Send multipart file via RestTemplate
i have some problem about send image file (multipart) using android via Spring restTemplate.
here is my controller on server :
@RequestMapping(value = "/uploadPhoto/{id}", method = RequestMethod.POST)
@ResponseBody
public ResponseEntity<String> uploadPhoto(@RequestParam("file") MultipartFile srcFile,
@PathVariable("id") Integer id) {
/// do something
return RestUtil.getJsonSHttptatus(HttpStatus.NOT_ACCEPTABLE);
}
and this is rest request in my android activity
private void doUpload(){
new AsyncTask<String, Void, String>() {
@Override
protected String doInBackground(String... params) {
FormHttpMessageConverter formHttpMessageConverter = new FormHttpMessageConverter();
formHttpMessageConverter.setCharset(Charset.forName("UTF8"));
RestTemplate restTemplate = new RestTemplate();
restTemplate.getMessageConverters().add( formHttpMessageConverter );
restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
restTemplate.setRequestFactory(new HttpComponentsClientHttpRequestFactory());
String uri = "http://localhost:8089/web/uploadPhoto/1";
String imagePath = "/mnt/sdcard/DCIM/Camera/IMG_20140406_130350.jpg";
MultiValueMap<String, Object> map = new LinkedMultiValueMap<String, Object>();
map.add("expenseId", 1);
map.add("file", new FileSystemResource(path));
HttpHeaders imageHeaders = new HttpHeaders();
imageHeaders.setContentType(MediaType.MULTIPART_FORM_DATA);
HttpEntity<MultiValueMap<String, Object>> imageEntity = new HttpEntity<MultiValueMap<String, Object>>(map, imageHeaders);
restTemplate.exchange(uri, HttpMethod.POST, imageEntity, Boolean.class);
return "";
}
@Override
protected void onPostExecute(String result) {
Toast.makeText(MainActivity.this, "Data : "+result,
Toast.LENGTH_LONG).show();
}
}.execute();
}
I get this error :

Whats wrong with my code ? Any HttpMessageConverter for Multipart Request ?
thanks
FormHttpMessageConverter cannot write the expenseId part because it is an integer. Try sending it as a String:
map.add("expenseId", "1");
And receiving as a String:
@PathVariable("id") String id
There is a very similar question and answer here.
