正在尝试上载文件，但请求未发送

Question

我正在尝试使用file类型的输入上传文件，我还有另一个参数要提交

以下是我的表格代码：

<form  id="fileupload" action="uploadMassContentsFromExcelSheetNew"  method="post" 
  enctype="multipart/form-data" onsubmit="return doMassValidate();"  >          

      <input type="hidden" id="fileName" name="fileName" value=""/>
      <input type="hidden" id="serviceIdMass" name="serviceIdMass"   value=""/>
      <input type="hidden" id="contentTypeMass" name="contentTypeMass"   value=""/> 



     <div id='fileDiv' class="row fileupload-buttonbar">
        <div class="col-md-12 col-xs-12 col-lg-12">
        <div class="input-group input-group-file">
        <input type="text" class="form-control" 
                        disabled="disabled" id="uploadFile" name="uploadFile">
        <span class="input-group-btn">
             <span class="btn btn-primary btn-file">
        <i class="icon md-upload" aria-hidden="true"></i>
      <input type="file" name="files" id="uploadBtn">
          </span>
          </span>   
        <p style="word-wrap: break-word;">
            <small id="fileError" style="display: none;"
                            class="help-block" data-fv-validator="notEmpty"
                            data-fv-result="VALIDATED">
                <s:property value="getText('content.file.error')" />
            </small>
        </p>

        </div>
        </div>
     </div> 

            <button  name="sub" type="submit" >submit</button>

</form>

JS代码：

function doMassValidate(){
    var hasSelectedFile=checkIfHasSelectedFile();
    if(!hasSelectedFile){
        fileErrorMessage();
        $("#fileError").hide();

        return false;
    }
    else{
        removeErrorClass('fileDiv');
        return true;
    }
}
function checkIfHasSelectedFile(){
    var hasNotUploadFile=   $('#uploadBtn').val(); 
    if(hasNotUploadFile=="" || hasNotUploadFile=='' )
         return false;
     else return true;

}

这是我的行动：

public String uploadMassContentsFromExcelSheetNew() {
    HSSFSheet sheet = null;
    HSSFWorkbook workbook = null;
    FileInputStream inputStream = null;
    result=new JSONObject();

    try {
            if (fileName != null){
            fileName=fileName.trim();

        if  (fileName.endsWith(".xls") || fileName.endsWith(".xlsx") )  {

    HttpServletRequest request = ServletActionContext.getRequest();
                System.out.println("Parts*******:"+request.getParts()); //return   null


                MultiPartRequestWrapper multiWrapper=(MultiPartRequestWrapper)ServletActionContext.getRequest();
            String fileNameParam=servletRequest.getParameter("fileName");//i get the file name value
String fileParam=servletRequest.getParameter("files");// i cant get param with name "files" when i inspect the servletRequest

            Part filePart =request.getPart("files");//return null
            File[] f=multiWrapper.getFiles("files"); //return null
            String fileName=multiWrapper.getFileNames("files")[0];
            Enumeration fileParameterNames = multiWrapper.getParameterNames();
            String param = request.getParameter("files");
        }
            }
    }
    catch(Exception ex){
        ex.printStackTrace();
    }
}       

和IM使用fileUpload拦截器：

<interceptor-ref name="fileUpload"/>
<interceptor-ref name="basicStack"/>

这是请求：

------WebKitFormBoundaryjBpjIWpSdq4RzL0X
Content-Disposition: form-data; name="fileName"

C:\fakepath\SMSMassploadOladDate.xls
------WebKitFormBoundaryjBpjIWpSdq4RzL0X
Content-Disposition: form-data; name="serviceIdMass"

647
------WebKitFormBoundaryjBpjIWpSdq4RzL0X
Content-Disposition: form-data; name="contentTypeMass"

1

------WebKitFormBoundaryjBpjIWpSdq4RzL0X
Content-Disposition: form-data; name="files"; filename=""
Content-Type: application/octet-stream

文件内容类型不应该是“application/ms-excel，application/vnd.ms-excel”而不是application/octet-stream？文件名不应该是空的？

我真的不明白文件有什么问题？

我已经用struts解决了这个问题。xml i只是扩展了“struts默认值”，它应该扩展为“struts默认值，json默认值”。另外，它与blueimp插件有关，我试图使用调用的“main.js”库使我的代码无法工作。
