Injecting services into Scala Akka Actors with Google Guice

Question

I have a couple of services that I want to inject into akka actors. There are three different types of actors I am working with, and each type will use different services. Currently I just have a module, instantiate an injector inside of the actor, and do the binding inside of each Crow. The issue is that for each other, they receive a new instance of the service.

I did a little bit of reading and found http://www.typesafe.com/activator/template/activator-akka-scala-guice but the documentation for akka recommends we not use IndirectActorProducer. What is the best way for me to inject these services into my actors? The @Inject keyword looks promising but I'm not exactly sure how to use this.

Workflow:

Main creates commander, sends it a command, commander creates the three different types of crows, and sends them messages to execute (it is these crows that require the services).

Answer 1

在您的模块中使用@Provides方法接受服务作为参数并返回ActorRefs。在这些提供程序方法中，您从注入的服务中实例化Props，但让akka实际创建actor，因此您不需要子注入器。

我最终使用http://www.typesafe.com/activator/template/activator-akka-scala-guice作为指南。我发现它工作得很好，它实际上并没有使用IndirectActorProducer，而是另一个扩展它的类，这也是他们推荐的。
