获取线程中抛出的异常信息

       ScheduledExecutorService service = Executors.newScheduledThreadPool(10);
        // 从现在开始delay毫秒之后，每隔一天执行一次，转换为毫秒
        // service.scheduleAtFixedRate(this, delay, period, TimeUnit.MILLISECONDS);
        /**获得线程中抛出的异常，eg Integer.parseInt("AAA");,缺少jar包等*/
        ScheduledFuture<?> future = service.scheduleAtFixedRate(this, delay, period, TimeUnit.MILLISECONDS);
        try {
            future.get();
        } catch (InterruptedException e) {
            Throwable cause = e.getCause();
            //发送邮件
            MailUtils.send("Write Data To HBase Faild", cause.getMessage());
        } catch (ExecutionException e) {
            Throwable cause = e.getCause();
            //发送邮件
            MailUtils.send("Write Data To HBase Faild", cause.getMessage());
        }

exception example：

public class Playground {

    /**
     * @param args
     */
    public static void main(String[] args) {
        startThread();
    }

    private static void startThread() {
        ScheduledExecutorService timer = Executors
                .newSingleThreadScheduledExecutor();
        Runnable r = new Runnable() {
            int dummyInt = 0;
            boolean dummyBoolean = false;

            @Override
            public void run() {
                dummyInt = Integer.parseInt("AAAA");

                if (dummyBoolean) {
                    dummyBoolean= false;
                } else {
                    dummyBoolean= true;
                }

            }

        };

        timer.scheduleAtFixedRate(r, 0, 100, TimeUnit.MILLISECONDS);

    }

How can I get it to?

I would expect to see this:

java.lang.NumberFormatException: For input string: "AAAA"
    at java.lang.NumberFormatException.forInputString(Unknown Source)
    at java.lang.Integer.parseInt(Unknown Source)
    at java.lang.Integer.parseInt(Unknown Source)
    at Playground$1.run(Playground.java:25)
    at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source)
    at java.util.concurrent.FutureTask$Sync.innerRunAndReset(Unknown Source)
    at java.util.concurrent.FutureTask.runAndReset(Unknown Source)
    at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$101(Unknown Source)
    at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.runPeriodic(Unknown Source)

    at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(Unknown Source)
    at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source)
    at java.lang.Thread.run(Unknown Source)

The executor probably sets its own uncaught exception handler on the thread, so the stack trace won't be printed to the console. If an exception is thrown in the Runnable you can get it from theScheduledFuture object returned by the scheduleAtFixedRate method:

ScheduledFuture<?> future = timer.scheduleAtFixedRate(r, 0, 100, TimeUnit.MILLISECONDS);
try {
    future.get();
} catch (ExecutionException e) {
    Throwable cause = e.getCause();
    cause.printStackTrace();
}
