如何正常停止必须部署的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

我刚用akka-http创建了我的第一个rest服务器。问题是我不知道如何以可以正常关闭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 ，您可以在其中使用Akka的微内核，但已弃用。我尝试使用sbt-native-package，但是我不知道如何正常关闭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

您可以添加关闭挂钩：

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