tomcat停止但线程还活着；
当tomcat停止时如何停止线程？

Answer 1

在 contextDestroyed 上的 servletcontextlistener 中的执行程序服务上调用 shutdownNow，这将中断池中的线程。看到这个问题: how to catch the event of shutting down of tomcat?

但是您的 Customer Runnable 不会停止它正在做的事情来响应中断，所以关闭线程池不会导致它退出。更改Customer的run方法，在检测到中断标志时退出循环:

while (!Thread.currentThread().isInterrupted()) {
    try {
        Thread.sleep(5000);
    } catch (InterruptedException e) {
        Thread.currentThread().interrupt();
    }
}
