Как передать идентификатор в контроллере для экспорта файла CSV

Question

Я использую Spring boot 1.5, и я пытаюсь экспортировать CSV-файл, используя этот код, но не знаю, как передать идентификатор, который я получаю из внешнего интерфейса в контроллере, я провел некоторые исследования, но втщетно, спасибо за помощь!

@Override
    public InputStream exportAlerts(Long id) throws IOException {
      List<ExportSuggestVO> exportSuggestVOS = new ArrayList<>();

    final String[] header = new String[]{"id", "alertStatus", "addedBy", "addedByEmail", "uo", "added" };
    final CellProcessor[] processors = getProcessors();
    Alert alert = alertRepository.findById(id);
    {
        OrganisationUnitVO organisationUnitVO = null;
        try {
            organisationUnitVO = userFromUoProvider.getSite(alert.getAddedBy());
        } catch (Exception e) {
            logger.error("not found", e);
        }

        exportSuggestVOS.add(new ExportSuggestVO.Builder()
        .setId(alert.getId() == null ? null : alert.getId())
        .setAlertStatus(alert.getAlertStatus() == null ? null : alert.getAlertStatus().getLabel())
        .setAddedBy(String.valueOf(getEmployeeDetails(alert.getAddedBy())))
        .setAddedByEmail(getEmployeeDetails(alert.getAddedBy()) == null ? " "
                : getEmployeeDetails(alert.getAddedBy()).getEmail())
        .setUo(organisationUnitVO == null ? " " : organisationUnitVO.getName())
        .setAdded(alert.getAdded() == null ? "" : alert.getAdded().toString().replace("T"," "))
        .build());}
    ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
    CsvBeanWriter beanWriter = null;
    try{
        beanWriter = new CsvBeanWriter(new OutputStreamWriter(outputStream, "ISO-8859-1"),
                CsvPreference.EXCEL_NORTH_EUROPE_PREFERENCE);
        beanWriter.writeHeader("id", "Status", "Auteur", "Auteur-email", "Site/UO", "Date création");
        for (ExportSuggestVO exportSuggestVO : exportSuggestVOS){
            beanWriter.write(exportSuggestVO, header,processors);
        }
    } finally {
        if (beanWriter != null){
            beanWriter.close();
        }
    }
    return new ByteArrayInputStream(outputStream.toByteArray()); }

контроллер

    @RequestMapping(value = "/downloadAlert", method = RequestMethod.POST)
public void exportAllSuggest(HttpServletResponse response)
        throws IOException {
    InputStream in = alertService.exportAlerts();
    try {
        response.setContentType("text/csv;charset=UTF-8");
        response.addHeader("Content-Disposition", "attachment; filename = Alerts" + LocalDate.now() + ".csv");
        OutputStream outputStream = response.getOutputStream();

        IOUtils.copy(new BufferedInputStream(in), outputStream);
        in.close();
        outputStream.flush();
        outputStream.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
