（使用newScheduledThreadPool来模拟心跳机制）
1 public class HeartBeat {
2 public static void main(String[] args) {
3 ScheduledExecutorService executor = Executors.newScheduledThreadPool(5);
4 Runnable task = new Runnable() {
5 public void run() {
6 System.out.println("HeartBeat.........................");
7 }
8 };
9 executor.scheduleAtFixedRate(task,5,3, TimeUnit.SECONDS); //5秒后第一次执行，之后每隔3秒执行一次
10 }
11 }
HeartBeat....................... //5秒后第一次输出 HeartBeat....................... //每隔3秒输出一个
