多部分POST请求

Question

@RequestMapping(value = Constants.REQMAP_CON_FILE_UPLOAD, method = RequestMethod.POST, headers=("content-type=multipart/form-data"), consumes = "multipart/form-data" } )

        HealthVaultResponse uploadFile(
                @PathVariable Long consumerFolderId,
                @PathVariable Long consumerUserId,
                @PathVariable Long reportTitleId,
                @RequestParam("file") MultipartFile file ,HttpServletRequest request) throws Exception {

Client error: `POST http://172.16.2.67:8080/api/v1/uploadFile/1/0/5/` resulted in a `400 Bad Request` response:
{"status":{"statusCode":-400,"message":"Invalid Request, Media Type Not Supported","localizedMessage":"Invalid Request, (...)

可能是什么问题？
