我在使用大于2GB的文件上传HTTP文件时遇到问题。服务器和客户端都是64位，因此从系统角度来看，必须没有2GB的限制。我做了以下事情：
我正在使用apache commons文件上传。我还尝试使用ServerFileUpload setMaxFileSize方法设置最大文件大小。
我能够上传小于2GB的文件（我成功尝试了1.88GB文件）。请指点我，我在这里错过了什么？
更具体的说，ServletFileUpload.parseRequest方法在上传大文件时返回0 FileItems
以下是代码段：
if (isMultipartForm()) {
try {
DiskFileItemFactory factory = new DiskFileItemFactory();
factory.setSizeThreshold(SIZE_THRESHOLD);//SIZE_THRESHOLD = 4MB
ServletFileUpload upload = new ServletFileUpload(factory);
//upload.setFileSizeMax(3000000000L); Tried this too
upload.setProgressListener(progressListener);
items = upload.parseRequest(request);
if(items != null && items.size() == 0)
return new CommandResultSet(false, "NoItemsFoundInRequest");
return new CommandResultSet(true, "" + ( (items!=null) ? items.size() : ""));
} catch(FileUploadException e) {
e.printStackTrace();
System.out.println("Exception in MultipartFormManager. Can not parse request.");
return new CommandResultSet(false, e.getMessage());
}
}

如果您使用的是common-fileupload 1.1或更旧版本，则无法上传（1.9888）~2GB。这里的问题是这个jar正在调用一个名为getContentLength的方法，该方法是int类型，因此您的请求只能处理大小为Integer.MAX_VALUE的大小。在像1.3这样的common-fileupload的最新版本中，这已经解决了。 希望这会有所帮助。

我当然可能出现新的错误但我还没有发现即使64位浏览器也能处理大于2GB的上传。问题不是服务器而是浏览器。您会发现奇怪的是，大多数现代浏览器都会很乐意从标准服务器下载大于2GB的文件，无需特殊配置。

如果您希望上传这些尺寸的文件，我不会依赖直接的浏览器上传。 Java applet甚至可能是Flash文件（不确定，如果可能，不是Flash人员）将是我的建议，因此您可以将文件分成块。如果上传中断，您可以从上次停止的位置恢复。
