操作

用户信息管理：

评论交流回复管理：

评论和回复的数据管理

部分关键代码展示：

登录模块：
