我的代碼是這樣的：ScheduledExecutorService executor = Executors.newScheduledThreadPool(8);//complex code that call this multiple times too add tasks:executor.schedule(() -> { doRealTask(); }, 0, TimeUnit.MICROSECONDS);//drain the pool on some condition, e.g. meets tasks that can't be parallelized:executor.shutdown();//without this, awaitTermination won't return since all the threads in the pool will be paused, not terminatedexecutor.awaitTermination(1000000, TimeUnit.SECONDS);//continue to add more tasks:executor.schedule(...);最后一個(gè)代碼拋出 java.util.concurrent.RejectedExecutionException 。原因似乎是執(zhí)行器已關(guān)閉。但沒(méi)有“startAgain”功能。顯然創(chuàng)建一個(gè)新的 ScheduledExecutorService 是有效的，但我覺(jué)得我使用了錯(cuò)誤的解決方案。如何在Java中實(shí)現(xiàn)這個(gè)？
