如何在Java中使用超时调用某些阻塞方法？

您可以使用执行器：

ExecutorService executor = Executors.newCachedThreadPool();Callable<Object> task = new Callable<Object>() {   public Object call() {      return something.blockingMethod();   }};Future<Object> future = executor.submit(task);try {   Object result = future.get(5, TimeUnit.SECONDS); } catch (TimeoutException ex) {   // handle the timeout} catch (InterruptedException e) {   // handle the interrupts} catch (ExecutionException e) {   // handle other exceptions} finally {   future.cancel(true); // may or may not desire this}

如果

future.get

TimeoutException

TimeUnit
