Question

为我的学士论文建立一个小型演员应用程序，现在我正在尝试添加一些日志记录。

为了在actorsystem内部进行日志记录，我想在后台使用log akka提供的logback-classic。到目前为止，日志记录运行良好，但是当我在logback.xml中更改它时，actor系统内的模式不会改变

任何人都知道如何更改全局模式并通过slf4j进行日志记录并在actorsystem中记录？

在演员系统外部记录输出：

2014-07-11 13:03:09 INFO  model.AccessLayer : New Object 10 with id:188586187441591506  `
2014-07-11 13:03:09 INFO  model.AccessLayer : New Object 11 with id:188586187442115794`

来自actor系统内部的日志输出：

[INFO] [07/11/2014 13:03:09.199] [EBTreeSimulation-akka.actor.default-dispatcher-4] [akka://EBTreeSimulation/user/nodeA] nodeA[InsertNewObject] received new object:188586187441591506, 188586187441591506, 10 

[INFO] [07/11/2014 13:03:09.199] [EBTreeSimulation-akka.actor.default-dispatcher-3] [akka://EBTreeSimulation/user/nodeB] nodeB[InsertNewObject] received new object:188586187441591506, 188586187441591506, 10

slf4j的记录器初始化：

import org.slf4j.LoggerFactory

class AccessLayer[T](communicationLayer:ActorRef, actors:List[ActorRef]) {
  val log = LoggerFactory.getLogger(classOf[AccessLayer[T]])
  ....
}

actorSystem的记录器初始化：

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

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

import akka.event.Logging

class TreeActor[T](communication:ActorRef) extends Actor {
   val log = Logging(context.system,this)
   ....

}

logback.xml：

<configuration>
<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <File>./logs/myLog.log</File>
    <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
        <fileNamePattern>logs/myLog.%i.log.zip</fileNamePattern>
        <minIndex>1</minIndex>
        <maxIndex>3</maxIndex>
    </rollingPolicy>
    <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
        <maxFileSize>5MB</maxFileSize>
    </triggeringPolicy>
    <encoder>
        <pattern>%date{YYYY-MM-dd HH:mm:ss} %level %X{sourceThread} %logger{10} [%file:%line]: %msg%n</pattern>
    </encoder>
</appender>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <!--<target>System.out</target>-->
    <encoder>
        <pattern>%date{YYYY-MM-dd HH:mm:ss} %-5level %logger : %msg%n</pattern>
    </encoder>
</appender>
<!--<logger name="akka" level="INFO" />-->
<root level="info">
    <appender-ref ref="FILE"/>
    <appender-ref ref="STDOUT" />
</root>

application.conf：

akka {
    # Loggers to register at boot time (akka.event.Logging$DefaultLogger logs
    # to STDOUT)
    loggers = ["akka.event.slf4j.Slf4jLogger"]
    #event-handlers = ["akka.event.slf4j.Slf4jEventHandler"]

    loglevel = "INFO"   
    stdout-loglevel = "DEBUG"
    actor {
       provider = "akka.cluster.ClusterActorRefProvider"
        default-dispatcher {
            throughput = 10
        }
    }
    remote {
        netty.tcp.port = 4711
    }
}

Answer 1

问题是akka加载默认配置而不是自定义配置。要解决问题，必须更改配置的加载：

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

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

Answer 2

其他答案已经有效地回答了这个问题。但是，我还有其他一些相关问题。

为了帮助调试问题，您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
   ....
}

在此输出中，我看到akka.loggers仍设置为某个默认记录器而不是slf4j记录器。进一步查看配置，我发现slf4j记录器已设置，但设置为单数 akka.logger。我把它复数，然后一切都开始工作了。

Akka日志模式不变
