线程池包含多个任务

代码如下
org.apache.rocketmq.client.impl.factory.MQClientInstance#startScheduledTask

private void startScheduledTask() {
   
        if (null == this.clientConfig.getNamesrvAddr()) {
   
            this.scheduledExecutorService.scheduleAtFixedRate(new Runnable() {
   

                @Override
                public void run() {
   
                    try {
   
                        MQClientInstance.this.mQClientAPIImpl.fetchNameServerAddr();
                    } catch (Exception e) {
   
                        log.error("ScheduledTask fetchNameServerAddr exception", e);
                    }
                }
            }, 1000 * 10, 1000 * 60 * 2, TimeUnit.MILLISECONDS);
        }

        this.scheduledExecutorService.scheduleAtFixedRate(new Runnable() {
   

            @Override
            public void run() {
   
                try {
   
                    MQClientInstance.this.updateTopicRouteInfoFromNameServer();
                } catch (Exception e) {
   
                    log.error("ScheduledTask updateTopicRouteInfoFromNameServer exception", e);
                }
            }
        }, 10, this.clientConfig.getPollNameServerInterval(), TimeUnit.MILLISECONDS);

        this.scheduledExecutorService.scheduleAtFixedRate(new Runnable() {
   

            @Override
            public void run() {
   
                try {
   
                    MQClientInstance
