多文件上传程序Jquery多部分解析器不工作

我试图上传一个文件到我的前端系统，作为测试，将其保存到我的C驱动器的本地文件夹中。我有ajax函数和controller方法，但似乎无法找出spring日志中错误消息的含义

Ajax功能：

    function makeProgress(){                    
      var url = getRelativeURL("web/fileUpload");        
      var formData = new FormData();
      formData.append('file', $('input[type=file]')[0].files[0]);
      console.log("form data " + formData);
      $.ajax({
          url : url,
          data : formData,
          processData : false,
          contentType : "multipart/form-data",
          type : 'POST',
          success : function(data) {
              alert(data);
          },
          error : function(err) {
              alert(err);
          }
     });

        }

服务器端控制器：

private static String UPLOADED_FOLDER = "C://temp//";

@RequestMapping(value = { "/fileUpload" }, method = RequestMethod.POST, consumes ={"multipart/form-data"})
@ResponseBody
public String uploadFile(@RequestParam("file") MultipartFile file, HttpServletRequest req, HttpServletResponse res)
{       
    try {

            byte[] bytes = file.getBytes();
            Path path = Paths.get(UPLOADED_FOLDER + file.getOriginalFilename());
            Files.write(path, bytes);
            logger.info("You have successfully uploaded '" + file.getOriginalFilename() + "'");
            return("File Uploaded");


    } catch (Exception e) {
        res.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
        logger.error("Failed to upload file '" + file.getOriginalFilename() + "'", e);
        return("File Not Uploaded");
    }
}

错误日志：

2017-04-10 10:30:09.758 DEBUG o.s.web.servlet.DispatcherServlet.976 - Could not complete request 
java.lang.IllegalArgumentException: Expected MultipartHttpServletRequest: is a MultipartResolver configured?

有人能看到我缺少什么吗？

请显示您的配置。@Bean（name=“multipartResolver”）public commons多部分解析器commons多部分解析器commonmultipartresolver（）{commonmultipartresolver commonmultipartresolver=new commonmultipartresolver（）；commonmultipartresolver.setDefaultEncoding（“utf-8”）；commonMultipartResolver.setMaxUploadSize（50000000）；return commonMultipartResolver；}}2017-04-10 11:07:56.021 DEBUG o.s.web.servlet.DispatcherServlet.976-无法完成请求org.springframework.web.multipart.MultipartException:无法解析多部分servlet请求；嵌套的异常是org.apache.commons.fileupload.FileUploadException：请求被拒绝，因为在org.springframework.web.multipart.commons.commonmultipartresolver.parseRequest（commonmultipartresolver.java:163）~[spring-web-3.2.8.RELEASE.jar:3.2.8.RELEASE]@alfcope是否对配置提供了上述帮助？您的请求似乎有误。应ajax请求，将

contentType

设置为false。看看这个答案
