将Scala Future转变为CompletableFuture [英] Transform Scala Future into CompletableFuture

问题描述

在我的项目中，我有一个Akka层，该层返回一个Scala Future，并且接收到Future的部分是Java味道.

I have in my project an Akka layer which returns a Scala Future, and the part that receives that Future is Java flavour.

团队中的人们并不了解Scala，他们宁愿使用CompletableFuture，因为他们更了解Java 8 API.

People in the team don't know Scala and they would rather use CompletableFuture since they know the Java 8 API much better.

有什么好方法可以将Scala future转换为CompletableFuture吗?

Is there any good way to transform a Scala future into a CompletableFuture?.

显然是一种非阻塞方式.

Obviously in a non-blocking way.

致谢.

推荐答案

使用 scala-java8-兼容库:

import java.util.concurrent.CompletableFuture
import scala.concurrent.Future
import scala.compat.java8.FutureConverters._

val scalaFuture = Future.apply("Hello")
val javaFuture: CompletableFuture[String] = scalaFuture.toJava.toCompletableFuture
