FileUpload（Apache Commons）和Java POI IOException：无法读取整个标头
[英]FileUpload (Apache Commons) and Java POI IOException: Unable to read entire header
问题描述
I'm trying to user Apache Commons Streaming API to get the information from an excel spreadsheet. 
我正在尝试使用Apache Commons Streaming API从Excel电子表格中获取信息。 I keep on getting the following error: 我不断收到以下错误：

This how my form looks: 这是我的表格的样子：
<form action="ReportServlet" method="post" enctype="multipart/form-data">
<input type="file" name="file"/>
<br />
<input type="submit" value="Upload Report" name="upload_report_btn" />
</form>
I'm using glassfish. 我在用玻璃鱼。 Any ideas why I keep on getting this message? 有什么想法让我继续收到此消息吗？

In your loop you seem to be assuming that the first and only multipart object arriving will be the spreadsheet file. 在循环中，您似乎假设第一个也是唯一的多部分对象将是电子表格文件。 The form itself will be present as well. 表单本身也将存在。 The clue is the message 线索就是信息
Unable to read entire header; 13 bytes read; expected 512 bytes
Notice, the form's uploaded value is Upload Report , which happens to be 13 bytes long. 请注意，表单的上载值是Upload Report ，恰好是13个字节长。
You could have easily seen this if you used a browser-based debugging tool such as Firebug or Fiddler. 如果您使用了基于浏览器的调试工具（例如Firebug或Fiddler），您可能会很容易看到这一点。 One of these tools should be in your tool-set. 这些工具之一应该在您的工具集中。
