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。
