我使用缓存线程池ExecutorService来运行一些异步后台任务.我已经提供了我的ThreadFactory,它将线程分发给ExecutorService(只要它需要它们).我对缓存线程池的理解是,在线程空闲60秒后,它由ExecutorService终止.

当我的线程即将被终止时,我想执行一些状态清理.实现这一目标的最佳方法是什么？ExecutorService不容易为线程的生命周期提供钩子.

我不想关闭我的ExecutorService - 对于在它们到来时运行任务非常有用.

ExecutorService executor = Executors.newCachedThreadPool(new MyThreadFactory());

// Do some work
executor.submit(new MyCallable());

// Need a way for the ExecutorService to notify me when it is about to
// terminate my thread - need to perform some cleanup

谢谢,
