I am trying to upload a File using RestTemplate with the following code. 

   MultiValueMap<String, Object> multipartMap = new LinkedMultiValueMap<>();
   multipartMap.add("file", new ClassPathResource(file));

   HttpHeaders headers = new HttpHeaders();
   headers.setContentType(new MediaType("multipart", "form-data"));

   HttpEntity<MultiValueMap<String, Object>> request = new HttpEntity<MultiValueMap<String, Object>>(multipartMap, headers);

   System.out.println("Request for File Upload : " + request);

   ResponseEntity<byte[]> result = template.get().exchange(
                    contextPath.get() + path, HttpMethod.POST, request,
                    byte[].class);

I have the MultipartResolver bean and Controller code is 

@RequestMapping(value = "/{id}/image", method = RequestMethod.POST)
@ResponseStatus(HttpStatus.NO_CONTENT)
@Transactional(rollbackFor = Exception.class)
public byte[] setImage(@PathVariable("id") Long userId,
        @RequestParam("file") MultipartFile file) throws IOException {
    // Upload logic
}

And I get the following Exception

 org.springframework.web.bind.MissingServletRequestParameterException: Required MultipartFile parameter 'file' is not present

The Multipart File Upload worked after following code modification to Upload using RestTemplate

LinkedMultiValueMap<String, Object> map = new LinkedMultiValueMap<>();
map.add("file", new ClassPathResource(file));
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.MULTIPART_FORM_DATA);

HttpEntity<LinkedMultiValueMap<String, Object>> requestEntity = new    HttpEntity<LinkedMultiValueMap<String, Object>>(
                    map, headers);
ResponseEntity<String> result = template.get().exchange(
                    contextPath.get() + path, HttpMethod.POST, requestEntity,
                    String.class);

And adding MultipartFilter to web.xml

    <filter>
        <filter-name>multipartFilter</filter-name>
        <filter-class>org.springframework.web.multipart.support.MultipartFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>multipartFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
