Exchange does not send MultiPartFile and explodes, the file is load in memory dosnt send in parts, this is the method, any idea?

  public void create(CreateCollectionRequest cmd) {
        final CreateCollectionRestModel request = CreateCollectionRestModel.from(cmd);
        log.info("Creating collection with {}", request);
        final URI uri = UriComponentsBuilder.fromUriString(config.Repository().getUrl() + COLLECTION_RESOURCE)
                .queryParam("code",160)
                .build().toUri();

        MultiValueMap<String, Object> body = new LinkedMultiValueMap<>();
        //File tempFile = File.createTempFile("xyz", "");
        //FileCopyUtils.copy(multipartFile.getInputStream(), new FileOutputStream(tempFile));

        body.add("file", cmd.getContent().getResource());
        HttpEntity<MultiValueMap<String, Object>> httpEntity =
                new HttpEntity<>(body, headersProvider.get("xxxx", "xxxx"));

        restTemplate.exchange(
                                uri,
                                HttpMethod.POST,
                                httpEntity,
                                Object.class)
                        .getBody();

Please format your code to make it more readable.
For java, it should look like this:

public void foo() {

}
