数据库：Mysql: mysql5.7
应用服务器：Tomcat: tomcat8.5.31
开发工具：IDEA或eclipse
开发技术：SpringBoot+Vue
二，项目简介
相比于传统的体育商品推荐方式，个性化智能的管理方式可以大幅提高体育商品推荐的管理效率，实现了个性化智能体育商品推荐的标准化、制度化、程序化的管理，有效地防止了体育商品推荐的随意管理，提高了信息的处理速度和精确度，能够及时、准确地查询和修正个性化智能体育商品推荐情况等信息。
本课题基于协同过滤算法，主要采用java技术和MySQL数据库技术以及springboot框架进行开发。功能主要包括首页、个人中心、用户管理、商品分类管理、商品信息管理、交流论坛、留言板、系统管理、订单管理等功能，从而实现个性化智能体育商品推荐方式，提高个性化智能体育商品推荐的效率。
近年来，随着互联网科技的进步和发展，人们的生活水平得到了极大的提高，图书的数量也在快速增加，以至于体育商品推荐的数量不断扩大，管理个性化智能体育商品推荐工作也日渐繁重。由于传统的体育商品推荐方式，人工管理成本高，效率低，还存在图书的数量不明确，与管理人员沟通方面的压力。所以人工管理方式在很大的程度上存在弊端。给人们的生活带来了非常大的不便，导致不能满足现在社会的需求。现如今对个性化智能体育商品推荐的管理成为一个越来越受关注的社会问题，对于能够快速的找到体育商品，也是为了提高体育商品推荐的效率。现在的个性化智能体育商品推荐的管理也是在不段完善。
