播放应用中的ActorSystem费用

Question

I have a question , is it expansive for productivity, do ActorSystem system = ActorSystem.create("System"); many times, or I must do this once and use one reference ?

Answer 1

You should create only one ActorSystem , from the Akka doc :

An ActorSystem is a heavyweight structure that will allocate 1…N Threads, so create one per logical application
