避免 akka 终止 webapp JVM 进程

Question

当一些意外异常发生时，如何避免 Akka 终止 JVM PROCESS？。我认为这是一个大问题。

Akka 不应该杀死我的 webapp 的 jvm 进程。

我正在使用播放框架 2.3。

用例：

Uncaught error from thread [SuperActorSystem-akka.actor.default-dispatcher-5] shutting down JVM since 'akka.jvm-exit-on-fatal-error' is enabled

谢谢。

解决方案是将以下内容添加到我的 playframework 应用程序中的 application.conf 中：

akka{  
    jvm-exit-on-fatal-error = off
}

这就是我可以在 play 应用程序中覆盖 akka 默认参数的方式。谢谢大家。
