演员外的Akka记录 [英] Akka Logging outside Actor

问题描述

我有一个Akka演员打给MyObject.foo(). MyObject不是演员.如何设置登录?使用Actor很简单，因为我可以混入ActorLogging.在MyObject中，我无权访问context.system.是否要使用AkkaSystem()创建akka.event.Logging，然后隐式创建LogSource呢?

I have an Akka Actor that makes a call to MyObject.foo(). MyObject is not an Actor. How do I setup Logging in it? With an Actor it's simple, because I can just mixin ActorLogging. In MyObject, I don't have access to context.system. Do I create an akka.event.Logging with AkkaSystem() and then what for the LogSource implicit?

推荐答案

实际上，我会将Akka日志重定向到

Actually I would redirect Akka logging to slf4j and use this API directly in all unrelated classes. First add this to your configuration:

akka {
    event-handlers = ["akka.event.slf4j.Slf4jEventHandler"]
    loglevel = "DEBUG"
}

然后选择一些SLF4J实现，我建议logback .在您的演员中继续使用ActorLogging特征.在其他类中，仅依赖于SLF4J API-甚至更好-可以尝试围绕SLF4J的 slf4s 外观.

Then choose some SLF4J implementation, I suggest logback. In your actors continue using ActorLogging trait. In other classes simply rely on SLF4J API - or even better - try out slf4s facade around SLF4J.

提示:在Logback中尝试以下记录模式:

Tip: try out the following logging pattern in Logback:

<pattern>%d{HH:mm:ss.SSS} | %-5level | %thread | %X{akkaSource} | %logger{1} | %m%n%rEx</pattern>

%X{akkaSource}将在可用时打印actor路径(就像标准日志记录一样).

The %X{akkaSource} will print actor path when available (just like standard logging).
