    @RabbitListener(queues = "xiaomi")
    public void handlerXM(Message message,String msg, Channel channel) throws IOException {

        System.out.println("小米："+msg);

        //手动签收，不启动批量签收
        channel.basicAck(message.getMessageProperties().getDeliveryTag(),false);
    }


    @RabbitListener(queues = "huawei")
    public void handlerHW(Message message,String msg, Channel channel) throws IOException {


        System.out.println("华为："+msg);

        channel.basicAck(message.getMessageProperties().getDeliveryTag(),false);
