![弹出3上传文件问题]( "弹出3上传文件问题")
本文介绍了弹出3上传文件问题 - MultipartException，连接重置的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ （春季3环境，多部分文件上传）上传文件在测试环境（所有浏览器）中都能正常工作，并且只能在生产环境中使用Firefox（文件上传导致连接重置异常，尤其是低连接客户端的浏览器） 以下异常是在提交按钮之后几秒抛出按下：（浏览器是IE /浏览器在Windows环境中运行，但不是Firefox） org.springframework.web.multipart.MultipartException：无法分析多部分的servlet请求;嵌套的异常是org.apache.commons.fileupload.FileUploadBase $

解决方案您能捕获客户端和服务器之间的tcpdump并查看重置连接的人员。我们的应用程序中有类似的问题，它是一个防火墙，正在放弃连接。在apache [LimitRequestBody]中有另外一个设置，在文件上传达到限制之后放弃了上传。在这两种情况下，来自apache和mod-jk的日志在这些情况下调试并不那么明显。 I got a form belonging to a web app that

appreciate.Christophe D. 解决方案 Can you capture tcpdump between the client and server and see who is resetting the connection. We had a similar issue in our application and it was a firewall which was dropping the connection. There was another setting in apache [LimitRequestBody] which was aborting the upload after the file upload reached that limit. The logs from apache and mod-jk in these two cases were not that much clear to debug in these scenarios. 这篇关于弹出3上传文件问题 - MultipartException，连接重置的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！ 07-27 13:13
