java - ClientHandlerException : MIME media type, 多部分/表单数据，未找到

Question

我正在使用 Jersey 客户端来访问 Spring MVC REST Controller 以实现图像上传功能。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 Controller 方法来发布图像:

@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 Controller 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
}

这个异常有解决办法吗？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。

Jersey client exception: A message body writer was not found
