[FIXED] AWS S3 with Java – Reactive

Issue

I want to upload multipart file like here article. Here is my code

@RequestMapping(consumes = MediaType.MULTIPART_FORM_DATA_VALUE, method = {RequestMethod.POST, RequestMethod.PUT})
public Mono<ResponseEntity<UploadResult>> multipartUploadHandler(@RequestHeader HttpHeaders headers, @RequestBody Flux<Part> parts) {

    return parts
            .ofType(FilePart.class) // We'll ignore other data for now
            .flatMap((part) -> saveFile(headers, s3config.getBucket(), part))
            .collect(Collectors.toList())
            .map((keys) -> ResponseEntity.status(HttpStatus.CREATED)
                    .body(new UploadResult(HttpStatus.CREATED, keys)));
}

But when I send a request, i get 415

What could be the problem?

Solution

Change @RequestBody Flux<Part> parts to @RequestPart("file") Flux<FilePart> parts fix all of this
