In Java, asynchronous thread pools can be restored using the following method:

Service that manages and executes tasks in a multithreaded environment.
turn off or power down
A service that allows for the execution of tasks.
send in()

ExecutorService executorService = Executors.newCachedThreadPool();
// 关闭线程池
executorService.shutdown();
// 等待所有任务执行完成
executorService.awaitTermination(Long.MAX_VALUE, TimeUnit.NANOSECONDS);
// 重新提交任务
executorService.submit(() -> {
    // 异步任务逻辑
});

terminate immediately

ExecutorService executorService = Executors.newCachedThreadPool();
// 关闭线程池，并返回未执行的任务列表
List<Runnable> tasks = executorService.shutdownNow();
// 创建一个新的线程池
executorService = Executors.newCachedThreadPool();
// 重新提交未执行的任务
for (Runnable task : tasks) {
    executorService.submit(task);
}

These methods can be used to restore the functionality of the asynchronous thread pool for executing tasks again.
