java_fileUpload_demo: 关于文件上传的一些基本介绍（如文件上传、分片上传、md5值秒传、断点续传等）

# java_fileUpload_demo 对应的前端demo页面(vue2)代码，至于怎么搭建前端脚手架和启动vue2框架项目就网上找搭建教程了！

# 本文件上传demo主要演示：
# 单文件、多文件、单文件分片、多文件分片、多文件(md5)分片秒传、单文件分片断点续传等上传方案到项目本地磁盘位置；
# 以及单文件、多文件分片上传至minio文件服务器中的demo；此demo需要在配置文件中将各配置加载项设置为true，加上redis依赖注入

### 需要安装的前端插件
# npm install axios
# npm install element-ui
# npm install spark-md5
