具有ThreadFactory和线程名称安全性的ExecutorService

Question

我正在尝试将名称设置为线程，但ExecutorService设置自己的名称（如pool-1-thread-1）。题 Naming threads and thread-pools of ExecutorService给出使用ThreadFactory的建议。 请你考虑这个解决方案，它足够安全吗？

public class Test {
    private volatile String prName;
    private volatile boolean prIsDaemon;

    private final ExecutorService pool = Executors.newCachedThreadPool(
        (Runnable r) -> {
            final Thread t = new Thread( r, prName );
            t.setDaemon( prIsDaemon );
            return t;
        }
    );

    public void Submit(boolean daemon, String name, Runnable run) {
        prIsDaemon = daemon;
        prName = name;
        pool.submit( run );
    }

    public void Shutdown() {
        pool.shutdown();
    }

    public static void main(String[] args) {
        final Test test = new Test();
        final Runnable r = () -> {
            System.out.println( Thread.currentThread().getName() );
        };
        test.Submit( false, "aaa", r );
        test.Submit( false, "bbb", r );
        test.Shutdown();
    }
}

结果：

aaa
bbb
