Проблема с открытие файлов загруженных на сервер в Spring Boot

Есть Controller в котором через @GetMapping обрабатываю страницу

orders/{id}/upload

где реализован следующий функционал.

Выводится список файлов со ссылками на эти файлы из директории

src/main/resources/static/layout/{id}/

и реализована форма multipart form, через которою происходит загрузка файлов на сервер в указанную выше папку в RestController через @PostMapping.

Проблема такая:
Когда я загружаю файл на сервер, он попадает в список файлов, но если я перехожу по ссылке, выпадает ошибка 404, хотя файл на сервере есть.

Я перезагружаю сервер и ссылка начинает работать (адрес ссылки не меняется).

Подскажите, в чем может быть проблема?

@Controller
public class OrderController {
  @GetMapping("/orders/{id}/upload")
  public String upload(@PathVariable(value = "id") long id, Model model) {
    model.addAttribute("order_number", id);
    String directory = "src/main/resources/static/layout/" + id + "/";
    File file = new File(directory);
    if (!file.exists()) {
        file.mkdirs();
    }
    File[] listFiles = file.listFiles();
    model.addAttribute("listfile", listFiles);
    return "upload";
  }
}

.

@Service
public class FileUploadService {
    public void uploadFile(MultipartFile file, long id) throws IOException {
        File uploadFile = new File("/Users/prisukhin/Documents/printing/src/main/resources/static/layout/" + id + "/" + file.getOriginalFilename());
        if(file != null) {
            file.transferTo(uploadFile);
        }
    }
}

.

@RestController
public class FileUploadRestController {

    @Autowired
    FileUploadService fileUploadService;

    @PostMapping("/orders/{id}/upload")
    public RedirectView fileUpload(@PathVariable(value = "id") long id, @RequestParam MultipartFile file_form, Model model) throws IOException {
        fileUploadService.uploadFile(file_form, id);
        return new RedirectView("/orders/{id}/upload");
    }

часть файла upload.html

<table class="table table-hover">
