控制ExecutorService每秒最多执行N个任务

假设您为每个任务创建一条SMS消息，则可以使用ScheduleExecutorService。

final Queue<Task> tasks = new ConcurrentlinkedQueue<Task>();int ratePerSecond = 10;final ExecutorService es = Executors.newCachedThreadPool();ScheduledExecutorService ses = Executors.newSingleThreadScheduledExecutor();ses.scheduleAtFixedRate(new Runnable() {    @Override    public void run() {        final Task task = tasks.poll();        if (task == null) return;        es.submit(new Runnable() { @Override public void run() {     process(task); }        });    }}, 0, 1000/ratePerSecond, TimeUnit.MILLISECONDS);

将任务添加到队列中，它们将以每秒10个的速度处理。
