Question

我有一个sbt / scala项目，其中包含依赖项“ch.qos.logback”％“logback-classic”％“1.0.13”，并包含一个logback.xml文件，其内容如下：

<configuration debug="true">
    <logger name="com.typesafe.sslconfig.ssl.ConfigSSLContextBuilder" level="ERROR"/>
    <logger name="com.typesafe.sslconfig.ssl.AlgorithmChecker" level="ERROR"/>

    <root level="ERROR">
        <appender class="ch.qos.logback.core.ConsoleAppender">
            <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
                <pattern>%d{ISO8601} | %-5level | %thread | %logger{1} | %m%n</pattern>
            </encoder>
        </appender>
    </root>
</configuration>

当我运行程序时，我得到输出：

两个问题：

1）为什么在logback之前出现了java日志记录输出？如何确保首先初始化logback？

2）为什么记录com.typesafe.sslconfig.ssl.ConfigSSLContextBuilder中的所有警告，当我明确设置这些警告的级别为ERROR时？

我启用了logback配置调试，以便您可以看到logback确实声称将此类的loglevel设置为ERROR。但仍会记录消息。

Answer 1

root-tag中允许的唯一标记是appender-ref，您可以通过名称[1]引用先前定义的appender。将appender定义移动到配置的开头，并仅在根目录中引用它。此外，如果您对logback配置的理解是基本的，那么您应该首先阅读手册[2]。

Answer 2

问题结果是事实（我仍然不明白为什么会这样），以下akka配置逻辑：

akka {
  loglevel = "ERROR"
  stdout-loglevel = "ERROR"
  loggers = ["akka.event.slf4j.Slf4jLogger"]
}

包含在CLI实用程序使用的库中的reference.conf中，需要添加到CLI JAR中尚未存在的application.conf中。虽然我不明白为什么这是必要的，但它导致问题消失。我原以为在库中包含一个reference.conf，如果没有被库的调用者中的相应配置覆盖，仍然会生效。显然，我错了。

logback忽略了我的logback.xml
