我需要取消Spring定时器执行或至少根据某些条件更改执行频率.正在使用org.springframework.scheduling.quartz.SimpleTriggerBean和org.springframework.scheduling.timer.ScheduledTimerTask.找不到怎么做的方法.

我需要覆盖Tree.js中的onClick方法.是否有任何常见的方法来覆盖dojo/dijit类方法？

我正在尝试实现一些逻辑,当我创建主(父)线程时,执行其他几个线程.然后它等待子线程创建的某些条件.在条件满足后,父亲执行更多的子线程.我在使用wait/notify时遇到java.lang.IllegalMonitorStateException异常的问题.这是代码:

public class MyExecutor {

final static ArrayBlockingQueue<Runnable> queue = new ArrayBlockingQueue<Runnable>(10);
final static ExecutorService svc = Executors.newFixedThreadPool(1);
static final ThreadPoolExecutor threadPool = new ThreadPoolExecutor(5, 8, 10, TimeUnit.SECONDS, queue);

public static void main(String[] args) throws InterruptedException {
    final MyExecutor me =  new MyExecutor();
    svc.execute(new Runnable()  {
        public void run() {
            try {
                System.out.println("Main Thread");
                me.execute(threadPool, 1);
                System.out.println("Main Thread waiting");
                wait();
                System.out.println("Main Thread notified");
                me.execute(threadPool, 2);
                Thread.sleep(100);
                threadPool.shutdown();
                threadPool.awaitTermination(20000, TimeUnit.SECONDS);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    });

    svc.shutdown();
    svc.awaitTermination(10000, …
