损坏的表单数据:过早结束 [英] Corrupt form data: premature ending

问题描述

我正在尝试使用 FileReference 类上传文件.大于 2MB 的文件都可以正常工作，但小于 2MB 的文件会导致此错误:

I am trying to upload files using the FileReference class. Files >2MB all work correctly but files <2MB cause this error:

"java.io.IOException: 损坏的表单数据:提前结束"

"java.io.IOException: Corrupt form data: premature ending"

在服务器上，我使用 com.oreilly.servlet 包来处理请求.

On the server I am using the com.oreilly.servlet package to handle the request.

我已经多次使用这个包来成功处理来自 flex 的文件上传，但由于某种原因，现在我遇到了这个问题.

I have used this package many times to successfully handle file uploads from flex, but for some reason, now I am having this problem.

这是一些更多信息的堆栈跟踪:

推荐答案

com.orielly.servlet.MultipartRequest 类和 org.apache.struts2.dispatcher.ActionContextCleanUp 过滤器一起使用时，似乎存在一个错误.这就是导致小文件上传失败的原因.

It seems that there is a bug that exists when using com.orielly.servlet.MultipartRequest class and the org.apache.struts2.dispatcher.ActionContextCleanUp filter together. This is what was causing small file uploads to fail.
