你可以使用CompletionService在期货准备就绪时立即接收它们，如果其中之一引发异常，则取消处理。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;
}
}
