无论当前 CompletableFuture 正常完成还是因异常未能完成,都会应用给定的 BiFunction 处理结果或异常,并返回一个新的 CompletableFuture。 4. 其他重要方法 a. allOf(CompletableFuture<?>... cfs) 创建一个新的 CompletableFuture,当所有给定的 CompletableFuture 都完成(不论成功与否)时,新 CompletableFuture 完成。

Completable:可完成Future:未来/将来 这两个单词体现了它设计的目的:提供一种可完成的异步计算。身世 接下来我将详细介绍CompletableFuture的实现。Future接口 CompletableFuture实现自JDK 5出现的Future接口,该接口属于java.util.concurrent包,这个包提供了用于并发编程的一些基础设施,其中就包括 Future 接口。Future接口...

可以通过静态方法CompletableFuture.supplyAsync()创建一个异步任务。以下是一个基本的示例: package cn.juwatech.completablefuture; import java.util.concurrent.CompletableFuture; import java.util.concurrent.ExecutionException; public class BasicUsage {
