akka、spray和log4j2记录不正确

Question

我正在Akka、Spray和Log4j2中构建一个新应用程序。我的大多数主要系统都在“hello world”类型的模式下工作，但我很难让日志正常工作，我无法判断这是log4j2问题、Akka/Spray问题还是我的迟钝问题。

首先，我的Akka配置文件

akka {
    loggers = ["akka.event.slf4j.Slf4jLogger"]
    loglevel = DEBUG
    log-config-on-start = on

    actor{
        debug {
              receive = on
              autoreceive = on
              lifecycle = on
              fsm = on
              event-stream = on
              unhandled = on
              router-misconfiguration = on
            }
    }
}

现在，如果我把loggers行注释掉，在IntelliJ中运行这个应用程序，它在控制台中是完美的。我得到我想要的一切，我得到非常详细和有用的日志，我得到配置设置，我看到交易进出，我是一个非常快乐的人。当我试图通过Log4j2管道传输它时，问题就出现了。

现在我想这样做的原因是在不远的将来，我将把所有日志泵送到Cassandra集群中进行map减少工作。

因此，我在上面的配置文件中取消了slf4j行的注释，在类路径中添加slf4j、log4j2和log4j2的log4j-slf4j-impl，log4j激活，读取配置文件，创建日志文件，将附件的初始化和调试信息记录到控制台，就这样。没有其他消息。没有一件幸运的事。娜达。

这是我的log4j2.xml档案

<?xml version="1.0" encoding="UTF-8"?>
<configuration status="DEBUG">
    <appenders>
        <Console name="CONSOLE" target="SYSTEM_OUT">
            <PatternLayout pattern="%-5p %c{2} - %m%n" />
        </Console>
        <RollingRandomAccessFile name="logFileOutput" fileName="logs/wisdomOutput.log"
                     filePattern="logs/$${date:yyyy-MM}/app-%d{MM-dd-yyyy}-%i.log.gz">
            <PatternLayout>
                <pattern>%d %p %C [%t] %m%n</pattern>
            </PatternLayout>
            <Policies>
                <TimeBasedTriggeringPolicy />
                <SizeBasedTriggeringPolicy size="50 MB"/>
            </Policies>
            <DefaultRolloverStrategy max="20"/>
        </RollingRandomAccessFile>
    </appenders>
    <loggers>
        <!-- if you want to dump different packages to different files, here's where you do it
            <logger name="com.onuspride" level="DEBUG" additivity="false">
            <appender-ref ref="logFileOutput"/>
        </logger>-->
        <root>
            <appender-ref ref="CONSOLE"/>
            <appender-ref ref="logFileOutput"/>
        </root>
    </loggers>
</configuration>

我不知道我是否在处理log4j2中的错误，或者我的配置文件是否错误，或者是什么。

这是当我的日志被激活时我的控制台输出

我想我的问题是，我不知道如何从Akka通过log4j2对标准输出进行格式化，然后写入文件。目前我真的不想再复杂了。

我的设置有什么问题？为什么不起作用？

Answer 1

一切看起来都很好，我想你只需要设置根记录器的日志级别（看起来你已经找到了）。

一件小事：在RollingFile appender PatternLayout中，您使用的是%C。我建议您改用%C（小写）。%C遍历堆栈跟踪以获取位置信息，这将导致性能更差。（log4j2手册有更多细节。）
