Java Executors:如何设置任务优先级？

import java.util.concurrent.*;

public class PriorityTask implements Comparable<PriorityTask> {
    private int priority;
    private String taskName;

    public PriorityTask(int priority, String taskName) {
        this.priority = priority;
        this.taskName = taskName;
    }

    public int getPriority() {
        return priority;
    }

    public String getTaskName() {
        return taskName;
    }

    @Override
    public int compareTo(PriorityTask other) {
        return Integer.compare(other.getPriority(), this.getPriority());
    }

    public static void main(String[] args) {
        ExecutorService executorService = Executors.newFixedThreadPool(5, new ThreadFactory() {
            @Override
            public Thread newThread(Runnable r) {
                return new Thread(r);
            }
        });

        PriorityBlockingQueue<PriorityTask> taskQueue = new PriorityBlockingQueue<>();

        taskQueue.add(new PriorityTask(1, "Task 1"));
        taskQueue.add(new PriorityTask(3, "Task 2"));
        taskQueue.add(new PriorityTask(2, "Task 3"));

        while (!taskQueue.isEmpty()) {
            PriorityTask task = taskQueue.poll();
            executorService.execute(new Runnable() {
                @Override
                public void run() {
                    System.out.println("Executing task: " + task.getTaskName());
                }
            });
        }

        executorService.shutdown();
    }
}
