我正在使用
* jquery 1.7.1 * jquery 表单用于使用 ajax * Jersey 1.8
的 multipart/form-data 。 以下是我的 html 代码：

    <html>
    <head>
     <!-- <script src="jquery-1.4.2.js" type="text/javascript" charset="utf-8"></script> -->
     <script src="js/jquery-1.7.1.min.js" type="text/javascript"></script>
       <script src="js/main.js" type="text/javascript"></script>
     <script src="js/jquery.form.js" type="text/javascript"></script>
    </head>
    <body>
    <div id="output">
    </div>
    <form encType="multipart/form-data" method="POST" id="userForm">
    <label>Image file : </label>
    <input type="file" id="file1" name="file1"/>
    <input type="submit" id="btnCreate" name="btnCreate"/>
   </form>
   </body>
   </html>

以下是我的 javascript 代码：

  jQuery.support.cors = true;
  var rootURL = "http://localhost:8084/UserDemo/webresources/user";
  $(document).ready(function() { 
        var options = { 
              target:        "#output",   // target element(s) to be updated with server response 
             beforeSubmit:  showRequest,  // pre-submit callback 
             success:       showResponse,  // post-submit callback 
     error: errorResponse,
      url : rootURL,
      dataType :  "json"
     }; 
     $('#userForm').ajaxForm(options); 
 }); 
    function errorResponse(responseText,statusText,xhr,$form)
     {
        alert("responseText : " + responseText +" : statusText : " + statusText);
     }
     // pre-submit callback 
   function showRequest(formData, jqForm, options) { 

      var queryString = $.param(formData); 
       alert('About to submit: \n\n' + queryString); 
         return true; 
     } 

    // post-submit callback 
    function showResponse(responseText, statusText, xhr, $form)  { 

         alert('status: ' + statusText + '\n\nresponseText: \n' + responseText + 
    '\n\nThe output div should have already been updated with the responseText.'); 
    }

这是我的球衣网络服务代码片段

        @POST
        @Consumes({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML,MediaType.MULTIPART_FORM_DATA, MediaType.APPLICATION_OCTET_STREAM})
@Produces({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML, MediaType.MULTIPART_FORM_DATA })
            //public User create(@FormParam("file") InputStream  user) {
            public User create(User  user1) {
               //User user = (User)user1;
          System.out.println("creating user");
                  return new User();
            //return dao.create(user);
       }

在服务器日志中，我收到以下消息：

请帮助我找到问题的根本原因

因为您使用的是“multipart/form-data”内容类型，所以您应该使用 @FormDataParam 来获取表单数据：

@POST
@Consumes("multipart/form-data")
@Produces({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML, MediaType.MULTIPART_FORM_DATA })
public User create(@FormDataParam("file") InputStream  user) { 
      //analyse your user binary data    
      System.out.println("creating user");
      return new User();
}
