scala - 我的 logback.xml 和 Akka 有什么问题？

Question

为什么我的 logback 日志被 Akka 阻塞了？如果我单独留下 Akka 配置但删除我的 logback.xml 文件，无论默认值是什么，它都可以正常工作。我的 logback.xml 文件中是否存在配置错误？

logback.xml

<configuration>
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>
    <root level="ERROR">
        <appender-ref ref="STDOUT" />
    </root>
</configuration>

应用程序.conf

akka {
    loglevel = "ERROR"
    stdout-loglevel = "ERROR"
    loggers = ["akka.event.slf4j.Slf4jLogger"]
    actor {
        provider = akka.remote.RemoteActorRefProvider
    }
    remote {
        enabled-transports = ["akka.remote.netty.tcp"]
    }
}

Build.scala(剪辑):

lazy val root = project.in(file("."))
    .settings(basicSettings: _*)
    .settings(libraryDependencies ++=
        dep_compile(
            typesafe_config, logback, akka_actor, akka_remote, akka_slf4j) ++ 
        dep_test(scalatest)
    )

当某些东西尝试记录错误时，我得到:

您在配置中使用旧的记录器类。以下是修复方法:

Akka (2.3.0) fails to load Slf4jEventHandler class with java.lang.ClassNotFoundException
