java - Spring Boot：Rest Template 400 错误请求

Question

我每 1 分钟尝试在调度程序中执行功能。调度程序的第一次调用给出了预期的结果，但在下一次迭代中得到 400 个错误请求。我在这里有用户名和密码。

   @Scheduled(cron = "0 0/1 * * * ?")
   public void xAuthTokenScheduler() throws Exception {
        String url="xxxx";
        String json= "jsonstring";
        restTemplate.getInterceptors().add(
                new BasicAuthorizationInterceptor(User.trim(),Password.trim()));
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_JSON);
        headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
        //headers.setContentType(MediaType.APPLICATION_JSON);
        headers.setCacheControl("no-cache, no-store, max-age=0, must-revalidate");
        HttpEntity<String> request = new HttpEntity<String>(json, headers);
        resultAsJsonStr= restTemplate.exchange(url, HttpMethod.POST,request,String.class);
    }

为什么它在第二次迭代中失败了任何与缓存相关的问题？
