这就是我用来在未来列表上等待特定时间的方法。我认为它更干净。

CountDownLatch countDownLatch = new CountDownLatch(partitions.size());
// Some parallel work
        for (Something tp : somethings) {
            completionService.submit(() -> {
                try {
                   work(something)
                } catch (ConnectException e) {
                } finally {
                    countDownLatch.countDown();
                }
            });
        }    
  try {
        if (!countDownLatch.await(secondsToWait, TimeUnit.SECONDS)){
        }
    } catch (InterruptedException e) {
    }

 /**
     * execute suppliers as future tasks then wait / join for getting results
     * @param functors a supplier(s) to execute
     * @return a list of results
     */
    private List getResultsInFuture(Supplier<?>... functors) {
        CompletableFuture[] futures = stream(functors)
                .map(CompletableFuture::supplyAsync)
                .collect(Collectors.toList())
                .toArray(new CompletableFuture[functors.length]);
        CompletableFuture.allOf(futures).join();
        return stream(futures).map(a-> {
            try {
                return a.get();
            } catch (InterruptedException | ExecutionException e) {
                //logger.error("an error occurred during runtime execution a function",e);
                return null;
            }
        }).collect(Collectors.toList());
    };

也许这会有帮助(没有什么会被原始的线取代，耶!) 我建议用一个分开的线程运行每个Future家伙(它们并行)，然后当其中一个得到错误时，它只是信号管理器(Handler类)。

class Handler{
//...
private Thread thisThread;
private boolean failed=false;
private Thread[] trds;
public void waitFor(){
  thisThread=Thread.currentThread();
  List<Future<Object>> futures = getFutures();
  trds=new Thread[futures.size()];
  for (int i = 0; i < trds.length; i++) {
    RunTask rt=new RunTask(futures.get(i), this);
    trds[i]=new Thread(rt);
  }
  synchronized (this) {
    for(Thread tx:trds){
      tx.start();
    }  
  }
  for(Thread tx:trds){
    try {tx.join();
    } catch (InterruptedException e) {
      System.out.println("Job failed!");break;
    }
  }if(!failed){System.out.println("Job Done");}
}

private List<Future<Object>> getFutures() {
  return null;
}

public synchronized void cancelOther(){if(failed){return;}
  failed=true;
  for(Thread tx:trds){
    tx.stop();//Deprecated but works here like a boss
  }thisThread.interrupt();
}
//...
}
class RunTask implements Runnable{
private Future f;private Handler h;
public RunTask(Future f,Handler h){this.f=f;this.h=h;}
public void run(){
try{
f.get();//beware about state of working, the stop() method throws ThreadDeath Error at any thread state (unless it blocked by some operation)
}catch(Exception e){System.out.println("Error, stopping other guys...");h.cancelOther();}
catch(Throwable t){System.out.println("Oops, some other guy has stopped working...");}
}
}

我不得不说上面的代码会出错(没有检查)，但我希望我可以解释解决方案。请试一试。

基于guava的解决方案可以使用Futures.FutureCombiner实现。

下面是在javadoc中给出的代码示例:

 final ListenableFuture<Instant> loginDateFuture =
     loginService.findLastLoginDate(username);
 final ListenableFuture<List<String>> recentCommandsFuture =
     recentCommandsService.findRecentCommands(username);
 ListenableFuture<UsageHistory> usageFuture =
     Futures.whenAllSucceed(loginDateFuture, recentCommandsFuture)
         .call(
             () ->
                 new UsageHistory(
                     username,
                     Futures.getDone(loginDateFuture),
                     Futures.getDone(recentCommandsFuture)),
             executor);

要了解更多信息，请参阅用户指南的ListenableFutureExplained部分。

如果您对它的工作原理感到好奇，我建议查看源代码的这一部分:aggregatefuture .java#L127-L186

在Java 8中使用CompletableFuture

    // Kick of multiple, asynchronous lookups
    CompletableFuture<User> page1 = gitHubLookupService.findUser("Test1");
    CompletableFuture<User> page2 = gitHubLookupService.findUser("Test2");
    CompletableFuture<User> page3 = gitHubLookupService.findUser("Test3");

    // Wait until they are all done
    CompletableFuture.allOf(page1,page2,page3).join();

    logger.info("--> " + page1.get());

您可以使用CompletionService在期货准备就绪时接收它们，如果其中一个抛出异常，则取消处理。就像这样:

Executor executor = Executors.newFixedThreadPool(4);
CompletionService<SomeResult> completionService = 
       new ExecutorCompletionService<SomeResult>(executor);

//4 tasks
for(int i = 0; i < 4; i++) {
   completionService.submit(new Callable<SomeResult>() {
       public SomeResult call() {
           ...
           return result;
       }
   });
}

int received = 0;
boolean errors = false;

while(received < 4 && !errors) {
      Future<SomeResult> resultFuture = completionService.take(); //blocks if none available
      try {
         SomeResult result = resultFuture.get();
         received ++;
         ... // do something with the result
      }
      catch(Exception e) {
             //log
         errors = true;
      }
}

我认为您可以进一步改进，取消任何仍在执行的任务，如果其中一个抛出错误。
