为什么我的Akka日志无法在游戏中运行 [英] Why isn't my akka logging working inside of play

问题描述

我的播放代码中的日志记录工作正常，但是我所拥有的akka​​代码未记录到文件/标准输出中.

My logging is working fine from within my play code, but the akka code I have isn't logging to file/stdout.

class EmailActor extends Actor with ActorLogging {
  import EmailActor._

  log.info("email actor hatched..")
...
}

创建此actor时，在日志文件或stdout中都看不到日志记录条目.

When I create this actor I don't see the logging entries in either the log file or stdout.

我具有此激活器模板的默认application.conf: https://github.com/playframework/play-scala/blob/master/conf/logback.xml

I have the default application.conf from this activator template: https://github.com/playframework/play-scala/blob/master/conf/logback.xml

我是否需要使用akka标签修改登录文件?

Do I need to modify my logback file with some akka label?

更新

我现在在我的application.conf中完成了此操作:

I have done this now in my application.conf:

akka {
  loggers = ["akka.event.slf4j.Slf4jLogger"]
  #loggers = ["akka.event.Logging$DefaultLogger"]

  loglevel = "DEBUG"
  logging-filter = "akka.event.slf4j.Slf4jLoggingFilter"

  actor {
    debug {
      lifecycle = on
    }
  }
}

在我的依赖项中，我已经添加了这个(并且都添加到了我的play应用的dep中):

In my dependencies I have added this (and are both added to my play app's dep):

val akkaSlf4j = "com.typesafe.akka" %% "akka-slf4j" % Version.akkaSlf4j
val logback = "ch.qos.logback" % "logback-classic" % Version.logback

我的logback.xml看起来像:

My logback.xml looks like:

<!-- https://www.playframework.com/documentation/latest/SettingsLogger -->
<configuration>

  <conversionRule conversionWord="coloredLevel" converterClass="play.api.libs.logback.ColoredLevel" />

  <appender name="FILE" class="ch.qos.logback.core.FileAppender">
    <file>${application.home:-.}/logs/application.log</file>
    <encoder>
      <pattern>%date [%level] from %logger in %thread - %message%n%xException</pattern>
    </encoder>
  </appender>

  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
      <pattern>%coloredLevel %logger{15} - %message%n%xException{10}</pattern>
    </encoder>
  </appender>

  <appender name="ASYNCFILE" class="ch.qos.logback.classic.AsyncAppender">
    <appender-ref ref="FILE" />
  </appender>

  <appender name="ASYNCSTDOUT" class="ch.qos.logback.classic.AsyncAppender">
    <appender-ref ref="STDOUT" />
  </appender>

  <logger name="play" level="INFO" />
  <logger name="application" level="DEBUG" />

  <!-- Off these ones as they are annoying, and anyway we manage configuration ourselves -->
  <logger name="com.avaje.ebean.config.PropertyMapLoader" level="OFF" />
  <logger name="com.avaje.ebeaninternal.server.core.XmlConfigLoader" level="OFF" />
  <logger name="com.avaje.ebeaninternal.server.lib.BackgroundThread" level="OFF" />
  <logger name="com.gargoylesoftware.htmlunit.javascript" level="OFF" />

  <root level="WARN">
    <appender-ref ref="ASYNCFILE" />
    <appender-ref ref="ASYNCSTDOUT" />
  </root>

</configuration>

我没有在STDOUT或使用ActorLogging日志方法创建的日志文件中看到任何与akka相关的日志.

I do not see any akka related logs in STDOUT or in my log files that I create using the ActorLogging log method.

推荐答案

请注意您的logback.xml如何包含这一行，

Notice how your logback.xml has this line,

<logger name="play" level="INFO" />

允许loger_name等于播放"的记录器以INFO级别记录.

which allows a logger with loger_name equal to "play" to log at INFO level.

类似地，您需要将以下内容添加到logback.xml中，

Similarly, you will need to add the following to your logback.xml,

<logger name="akka.event.slf4j.Slf4jLogger" level="DEBUG" />
