使用org.apache.commons.fileupload上传附件 在本地及客户那边测试都没有问题
但客户实际开始使用时 时常会出现如下错误：
org.apache.commons.fileupload.FileUploadBase$IOFileUploadException: Processing of multipart/form-data request failed. Connection reset1、form中已经加入 enctype="multipart/form-data"
2、并不是每次附件都上传不成功
3、客户那边是用的双服务器，之间加的有ip映射 不知道会不会跟这个有关找了好久没有找到问题所在 希望大家帮忙分析下 谢谢

对外的访问ip既不是1的ip 也不是2的ip 应该是在硬件上做的ip映射（这个是硬件工程师做的 不太懂）我单独访问1和2的ip地址都是可以上传附件的
从日志中没有发现有找不到路径的情况额会不会跟代码有关呢？
感觉你这个东西对外是一个ip，但是1，2有不同的ip，可以看着，1，2是集群关系，当1，处理文件上传过程中繁忙，转发个2，处理，2这是没有找到响应的文件夹，所以报错，纯属猜测，你把全部异常贴出来，再具体描述下，1，2的网络关系

... 21 more这个是所有异常
1和2都是同一网段内的服务器 1是主服务器 存放上传文件的文件夹在1上面 设置为共享文件的
2服务器的上传路径直接指向的就是1上面的共享文件夹
ps #6 的图像真不错,!!!!
