客户端处理程序异常:找不到 MIME 媒体类型、多部分/表单数据

Question

我正在使用Jersey客户端来点击Spring MVC REST控制器以进行图像上传功能。我收到以下异常：

com.sun.jersey.api.client.ClientHandlerException: A message body writer for Java type, class org.springframework.web.multipart.commons.CommonsMultipartFile, and MIME media type, multipart/form-data, was not found

我的控制器发布映像的方法：

@RequestMapping(value = "/file/upload", method = RequestMethod.POST)
public String fileUpload(@RequestParam("fileUpload") MultipartFile file, 
Model model, HttpServletRequest request, HttpServletResponse response)
{
try
{   
ClientConfig config = new DefaultClientConfig();
com.sun.jersey.api.client.Client client = com.sun.jersey.api.client.Client.create(config);
WebResource webResource = client.resource("/save-image");
ClientResponse responseMsg = webResource
.type(MediaType.MULTIPART_FORM_DATA)
.post(ClientResponse.class, file);          
}
catch (Exception e)
{
logger.error("Exception in fileUpload()", e);
return "error";
}
return "success";
}

我的 REST 控制器方法获取发布数据：

@ResponseBody
@Consumes(MediaType.MULTIPART_FORM_DATA)
@RequestMapping(value = "/save-image", method = RequestMethod.POST)
public String saveImage(@FormDataParam("file") MultipartFile file, ModelMap 
model)
{
//Code to save the image
}

是否有此异常的解决方案。我已经根据以下堆栈解决方案进行了尝试，但仍然遇到相同的异常。
