多线程导致丢失header头信息

Question

 RequestAttributes requestAttributes = RequestContextHolder.currentRequestAttributes();
  ThreadPoolUtils.getThreadPool().execute(new Runnable() {
              @Override
             public void run() {
                       RequestContextHolder.setRequestAttributes(requestAttributes); 
                      CheckResult checkResult = checkService.execute(checkUrl, entity.getPsnCode());}

线程执行之前绑定了，然后执行完execute之后header头就丢失了，有人知道怎么回事吗

RequestContextHolder 是把数据放到ThreadLocal里面的实现吗
