仿哔哩哔哩微信小程序（基于SSM的仿哔哩哔哩系统）
众所周知哔哩哔哩是大家喜爱的视频网站，网站的样式和内容都是非常不错的。今天就跟大家分享一个基于SSM框架的仿哔哩哔哩的系统，当然没法跟原网站比，这是简单的实现用户上传视频、观看视频、搜索视频、发送评论、发送弹幕等简单功能。

什么是SSM框架
Spring
Spring就像是整个项目中装配bean的大工厂，在配置文件中可以指定使用特定的参数去调用实体类的构造方法来实例化对象。也可以称之为项目中的粘合剂。
Spring的核心思想是IoC（控制反转），即不再需要程序员去显式地`new`一个对象，而是让Spring框架帮你来完成这一切。
SpringMVC
SpringMVC在项目中拦截用户请求，它的核心Servlet即DispatcherServlet承担中介或是前台这样的职责，将用户请求通过HandlerMapping去匹配Controller，Controller就是具体对应请求所执行的操作。SpringMVC相当于SSH框架中struts。
mybatis
mybatis是对jdbc的封装，它让数据库底层操作变得透明。mybatis的操作都是围绕一个sqlSessionFactory实例展开的。mybatis通过配置文件关联到各实体类的Mapper文件，Mapper文件中配置了每个类对数据库所需进行的sql语句映射。在每次与数据库交互时，通过sqlSessionFactory拿到一个sqlSession，再执行sql命令。
