Question

我通过扩展AbstractLoggingActor实现了actor。但不知何故，akka日志只被写入控制台而不是日志文件，并且不会抛出任何错误。

我在akka中尝试了各种配置，使用与实际akka版本相同版本的akka-slf4j但没有帮助。我附加了我最初使用的原始pom配置。

logback.xml

<appender name="fileAppender" class="ch.qos.logback.core.FileAppender">
    <file>/opt/Corp-Async-Job-Processor/logs/corp-job-akka-framework.log</file>
    <append>true</append>
    <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
        <level>info</level>
    </filter>
    <encoder>
        <pattern>%date{ISO8601} - %logger -> %-5level[%thread] %logger{0} - %msg%n</pattern>
    </encoder>
</appender>
<!--appender name="Sentry" class="io.sentry.logback.SentryAppender">
    <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
        <level>INFO</level>
    </filter>
</appender-->
<appender name="console" class="ch.qos.logback.core.ConsoleAppender">
    <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
        <level>debug</level>
    </filter>
    <encoder>
        <pattern>%date{ISO8601} - %logger -> %-5level[%thread] %logger{0} - %msg%n</pattern>
    </encoder>
</appender>

<logger name="akka" level="debug" />
<logger name="com.packt" level="debug"/>

<root level="TRACE">
    <appender-ref ref="fileAppender"/>
    <appender-ref ref="console"/>

</root>

application.conf：

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

Answer 1

Logback的ThresholdFilter拒绝级别低于配置阈值的事件。您的FileAppender具有以下过滤条件：

<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
    <level>info</level>
</filter>

以上配置意味着TRACE和DEBUG事件被拒绝。相反，您的ConsoleAppender的{{1}}设置为DEBUG，仅拒绝TRACE事件。因为您的Akka日志级别设置为DEBUG，所以Akka日志消息会将其发送到控制台，但永远不会将其发送到日志文件。

要将Akka日志输出到控制台和文件，请更改ThresholdFilter中过滤器的阈值：

FileAppender

AbstractLoggingActor不写入File Appender，而是写入Java Akka中的控制台
