网上关于minio分片上传的资料不太详细，缺斤少两，所以我基于他们的代码做了一些修改，demo能够正常运行起来，但是偶尔也会发生一些小bug，不过这些都无伤大雅，最终目的是理解代码背后的逻辑和流程

流程：

前端获取生成文件MD5，发送至后台判断是否有该文件缓存，有信息终止上传，无则开始进行文件分片  。这里，我为了简单方便实现便没有使用数据库，直接用redis存储文件信息；前端后端返回的结果进行分片，然后将文件分片的信息传输给后端，后端调用 minio 初始化，返回分片上传地址和 uploadId；前端则根据获取的分片上传地址直接通过axios上传分片文件，不走后端；上传完成后，前端发送请求至后端，后端调用 minio 合并文件；

流程图：

效果图

  1.vue前端

2. minio文件桶

一.前端vue代码（代码较多，我就分开贴）

 项目中使用到的类库：spark-md5、axios、element-ui；

spark-md5 主要用来计算文件MD5，安装命令：

后端使用的是springboot ，使用之前要启动minio，redis，否则文件上传会出现异常。这里我都是使用windows版的
