在我的Play-Scala应用程序中,log.info("...")
命令被忽略。
我已经咨询了以下内容:
Akka actor logging not writing to file
Play Akka logger doesn't output debug messages to console
我的application.conf
文件的相关内容是:
akka {
loggers = ["akka.event.slf4j.Slf4jLogger"]
loglevel = "INFO"
log-config-on-start = on
}
...
和logback.xml
:
<configuration>
<conversionRule conversionWord="coloredLevel" converterClass="play.api.libs.logback.ColoredLevel" />
<appender name="FILE" class="ch.qos.logback.core.FileAppender">
<file>/var/log/foo/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="INFO" />
<logger name="akka" level="INFO" />
<!-- 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>
在我的代码中,我有类似的东西:
class MyActor extends Actor with ActorLogging {
override def receive = {
case msg =>
println("This should show up in the console")
log.info("log this message", msg)
}
}
但是,即使终端显示了application.log
命令的输出,我的log.info
文件也不包含来自println
命令的任何消息:

如application.log
的内容所示,log-config-on-start = on
文件中的行application.conf
在工作。
如何获取log.info
命令以写入application.conf
文件?

如果将Play框架与Akka一起使用,则可以利用play框架本身提供的Logging优势。 Play框架会为您创建actor系统,您可以使用PlayLogging记录消息。
如下配置您的logback.xml文件:
<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
</appender>
<appender name="ASYNCSTDOUT" class="ch.qos.logback.classic.AsyncAppender">
<appender-ref ref="STDOUT" />
</appender>
<root level="INFO">
<appender-ref ref="ASYNCSTDOUT" />
</root>
</configuration>
然后您可以通过扩展PlayLogging特性来利用Play框架提供的日志支持。
class SampleTestActor extends Actor with PlayLogging {
def receive: Receive = {
case m: AnyEvent =>
logger.info(s"Received metric event $m")
}
}
