java为什么getRequest（）在Restservice中抛出NullPointerException？

Question

我有春季休息服务和方法重要付款：

  @RequestMapping(value = {"/importPayments"}, method = RequestMethod.POST)
    public Map<String, List<Payment>> importPayments() throws IOException {
        ImportPaymentsOutcome outcome = paymentService.importPayments(getRequest().getInputStream());
        ImportPaymentsOutcomeModel importPaymentsOutcome = new ImportPaymentsOutcomeModel(outcome);

如何获取请求并从中提取inputStream
当我尝试调用getRequest（）时，会出现NullPointerException

我尝试使用importPayments（HttpServletRequest请求）输入参数，但我需要使用空方法参数在新的参数上更改旧的REST
