Java Jersey不工作的文件上载

我无法将Jersey文件上传到工作中。使用泽西1.9。InputStream到达服务时为null。我尝试过将其作为一个普通表单提交和使用jQuery表单插件的AJAX提交，但结果都是一样的。也没有记录任何异常，这使它更加令人沮丧

HTML表单

<form id="docCategoryForm" name="docCategoryForm" action="someAction" method="post" enctype="multipart/form-data">
Document
<input type="file" name="fileupload_name" id="fileupload_name" >
<button id="submitButton" type="submit" title="Select to search">Submit</button>
</form>

如果我添加@FormDataParam（“fileupload_name”）formdatacontentdispositionfiledetail，我会得到很好的结果，但是InputStream仍然为null

以下是尝试上载简单文本文件后的请求。我觉得还可以

我想我应该结束这件事。这个问题最终变得非常愚蠢。不知何故，导入了错误的InputStream类。一旦我把它改为java.io.InputStream，它就如预期的那样工作了。
