结合以前一个项目，将普通的jdbc进行了相关整合，全部改写成了hibernate接口

 

项目名称：短视频分享平台

主要功能：用户模块：注册、登录、编辑资料、查看用户相关

分类模块：分类添加、查看

视频共享模块：查看、上传、删除

点赞模块：是否已赞、点赞

评论模块：评论、查看

关注模块：关注、查看关注列表、是否已关注、取消关注

 

实体类：

用户 User

分类 Find

视频信息 Video

点赞信息 Praise

评论信息 Post

关注信息 Follow

 

对应关系：  一个用户对应多个视频，对应多条评论，对应多个点赞信息，对应多个关注信息。

                    一个分类对应多个视频

                   一个视频对应一个分类，对应一个用户，对应多个点赞信息，对应多个评论信息

　　　　　 一个赞对应一个用户，对应一个视频

                   一条评论对应一个用户，对应一个视频

                   一个关注对应一个用户
