Failed to parse multipart request org.apache.commons.fileupload.FileUploadException: Processing of multipart/form-data request failed. null
提问by profskz
I know the similar questions are already asked, but unfortunately I can't find the good answer to find the solution for this problem. When I try to upload any file (XML/CSV formats accepted only), it works in local, but on the server it doesn't work. I don't have any timeout or read timeout error. Here you can find more details.
我知道已经有人问过类似的问题，但不幸的是我找不到很好的答案来找到这个问题的解决方案。当我尝试上传任何文件（仅接受 XML/CSV 格式）时，它在本地工作，但在服务器上不起作用。我没有任何超时或读取超时错误。在这里您可以找到更多详细信息。
IMPORTANT : I have this error after correction of Hibernate Session's error, in fact I had always Session Close error in log file so I changed my code and now the Sessions will be closed after finishing the task, but I have this new error only in Server and not in LOCAL !!
重要提示：在更正 Hibernate Session 的错误后，我遇到了这个错误，事实上我在日志文件中总是出现 Session Close 错误，所以我更改了我的代码，现在 Sessions 将在完成任务后关闭，但我只有在服务器中有这个新错误而不是在本地！

I'm assuming that you are uploading a big file and it's taking time to upload.
我假设您正在上传一个大文件并且上传需要时间。
I would suggest to add the following to Connectorwith the following:
我建议将以下内容添加到以下Connector内容中：
<!-- A HTTP/1.1 Connector on port 8080 -->
<Connector protocol="HTTP/1.1" port="8080" address="${jboss.bind.address}"
connectionTimeout="60000" redirectPort="8443"
connectionUploadTimeout="36000000" disableUploadTimeout="false" />
(See this related SO Question).
