Scala Akka记录模式不可更改

我正在为我的学士学位论文构建一个小的actor应用程序，现在我正在尝试添加一些日志记录

对于actorsystem内部的日志记录，我想使用akka在后台提供的logback classic日志记录。 到目前为止，日志记录工作正常，但是当我在logback.xml中更改它时，actor系统内部的模式没有改变

有人知道如何通过slf4j和actorsystem内部的日志记录来改变全局模式吗

参与者系统外的日志输出：

问题是akka加载的是默认配置，而不是自定义配置。要解决此问题，必须更改配置的加载：

导入akka.event.Logging 导入com.typesafe.config.ConfigFactory

object SimulationMaster extends App{
   val system = ActorSystem("EBTreeSimulation", ConfigFactory.load)
   val log = Logging.getLogger(system,this)
   ....
}

---

多亏了cmbaxter

其他答案有效地回答了这个问题。然而，我有几个其他相关的问题

要帮助调试此问题，可以按如下方式记录ActorSystem配置：

object SimulationMaster extends App{
   val conf = ConfigFactory.load
   val system = ActorSystem("EBTreeSimulation", conf)
   val log = Logging.getLogger(system,this)
   log info conf.getObject("akka").toString
   ....
}

---

在这个输出中，我看到，

akka.loggers

仍然被设置为一些默认记录器，而不是slf4j记录器。进一步查看配置，我发现设置了slf4j记录器，但它设置为单数

akka.logger

。我对它进行了多重化，然后一切都开始工作。

我认为您的问题可能与这一行有关

ConfigFactory.load.getConfig（“akka”）

。尝试将其更改为仅

ConfigFactory.load

。这样它就可以看到子元素“akka”并从中获得修改后的日志配置。很好，解决了这个问题！谢谢
