In this article "CompletableFuture for Asynchronous Programming in Java 8", José Paumard describes several elegant patterns that enable you to chain and compose tasks in a very rich way, as well as control which thread executes each task. To see examples of how to use CompletionStage and Compl...
在这种情况下,你可以使用一个类似的工厂方法anyOf。该方法接收一个CompletableFuture对象构成的数组,返回由第一个执行完毕的CompletableFuture对象的返回值构成的CompletableFuture<Object>。

的确,使用 static 辅助方法:复制代码 代码如下 : static CompletableFutureVoid allOf(CompletableFuture?. cfs) static CompletableFutureObject anyOf(CompletableFuture?. cfs) allOf() 当所有的潜在 futures 完成时,使用了一个 futures 数组并且返回一个 future (等待所 有的障碍)。另一方面 anyOf()将会等待最快...
CompletableFuture<Object> future1 = CompletableFuture.supplyAsync(() -> { System.out.println("任务1线程:" + Thread.currentThread().getId()); int i = 10 / 2; try { Thread.sleep(3000); System.out.println("任务1运行结果:" + i); ...
