orTimeout() 和 completeOnTimeOut() 方法都在 CompletableFuture 类中定义,这两个方法是Java 9 中引入。orTimeout() 方法可用于指定如果给定任务在特定时间内未完成,则程序停止执行并抛出 TimeoutException strong>而completeOnTimeOut()方法使用提供的值完成CompletableFuture。如果没有,它会在给定超时之前完成。
<strong>public CompletableFuture<T> orTimeout(long timeout, TimeUnit unit)</strong>
import java.util.concurrent.CompletableFuture; import java.util.concurrent.TimeUnit; public class OrTimeoutMethodTest { public static void main(String args[]) throws InterruptedException { int a = 10; int b = 15; <strong>CompletableFuture</strong>.supplyAsync(() -> { try { TimeUnit.SECONDS.sleep(5); } catch(InterruptedException e) { e.printStackTrace(); } return a + b; }) .<strong>orTimeout</strong>(4, TimeUnit.SECONDS) .<strong>whenComplete</strong>((result, exception) -> { System.out.println(result); if(exception != null) exception.printStackTrace(); }); TimeUnit.SECONDS.sleep(10); } }

<strong>public CompletableFuture<T> completeOnTimeout(T value, long timeout, TimeUnit unit)</strong>
import java.util.concurrent.CompletableFuture; import java.util.concurrent.TimeUnit; public class CompleteOnTimeOutMethodTest { public static void main(String args[]) throws InterruptedException { int a = 10; int b = 15; <strong>CompletableFuture</strong>.supplyAsync(() -> { try { TimeUnit.SECONDS.sleep(5); } catch(InterruptedException e) { e.printStackTrace(); } return a + b; }) .<strong>completeOnTimeout</strong>(0, 4, TimeUnit.SECONDS) .<strong>thenAccept</strong>(result -> System.out.println(result)); TimeUnit.SECONDS.sleep(10); } }
