如何配置Logback以将记录器的不同级别记录到不同的目的地？

| 如何配置Logback以将记录器的不同级别记录到不同的目的地？ 例如，给定以下Logback配置，Logback将记录
INFO
消息到
STDOUT
和
ERROR
消息到
STDERR
吗？ （请注意，此示例是示例“ 4”的变体，如第3章：Logback配置中所示）。 
<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>
  <appender name=\"STDERR\"
   class=\"ch.qos.logback.core.ConsoleAppender\">
   <encoder>
     <pattern>
        %d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n
      </pattern>
    </encoder>
    <target>System.err</target>
  </appender>
  <!-- What is the effective level of \"chapters.configuration\"? -->
  <logger name=\"chapters.configuration\" level=\"INFO\" additivity=\"false\">
    <appender-ref ref=\"STDOUT\" />
  </logger>
  <logger name=\"chapters.configuration\" level=\"ERROR\" additivity=\"false\">
    <appender-ref ref=\"STDERR\" />
  </logger>

  <!-- turn OFF all logging (children can override) -->
  <root level=\"OFF\">
    <appender-ref ref=\"STDOUT\" />
  </root>
</configuration>

    更新：有关使用Groovy的基于所有配置的方法，请参见Dean Hiller的答案。 - 您可以使用Logback过滤器做一些有趣的事情。以下配置仅将警告和错误消息打印到stderr，并将其他所有信息打印到stdout。 logback.xml 
    <appender name=\"stdout\" class=\"ch.qos.logback.core.ConsoleAppender\">
  <target>System.out</target>
  <filter class=\"com.foo.StdOutFilter\" />
   ...
</appender>

<appender name=\"stderr\" class=\"ch.qos.logback.core.ConsoleAppender\">
  <target>System.err</target>
  <filter class=\"com.foo.ErrOutFilter\" />
   ...
</appender>

<logger name=\"mylogger\" level=\"debug\">
    <appender-ref ref=\"stdout\" />
    <appender-ref ref=\"stderr\" />
</logger>
    com.foo.StdOutFilter 
    public class StdOutFilter extends ch.qos.logback.core.filter.AbstractMatcherFilter
{

    @Override
    public FilterReply decide(Object event)
    {
        if (!isStarted())
        {
            return FilterReply.NEUTRAL;
        }

        LoggingEvent loggingEvent = (LoggingEvent) event;

        List<Level> eventsToKeep = Arrays.asList(Level.TRACE, Level.DEBUG, Level.INFO);
        if (eventsToKeep.contains(loggingEvent.getLevel()))
        {
            return FilterReply.NEUTRAL;
        }
        else
        {
            return FilterReply.DENY;
        }
    }

}
    com.foo.ErrOutFilter 
    public class ErrOutFilter extends ch.qos.logback.core.filter.AbstractMatcherFilter
{

    @Override
    public FilterReply decide(Object event)
    {
        if (!isStarted())
        {
            return FilterReply.NEUTRAL;
        }

        LoggingEvent loggingEvent = (LoggingEvent) event;

        List<Level> eventsToKeep = Arrays.asList(Level.WARN, Level.ERROR);
        if (eventsToKeep.contains(loggingEvent.getLevel()))
        {
            return FilterReply.NEUTRAL;
        }
        else
        {
            return FilterReply.DENY;
        }
    }

    仅基于配置的解决方案，带有ThresoldFilter和LevelFilters使事情真正易于理解：

    最简单的解决方案是在附加器上使用
    ThresholdFilter
    ： 
        <appender name=\"...\" class=\"...\">
        <filter class=\"ch.qos.logback.classic.filter.ThresholdFilter\">
            <level>INFO</level>
        </filter>
    完整示例： 
    <configuration>
    <appender name=\"STDOUT\" class=\"ch.qos.logback.core.ConsoleAppender\">
        <filter class=\"ch.qos.logback.classic.filter.ThresholdFilter\">
            <level>INFO</level>
        </filter>
        <encoder>
            <pattern>%d %-5level: %msg%n</pattern>
        </encoder>
    </appender>

    <appender name=\"STDERR\" class=\"ch.qos.logback.core.ConsoleAppender\">
        <filter class=\"ch.qos.logback.classic.filter.ThresholdFilter\">
            <level>ERROR</level>
        </filter>
        <target>System.err</target>
        <encoder>
            <pattern>%d %-5level: %msg%n</pattern>
        </encoder>
    </appender>

    <root>
        <appender-ref ref=\"STDOUT\" />
        <appender-ref ref=\"STDERR\" />
    </root>
</configuration>
    更新：正如Mike在评论中指出的那样，此处将错误级别为ERROR的消息同时打印到STDOUT和STDERR。不过，不知道OP的意图是什么。如果这不是您想要的，可以尝试Mike的答案。

