Java でスレッド プールとタスク スケジュールの問題を解決する方法

ThreadPoolExecutor threadPool = new ThreadPoolExecutor(
    corePoolSize,
    maximumPoolSize,
    keepAliveTime,
    TimeUnit.MILLISECONDS,
    new LinkedBlockingQueue<Runnable>()
);

threadPool.submit(new Runnable() {
    public void run() {
        // 任务执行的逻辑代码
    }
});

threadPool.shutdown();

ScheduledExecutorService scheduledExecutor = Executors.newScheduledThreadPool(1);
scheduledExecutor.schedule(new Runnable() {
    public void run() {
        // 在延时后执行的逻辑代码
    }
}, delay, TimeUnit.MILLISECONDS);

ScheduledExecutorService scheduledExecutor = Executors.newScheduledThreadPool(1);
scheduledExecutor.scheduleAtFixedRate(new Runnable() {
    public void run() {
        // 周期性执行的逻辑代码
    }
}, initialDelay, period, TimeUnit.MILLISECONDS);

scheduledExecutor.shutdown();

// 创建线程池
ThreadPoolExecutor threadPool = new ThreadPoolExecutor(
    corePoolSize,
    maximumPoolSize,
    keepAliveTime,
    TimeUnit.MILLISECONDS,
    new LinkedBlockingQueue<Runnable>()
);

// 创建任务调度器
ScheduledExecutorService scheduledExecutor = Executors.newScheduledThreadPool(1);

// 提交任务到线程池
threadPool.submit(new Runnable() {
    public void run() {
        // 后台数据处理的逻辑代码
    }
});

// 延时调度任务
scheduledExecutor.schedule(new Runnable() {
    public void run() {
        // 定时清理数据的逻辑代码
    }
}, delay, TimeUnit.MILLISECONDS);

// 关闭线程池和任务调度器
threadPool.shutdown();
scheduledExecutor.shutdown();
