基于minio做的分片上传文件
支持秒传、断点续传



 * 流程  init -> chunkUpload -> complete
 *
 * 已上传过的文件秒传（文件的md5编码   是一样的表示同一个文件）
 *
 * 24小时内可以断点续传（生成的chunkUpload有效期是24小时，redis中 MULTIPART_UPLOADID_KEY和MULTIPART_UPLOADID_CHUNK_KEY有效期是24小时）
 * 超过24小时均失效
 *
 * 所有的chunkUpload调用成功后，调用complete； chunkUpload未都调用成功时调用complete会返回500
 
 
工具：
* 多个分片url请求参考：com.example.miniomultipartupload.common.util.PostUtils
* 切割文件参考：com.example.miniomultipartupload.common.util.SplitMergeFileUtil

请求示例：细节参考MultipartController类
* 1、分片上传初始化
* http://localhost:8080/multipart/init
* 请求体：{
*    "filename": "aaa123.mp4",
*    "size": 48329356
* }
* 返回值：{
* 	"msg": "操作成功",
* 	"code": 200,
* 	"data": {
* 		"uploadId": "936f4244-84d3-4d6c-8cff-cce0907bd823",
* 		"uploadUrlList": [
* 			"/multipart/chunkUpload?uploadId=936f4244-84d3-4d6c-8cff-cce0907bd823&chunk=chunk_0",
* 			"/multipart/chunkUpload?uploadId=936f4244-84d3-4d6c-8cff-cce0907bd823&chunk=chunk_1",
* 			"/multipart/chunkUpload?uploadId=936f4244-84d3-4d6c-8cff-cce0907bd823&chunk=chunk_2",
* 			"/multipart/chunkUpload?uploadId=936f4244-84d3-4d6c-8cff-cce0907bd823&chunk=chunk_3",
* 			"/multipart/chunkUpload?uploadId=936f4244-84d3-4d6c-8cff-cce0907bd823&chunk=chunk_4"
* 		],
* 		"partCount": 5,
* 		"url": null
* 	}
* }

* 2、调用分片接口
* http://localhost:8080/multipart/chunkUpload?uploadId=936f4244-84d3-4d6c-8cff-cce0907bd823&chunk=chunk_0,
* http://localhost:8080/multipart/chunkUpload?uploadId=936f4244-84d3-4d6c-8cff-cce0907bd823&chunk=chunk_1,
* http://localhost:8080/multipart/chunkUpload?uploadId=936f4244-84d3-4d6c-8cff-cce0907bd823&chunk=chunk_2,
* http://localhost:8080/multipart/chunkUpload?uploadId=936f4244-84d3-4d6c-8cff-cce0907bd823&chunk=chunk_3,
* http://localhost:8080/multipart/chunkUpload?uploadId=936f4244-84d3-4d6c-8cff-cce0907bd823&chunk=chunk_4

* 3、合并分片
* http://localhost:8080/multipart/complete
* 请求体：{
*     "uploadId": "936f4244-84d3-4d6c-8cff-cce0907bd823"
*  }
* 返回值：{
*     	"msg": "2023/02/10/91fc7d51-6caf-4d66-834e-165456f55975_20230210121947A001.mp4",
*     	"code": 200
*     }
