IDEA的阿里巴巴规约插件提示：

“ 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。”

即：不能使用

ExecutorService excutorService = Executors.newCachedThreadPool();

改为ThreadPoolExecutor：

ThreadPoolExecutor pool1 = new ThreadPoolExecutor(5,200,60,
                TimeUnit.SECONDS,new ArrayBlockingQueue<Runnable> (5),Executors.defaultThreadFactory());

或 

ThreadFactory namedThreadFactory = new ThreadFactoryBuilder()
        .setNameFormat("demo-pool-%d").build();
ExecutorService pool = new ThreadPoolExecutor(5, 200,
        0L, TimeUnit.MILLISECONDS,
        new LinkedBlockingQueue<Runnable>(1024), namedThreadFactory, new ThreadPoolExecutor.AbortPolicy());

注意需要引入guava包，否则ThreadFactoryBuilder会报错 ：

<!-- https://mvnrepository.com/artifact/com.google.guava/guava -->
<dependency>
    <groupId>com.google.guava</groupId>
    <artifactId>guava</artifactId>
    <version>28.1-jre</version>
</dependency>
