另外开一个线程跑多线程

 

public static ScheduledExecutorService executorService=Executors.newScheduledThreadPool(1);

private static SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd hh:mm:ss.SSS");
public static void main(String[] args) {
Runnable runnable =new Runnable() {
public void run() {
//业务逻辑处理
System.out.println("newScheduledThreadPool:"+sdf.format(new Date()));
}
};
executorService.scheduleAtFixedRate(runnable,0, 3, TimeUnit.SECONDS);
}
