项目编号：BS-XX-136

一，项目简介

   这是一个前后端分离的电影管理和推荐系统，采用Vue.js + Spring Boot技术栈开发，电影数据来源于豆瓣，采用Python爬虫进行爬取相关电影的数据，将数据插入mysql数据库，然后在前端进行数据展示。后台主要进行电影相关基本数据的管理功能。给用户推荐的电影数据写入到REDIS数据库中进行存储。推荐算法采用协同过滤算法，采用于ItemCF和UserCF相结合的方式来进行推荐。

二，环境介绍

语言环境：Java:  jdk1.8

数据库：Mysql: mysql5.7+Redis

应用服务器：Tomcat:  tomcat8.5.31

开发工具：IDEA或eclipse

前端技术栈：

- Vue.js

- ElementUI

- axios

后端技术栈：

- Spring Boot

- MyBatis

- Apache Shiro

- Spring Data Redis

五，项目总结

   项目采用前后端分离的方式来进行开发实现，并进行了数据的爬取操作，相关亮点比较多，业务功能相对较少。主要实现数据的爬取及展示以及相关的推荐功能。
