What is the method to recover Java asynchronous thread pool?

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

  1. Service that manages and executes tasks in a multithreaded environment.
  2. turn off or power down
  3. A service that allows for the execution of tasks.
  4. send in()
ExecutorService executorService = Executors.newCachedThreadPool();
// 关闭线程池
// 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
  1. 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) {

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