不推荐的使用方式

# 提示手动创建线程池，效果会更好哦。
ExecutorService fixedThreadPool = Executors.newFixedThreadPool(10);

Inspection info:
线程池不允许使用Executors去创建，而是通过ThreadPoolExecutor的方式，这样的处理方式让写的同学更加明确线程池的运行规则，规避资源耗尽的风险。 说明：Executors各个方法的弊端：
1）newFixedThreadPool和newSingleThreadExecutor:
主要问题是堆积的请求处理队列可能会耗费非常大的内存，甚至OOM。
2）newCachedThreadPool和newScheduledThreadPool:
主要问题是线程数最大数是Integer.MAX_VALUE，可能会创建数量非常多的线程，甚至OOM。

# 推荐使用案例：
     ScheduledExecutorService executorService = new ScheduledThreadPoolExecutor(1,
            new BasicThreadFactory.Builder().namingPattern("example-schedule-pool-%d").daemon(true).build());
    
    # 推荐使用案例：
        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()));
        pool.shutdown();//gracefully shutdown

最佳实践

ThreadFactory namedThreadFactory = new ThreadFactoryBuilder().setNameFormat("thread-call-runner-%d").build();

ExecutorService fixedThreadPool = new ThreadPoolExecutor(10,20,200L,TimeUnit.MILLISECONDS,new LinkedBlockingQueue<Runnable>(),namedThreadFactory);
