Question about the controller

Sorry if I am completely wrong here but I have recently needed to learn the Spring Boot framework for work. I have Java experience but all of my web server stuff has been in Go.

That said I was looking at this line https://github.com/callicoder/spring-boot-file-upload-download-rest-api-example/blob/f3522aaa1d7dcc55e8526f1d1439e02f8ca982f7/src/main/java/com/example/filedemo/controller/FileController.java#L32-L51

Couldn't that be overloaded like this?

  @PostMapping(value = "/upload", params = {"file"})
  public UploadFileResponse uploadFile(@RequestParam MultipartFile file) {
    FileInstance fileInstance = fileStorageService.storeFile(file);

    String fileDownloadUri = ServletUriComponentsBuilder.fromCurrentContextPath()
      .path("/downloadFile/")
      .path(fileInstance.getId())
      .toUriString();
    
    return new UploadFileResponse(fileInstance.getFileName(), fileDownloadUri,
      file.getContentType(), file.getSize());
  }

  @PostMapping(value = "/upload", params = {"files"})
  public List<UploadFileResponse> uploadFile(@RequestParam MultipartFile[] files) {
    return Arrays.asList(files)
      .stream()
      .map(file -> uploadFile(file))
      .collect(Collectors.toList());
  }

If I am understanding things correctly that should allow a single endpoint to be used and it would auto use the correct upload?
