Java 使用线程池

ExecutorService threadPool = new ThreadPoolExecutor(2, 5,
                1L, TimeUnit.SECONDS,
                new LinkedBlockingQueue<>(3),
                Executors.defaultThreadFactory(),
                new ThreadPoolExecutor.AbortPolicy());
        threadPool.execute(() -> {
            //---------线程执行内容
        });
        threadPool.shutdown();
