这个行为的解释就在afterExecute的javadoc中:

注意:当动作被包含在 task(例如FutureTask) 显式地或通过方法 提交时，这些任务对象会捕获和 维护计算性异常和 所以它们不会引起突然性 终止，和内部 异常不会传递给this 方法。

我使用的是jcabi-log中的VerboseRunnable类，它吸收所有异常并记录它们。非常方便，例如:

import com.jcabi.log.VerboseRunnable;
scheduler.scheduleWithFixedDelay(
  new VerboseRunnable(
    Runnable() {
      public void run() { 
        // the code, which may throw
      }
    },
    true // it means that all exceptions will be swallowed and logged
  ),
  1, 1, TimeUnit.MILLISECONDS
);

这与mmm的解决方案类似，但更容易理解。让你的任务扩展一个封装run()方法的抽象类。

public abstract Task implements Runnable {

    public abstract void execute();

    public void run() {
      try {
        execute();
      } catch (Throwable t) {
        // handle it  
      }
    }
}


public MySampleTask extends Task {
    public void execute() {
        // heavy, error-prone code here
    }
}

另一个解决方案是使用ManagedTask和ManagedTaskListener。

你需要一个Callable或Runnable来实现ManagedTask接口。

方法getManagedTaskListener返回你想要的实例。

public ManagedTaskListener getManagedTaskListener() {

你在ManagedTaskListener中实现了taskDone方法:

@Override
public void taskDone(Future<?> future, ManagedExecutorService executor, Object task, Throwable exception) {
    if (exception != null) {
        LOGGER.log(Level.SEVERE, exception.getMessage());
    }
}

这是

它来源于SingleThreadExecutor，但是你可以很容易地适应它 Java 8的lamdas代码，但是很容易修复

它会创建一个Executor单线程，可以得到很多任务;并将等待当前的一个结束执行，然后开始执行下一个

如果出现uncaugth错误或异常，uncaughtExceptionHandler将捕获它

public final class SingleThreadExecutorWithExceptions {

    public static ExecutorService newSingleThreadExecutorWithExceptions(final Thread.UncaughtExceptionHandler uncaughtExceptionHandler) {

        ThreadFactory factory = (Runnable runnable)  -> {
            final Thread newThread = new Thread(runnable, "SingleThreadExecutorWithExceptions");

                uncaughtExceptionHandler.uncaughtException(caugthThread, throwable);
            });

如果希望监视任务的执行，可以旋转1或2个线程(可能更多，这取决于负载)，并使用它们从ExecutionCompletionService包装器中获取任务。
