表单数据损坏：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。文件> 2MB都可以正常工作，但文件< 2MB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：表单数据损坏：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.

我已经多次使用此软件包来成功处理来自flex的文件上传，但是由于某种原因，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.

推荐答案

是个虫子一起使用com.orielly.servlet.MultipartRequest类和org.apache.struts2.dispatcher.ActionContextCleanUp过滤器时，存在。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.
