我已完成以下步骤尝试为我的Akka应用程序配置日志记录:

I have done the following steps to try and configure logging for my akka application:

创建了一个application.conf文件，并将其放在src/main/resources中.看起来像:

created an application.conf file and placed it in src/main/resources. It looks like:

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

创建了一个logback.xml文件并将其放置在src/main/resources中.看起来像:

created a logback.xml file and placed it in src/main/resources. It looks like:

<configuration> <appender name="FILE" class="ch.qos.logback.core.fileappender"> <File>./logs/akka.log</File> <encoder> <pattern>%d{HH:mm:ss.SSS} [%-5level] %msg%n</pattern> </encoder> </appender> <root level="info"> <appender-ref ref="FILE" /> </root> </configuration>

在我的.scala sbt构建文件中添加了以下内容:

added the following to my .scala sbt build file:

libraryDependencies += "com.typesafe.akka" % "akka-slf4j" % "2.0.3", libraryDependencies += "ch.qos.logback" % "logback-classic" % "1.0.9" lazy val logback = "ch.qos.logback" % "logback-classic" % "1.0.9"

尝试使用此代码进行记录:

attempted this code to log:

import akka.event.Logging val log = Logging(context.system, this) log.info("...")

我得到的只是标准输出日志记录，没有使用日志创建日志文件.

All I am getting is standard output logging, no log file creation with the logs.

我错过了一步吗?还是配置错误?

Have I missed a step ? Or misconfigured something?

推荐答案

通过这种安排，我可以使用akka.event.Logging，无需指定SLF4J实例.

With this arrangement I can use an akka.event.Logging, no need to specify SLF4J instance.

(tested 13 Dec 2013)

我得到控制台日志并记录到文件. 为了证明这不是内置记录器，我更改为包括％X {akkaTimestamp}，如下所述:

I get console logging and logging to a file. To prove this is not built-in logger I changed to include %X{akkaTimestamp} as explained here:

doc.akka.io/docs/akka/snapshot/scala/logging.html

build.sbt

library dependencies: (Akka version 2.2.3) ... "com.typesafe.akka" %% "akka-slf4j" % "2.2.3" "ch.qos.logback" % "logback-classic" % "1.0.9" ...

src/main/resources/application.conf

akka { loggers = ["akka.event.slf4j.Slf4jLogger"] loglevel = "INFO" }

src/main/resources/logback.xml

<?xml version="1.0" encoding="UTF-8"?> <configuration> <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender"> <target>System.out</target> <encoder> <pattern>%X{akkaTimestamp} %-5level[%thread] %logger{0} - %msg%n</pattern> </encoder> </appender> <appender name="FILE" class="ch.qos.logback.core.FileAppender"> <file>log/akka.log</file> <append>false</append> <encoder> <pattern>%date{yyyy-MM-dd} %X{akkaTimestamp} %-5level[%thread] %logger{1} - %msg%n</pattern> </encoder> </appender> <logger name="akka" level="INFO" /> <root level="DEBUG"> <appender-ref ref="CONSOLE"/> <appender-ref ref="FILE"/> </root> </configuration>

当我使用ActorLogging混合并直接创建Logging时，这种安排有效:

This arrangement works when I use an ActorLogging mixin and also create a Logging directly:

import akka.event.Logging val log = Logging(context.system, classOf[NameOfYourActor]) log.info("good luck!")
