最近帮小伙伴做了个基于SpringBoot和协同过滤算法的体育商城系统。
一，SpingBoot介绍
现如今后台开源框架主流的有SSH、SSM、SpringBoot，但是SSH、SSM框架的环境配置项较多，而SpringBoot主要的设计思想就是约定大于配置，故而SpingBoot在设计时几乎达到零配置。SpringBoot整合了业界上的开源框架。具体采用技术框架描述如下：
（1）Mybatis：Mybatis：提供自动映射，动态SQL，级联，缓存，注解，代码和SQL分离等特性，使用方便，同时也对SQL进行优化。
（2）SpringMVC：通过一套MVC注解，让POJO成为处理请求的控制器，无需实现任何接口，同时，SpringMVC还支持REST风格的URL请求。
（3）SpringBoot：从本质上来说，Spring Boot就是Spring,它做了那些没有它你也会去做的Spring Bean配置。
SpringBoot是一款非常强大后台框架，因为SpringBoot开发时可以基本不用写配置文件，所以使用SpringBoot搭建网站的后台环境，在SpringBoot的yml配置文件中写入项目启动端口，项目就可以启动。项目的Java文件还有静态文件都是由SpringBoot来管理。
二，协同过滤算法介绍
协同过滤算法常用于推荐，根据用户的喜好或者兴趣进行推荐。是基于邻域的方法，而这种方法主要有两种算法：基于用户的协同过滤算法（给用户推荐和他兴趣相似的其他用户喜欢的产品）和基于物品的协同过滤算法（给用户推荐和他之前喜欢的物品相似的物品）。
三，系统功能需求
