jquery uploadify ie9问题多部分未发送到服务器

我正在使用jquery uploadify在基于Spring MVC的angular应用程序中上传图像

图像上传在除IE9之外的所有浏览器中都能完美运行

在IE9的情况下，我在服务器上得到以下错误

org.springframework.web.multipart.MultipartException: The current request is not a multipart request

但同样的代码片段在其他浏览器和IE 10中也能很好地工作

谁能给我指一下正确的方向。

<script type="text/javascript" src="resources/scripts/jqueryUploadify/jquery.Jcrop.min.js"></script>
<script type="text/javascript" src="resources/scripts/jqueryUploadify/jquery.ui.widget.js"></script>

<!--[if gte IE 8]><script src="resources/scripts/jqueryUploadify/jquery.xdr-transport.js"></script><![endif]-->

<link rel="stylesheet" href="resources/scripts/jqueryUploadify/jquery.Jcrop.css">
<link rel="stylesheet" href="resources/scripts/jqueryUploadify/jquery.fileupload-ui.css">

我之前遗漏了几个javascript文件，这导致了一个问题，在包含了所有上述文件后，问题现在得到了解决
