ScheduledExecutorService工作线程在FutureTask之后保留中断状态。取消(真)

* How is it that the worker thread is left in a state where the interrupt status is set?
* Why does the default implementation not clear the interrupt status before starting a new task?

答案是:

• 它不会处于中断状态。
• 实现确实如此,但您没有找到正确的位置

从Oracle库代码:

        /*
         * Ensure that unless pool is stopping, this thread
         * does not have its interrupt set. This requires a
         * double-check of state in case the interrupt was
         * cleared concurrently with a shutdownNow -- if so,
         * the interrupt is re-enabled.
         */
        if (runState < STOP &&
            Thread.interrupted() &&
            runState >= STOP)
            thread.interrupt();

如您所见,只要执行器不关闭,中断状态就会从工作线程中清除。

用户如何中断线程?如果他们使用的是UI组件,那么您的问题可能是由于事件分派线程的同步问题造成的。
