xxljob里面如果使用了openfeign，则必须引入

    RequestContextHolder.setRequestAttributes(new ServletRequestAttributes(new MockHttpServletRequest()));

    @Autowired
    private IMessageSendClient           messageSendClient;


    @XxlJob("settlementAccountJob")
    public void settlementAccountJob() {
        RequestContextHolder.setRequestAttributes(new ServletRequestAttributes(new MockHttpServletRequest()));
        

        messageSendClient.sendMessage(MessageSendDTO.builder()
                .orderId(settlementItemEntity.getId())
                .userId(settlementItemEntity.getUserId())
                .userType(MsgUserType.ADMIN_USER)
                .eventType(MsgContent.NOTICE_SETTLEMENT_NOTE)
                .build());


        

}

feign接口使用CompletableFuture异步调用，请求上下文丢失处理

private static final ThreadPoolExecutor THREADPOOLEXECUTOR =
          new ThreadPoolExecutor (
                  100,
                  100,
                  100,
                  TimeUnit.SECONDS,
                  new ArrayBlockingQueue<> (1000));

  public static void main(String[] args) {
      RequestAttributes requestAttributes = RequestContextHolder.getRequestAttributes ();

      CompletableFuture<Void> task1 = CompletableFuture.runAsync (() -> {
          // 解决Feign异步调用丢失请求头的问题
          RequestContextHolder.setRequestAttributes (requestAttributes);

      }, THREADPOOLEXECUTOR);
      CompletableFuture<Void> task2 = CompletableFuture.runAsync (() -> {
          // 解决Feign异步调用丢失请求头的问题
          RequestContextHolder.setRequestAttributes (requestAttributes);

      }, THREADPOOLEXECUTOR);

      // 等待任务都完成
      try {
          CompletableFuture.allOf (task1, task2).get ();
      } catch (InterruptedException | ExecutionException e) {
          throw new RuntimeException (e);
      }

  }
