上传文件到OSS报错：

[Server]Unable to execute HTTP request: Position is not equal to file length

控制台报类似以下的错：

[ErrorCode]: PositionNotEqualToLength
[RequestId]: 603D07EA9ACC07383080C699
[HostId]: naiyi-course.oss-cn-shenzhen.aliyuncs.com
[ResponseError]:

  <Message>Position is not equal to file length</Message>

  <HostId>xxx-xxxx.oss-cn-shenzhen.aliyuncs.com</HostId>
</Error>

27:40.004 ERROR o.a.c.c.C.[.[.[.[dispatcherServlet]:175  Servlet.service() for servlet [dispatcherServlet] in context with path [/file] threw exception [Request processing failed; nested exception is com.aliyun.oss.OSSException: Position is not equal to file length

说明：

其实报错很明显，我的代码未加判断，分片上传文件功能代码不够严谨。

解决：

将OSS上的文件，先删掉，再重新执行即可。
