如何优雅地停止必须部署的 akka-http 服务器的 actor 系统. [英] How to stop gracefully the actor system for an akka-http server that must be deployed.

问题描述

我刚刚用 akka-http 创建了我的第一个休息服务器.问题是我不知道如何以一种可以优雅地关闭 actor 系统的方式部署服务器.

I just created my first rest server with akka-http. The problem is that I do not know how to deploy the server in such a way that I could gracefully shutdown the actor system.

例如，我在这里找到了一些东西:https://stackoverflow.com/a/17399574/5388513 你可以在哪里使用 Akka 的微内核，但它已被弃用.我尝试使用 sbt-native-package，但我不知道如何优雅地关闭 actor 系统.

For example I found something here: https://stackoverflow.com/a/17399574/5388513 where you could use Akka's microkernel, but it is deprecated. I tried using sbt-native-package, but I do not know how to gracefully shutdown the actor system.

谢谢！

推荐答案

可以添加关机钩子:

// import scala.concurrent.duration._
//shutdown Hook
scala.sys.addShutdownHook {
  logger.info("Terminating...")
  actorSystem.terminate()
  Await.result(actorSystem.whenTerminated, 30 seconds)
  logger.info("Terminated... Bye")
}
