SpringBoot 项目的两个不同模块之间

发送端

 //线程池
	private static ExecutorService executorService = new ThreadPoolExecutor(2, 200, 5, TimeUnit.SECONDS,
			new ArrayBlockingQueue<Runnable>(200), new ThreadPoolExecutor.DiscardOldestPolicy());
	/**
	 * 发送通知
	 * @param list
	 */
	public void sendTeacherMsg(List<xxxPo> list) {
		executorService.submit(new Runnable() {
			@Override
			public void run() {
				queueSender.send("xxx.xxxSender", JSON.toJSONString(list));
				logger.info("成功发送了一条 JMS 消息, List<xxxPo>总个数:" + JSON.toJSONString(list.size()));
			}
		});
	}

接收端

	/**
	 * @description 信息消息监听
	 */
	@JmsListener(destination = "xxx.xxxSender")
	@Override
	public void onMessage(Message message) {
		try {
			System.out.println("接受到了了");
			List<xxxPo> list = JSONObject.parseObject(((ObjectMessage) message).getObject().toString(), new TypeReference<List<xxxPo>>(){}.getType());
		
		} catch (JMSException e) {
			e.printStackTrace();
			log.error("QylZuowenListener 获取 JMS 消息失败", e);
		}
	}

发送端定时发送一次 但是，接收端却意外接受到 7 次,重启两个模块也还是这样

请问这个怎么解决
