Upload File issue with spring 3 - MultipartException , connection reset

Question

I got a form belonging to a web app that contains a "file" field to upload a pdf file.( spring 3 environment, multipart file upload) Uploading file works fine in test environnement (all browsers), and only works with Firefox in production environment (file upload cause connection reset exception with low internet connection client browser especially)

The following exception is thrown a few seconds after submit button is pressed : ( browser is IE/Chrome running in windows environment but not Firefox)

org.springframework.web.multipart.MultipartException: Could not parse multipart servlet request; nested exception is org.apache.commons.fileupload.FileUploadBase$IOFileUploadException: Processing of multipart/form-data request failed. null

这种例外的可能原因是什么？
文件上传时的连接重置通常意味着客户端中止发送...那么什么？任何帮助将不胜感激.克里斯托夫D.

Answer 1

您可以捕获客户端和服务器之间的 tcpdump 并查看谁正在重置连接。我们的应用程序中也遇到了类似的问题，这是防火墙断开了连接。apache [LimitRequestBody] 中还有另一个设置，它会在文件上传达到该限制后中止上传。在这两种情况下，来自 apache 和 mod-jk 的日志在这些场景中调试起来不太清楚。
