线程池创建方式

1.ScheduledExecutorService

 ScheduledExecutorService executorService = new ScheduledThreadPoolExecutor(1,new BasicThreadFactory.Builder().namingPattern("example-schedule-pool-%d").daemon(true).build());

2.ExecutorService

ThreadFactory namedThreadFactory = new ThreadFactoryBuilder().setNameFormat("demo-pool-%d").build();

//Common Thread Pool
ExecutorService pool = new ThreadPoolExecutor(5, 200,0L, TimeUnit.MILLISECONDS, new LinkedBlockingQueue<Runnable>(1024), namedThreadFactory, new ThreadPoolExecutor.AbortPolicy());

pool.execute(()-> System.out.println(Thread.currentThread().getName()));

// 关闭线程池
pool.shutdown();

• 使用Executor创建的线程池允许的请求队列长度为Integer.MAX_VALUE，可能会堆积大量的请求，从而引起OOM异常
