ScheduledThreadPoolExecutor.delayedExecute介绍

[英]Main execution method for delayed or periodic tasks. If pool is shut down, rejects the task. Otherwise adds task to queue and starts a thread, if necessary, to run it. (We cannot prestart the thread to run the task because the task (probably) shouldn't be run yet.) If the pool is shut down while the task is being added, cancel and remove it if required by state and run-after-shutdown parameters.
[中]延迟或周期性任务的主要执行方法。如果池关闭，则拒绝该任务。否则会将任务添加到队列中，并在必要时启动一个线程来运行它。（我们不能预先启动线程来运行任务，因为任务（可能）还不应该运行。）如果在添加任务时关闭了池，请根据状态和关机后运行参数取消并删除它（如果需要）。
