相关疑难解决方法(0)

我检查了Oracle Java API,它给出了FutureTask.isDone()的一些信息.

但我需要检查任务是否已完成或因任何错误而终止.isDone()方法即使完成/终止也会返回.但我需要知道它是否由于某些问题而完成或终止.

我创建了以下FutureTask方法来异步运行方法.

public FutureTask<Object> SendAggregateEventAsync(final
        com.Company.Product.SDK.Device.AggregateEvent.ClassObject 
        request)
{
    FutureTask<Object> futureTask;

    futureTask = new FutureTask<Object>(new Runnable() {
        public void run()
        {
            try {
                SendAggregateEvent(request);
            } catch (ResponseException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }, null);

    return futureTask;
}

public void SendAggregateEvent(
        com.Company.Product.SDK.Device.AggregateEvent.ClassObject 
        request) throws ResponseException
{
    try 
    {
        if(request == null) throw new IllegalArgumentException("request");

        String[] s_array = new String[0];
        s_array[0] = "EventTime";

        String namespace = "http://Product.Company.com/" +
                "v1.0/Device/AggregateEvent";

        IBindingFactory factory;

        factory = BindingDirectory.getFactory(
                com.Compant.Product.SDK.Device.AggregateEvent.
                ClassObject.class);

        String message = …