    这是我使用的配置，效果很好，它基于XML + JaninoEventEvaluator（需要将Janino库添加到Classpath中） 
    <configuration>
<appender name=\"STDOUT\" class=\"ch.qos.logback.core.ConsoleAppender\">
    <encoder>
        <pattern>%date | [%-5level] in [%file:%line] - %msg %n</pattern>
    </encoder>
    <filter class=\"ch.qos.logback.core.filter.EvaluatorFilter\">
        <evaluator class=\"ch.qos.logback.classic.boolex.JaninoEventEvaluator\">
            <expression>
                level &lt;= INFO
            </expression>
        </evaluator>
        <OnMismatch>DENY</OnMismatch>
        <OnMatch>NEUTRAL</OnMatch>
    </filter>
</appender>

    吐兄

    我使用logback.groovy来配置我的logback，但是您也可以使用xml config来做到这一点： 
    import static ch.qos.logback.classic.Level.*
import static ch.qos.logback.core.spi.FilterReply.DENY
import static ch.qos.logback.core.spi.FilterReply.NEUTRAL
import ch.qos.logback.classic.boolex.GEventEvaluator
import ch.qos.logback.classic.encoder.PatternLayoutEncoder
import ch.qos.logback.core.ConsoleAppender
import ch.qos.logback.core.filter.EvaluatorFilter

def patternExpression = \"%date{ISO8601} [%5level] %msg%n\"

appender(\"STDERR\", ConsoleAppender) {
    filter(EvaluatorFilter) {
      evaluator(GEventEvaluator) {
        expression = \'e.level.toInt() >= WARN.toInt()\'
      }
      onMatch = NEUTRAL
      onMismatch = DENY
    }
    encoder(PatternLayoutEncoder) {
      pattern = patternExpression
    }
    target = \"System.err\"
  }

appender(\"STDOUT\", ConsoleAppender) {
    filter(EvaluatorFilter) {
      evaluator(GEventEvaluator) {
        expression = \'e.level.toInt() < WARN.toInt()\'
      }
      onMismatch = DENY
      onMatch = NEUTRAL
    }
    encoder(PatternLayoutEncoder) {
      pattern = patternExpression
    }
    target = \"System.out\"
}

logger(\"org.hibernate.type\", WARN)
logger(\"org.hibernate\", WARN)
logger(\"org.springframework\", WARN)

root(INFO,[\"STDERR\",\"STDOUT\"])
    我认为使用GEventEvaluator更为简单，因为无需创建过滤器类。 我为我的英语道歉！

    尝试这个。您可以只使用内置的
    ThresholdFilter
    和
    LevelFilter
    。无需以编程方式创建自己的过滤器。在此示例中，WARN和ERROR级别记录到System.err，其余部分记录到System.out：      
    <appender name=\"stdout\" class=\"ch.qos.logback.core.ConsoleAppender\">
    <!-- deny ERROR level -->
    <filter class=\"ch.qos.logback.classic.filter.LevelFilter\">
        <level>ERROR</level>
        <onMatch>DENY</onMatch>
    </filter>
    <!-- deny WARN level -->
    <filter class=\"ch.qos.logback.classic.filter.LevelFilter\">
        <level>WARN</level>
        <onMatch>DENY</onMatch>
    </filter>
    <target>System.out</target>
    <immediateFlush>true</immediateFlush>
    <encoder>
        <charset>utf-8</charset>
        <pattern>${msg_pattern}</pattern>
    </encoder>
</appender>

<appender name=\"stderr\" class=\"ch.qos.logback.core.ConsoleAppender\">
    <!-- deny all events with a level below WARN, that is INFO, DEBUG and TRACE -->
    <filter class=\"ch.qos.logback.classic.filter.ThresholdFilter\">
        <level>WARN</level>
    </filter>
    <target>System.err</target>
    <immediateFlush>true</immediateFlush>
    <encoder>
        <charset>utf-8</charset>
        <pattern>${msg_pattern}</pattern>
    </encoder>
</appender>   

<root level=\"WARN\">
    <appender-ref ref=\"stderr\"/>
</root>

<root level=\"TRACE\">
    <appender-ref ref=\"stdout\"/>
</root>

    我对这个答案不屑一顾，因为它只是上面两个最佳答案的组合：X. Wo Satuk和SébastienHelbert：
    ThresholdFilter
    很可爱，但是您不能配置它有一个鞋面级别以及较低级别*，但将其与设置为“ DENY”，“ 22”和“ 2”的两个
    LevelFilters
    结合使用是一种享受。 非常重要：不要忘记STDERR附加程序中的
    <target>System.err</target>
    标记：几分钟的遗漏让我感到沮丧。

So here is the logback file in which I am not printing backtype.storm.metric.LoggingMetricsConsumer info level if i say additivity = \"true\" then for for all classes in backtype.* this rule will be applied

    如何将级别为“ INFO \”或更高级别的彩色消息输出到控制台，以及如何将级别为“ WARN \”或更高级别的消息输出到文件。 您的logback.xml文件： 
    <?xml version=\"1.0\" encoding=\"UTF-8\"?>

<configuration>
    <include resource=\"org/springframework/boot/logging/logback/defaults.xml\"/>
