Spring mvc 上传文件，报The current request is not a multipart request

public UploadResponse upload(@RequestParam(required = false) MultipartFile zipFile, String token){...}

可见zipFile是要求为可传可不传的。

zipFile有文件上传，是成功的，如果zipFile是null的，就报：org.springframework.web.multipart.MultipartException: The current request is not a multipart request

解决方法

public UploadResponse upload(HttpServletRequest request, String token){MultipartFile pFile = null;CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver(request.getSession().getServletContext());if(multipartResolver.isMultipart(request)){    MultipartHttpServletRequest multiRequest = (MultipartHttpServletRequest)request;      pFile = multiRequest.getFileMap().get("pFile");}}
