java - Logback忽略父包的记录器

Question

Logback 忽略父包的记录器。

我有那些附加程序:

附加器

<appender name="fileAppender1" class="ch.qos.logback.core.FileAppender">
    <file>myLogFile1.log</file>
    <encoder>
        <pattern>%d [%thread] %-5level %logger - %msg%n</pattern>
    </encoder>
</appender>
<appender name="fileAppender2" class="ch.qos.logback.core.FileAppender">
    <file>myLogFile2.log</file>
    <encoder>
        <pattern>%d [%thread] %-5level %logger - %msg%n</pattern>
    </encoder>
</appender>
<appender name="console" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
        <pattern>%d [%thread] %-5level %logger - %msg%n</pattern>
    </encoder>
</appender>

还有 3 个记录器:

记录器 1

<logger name="my" level="INFO" additivity="false" >
    <appender-ref ref="fileAppender1" />
</logger>

记录器 2

<logger name="my.test" level="DEBUG" additivity="false" >
    <appender-ref ref="console" />
</logger>

记录器3

<root level="TRACE">
    <appender-ref ref="fileAppender2" />
</root>

• 如果我使用其中三个，我只能得到第二个记录器的工作。 (最权威的)
• 如果我删除additivity="false"，所有记录器都会写入相同级别的相同信息(最高 - INFO)

如何配置日志记录，根记录器通过附加程序收集和打印所有TRACE日志消息，my记录器收集并打印包my的所有DEBUG消息，不带包my.test和my.test记录器收集并打印包my.test的所有INFO消息并向下？

使用级别过滤器

<filter class="ch.qos.logback.classic.filter.LevelFilter">
      <level>INFO</level>
      <onMatch>ACCEPT</onMatch>
      <onMismatch>DENY</onMismatch>
</filter>

因此你的 logback.xml 将变成

<appender name="fileAppender1" class="ch.qos.logback.core.FileAppender">
    <filter class="ch.qos.logback.classic.filter.LevelFilter">
          <level>INFO</level>
          <onMatch>ACCEPT</onMatch>
          <onMismatch>DENY</onMismatch>
    </filter>
    <file>myLogFile1.log</file>
    <encoder>
        <pattern>%d [%thread] %-5level %logger - %msg%n</pattern>
    </encoder>
</appender>
<appender name="fileAppender2" class="ch.qos.logback.core.FileAppender">
    <filter class="ch.qos.logback.classic.filter.LevelFilter">
          <level>TRACE</level>
          <onMatch>ACCEPT</onMatch>
          <onMismatch>DENY</onMismatch>
    </filter>
    <file>myLogFile2.log</file>
    <encoder>
        <pattern>%d [%thread] %-5level %logger - %msg%n</pattern>
    </encoder>
</appender>
<appender name="console" class="ch.qos.logback.core.ConsoleAppender">
    <filter class="ch.qos.logback.classic.filter.LevelFilter">
          <level>DEBUG</level>
          <onMatch>ACCEPT</onMatch>
          <onMismatch>DENY</onMismatch>
    </filter>
    <encoder>
        <pattern>%d [%thread] %-5level %logger - %msg%n</pattern>
    </encoder>
</appender>

<logger name="my" level="INFO" additivity="false" >
    <appender-ref ref="fileAppender1" />
</logger>

<logger name="my.test" level="DEBUG" additivity="false" >
    <appender-ref ref="console" />
</logger>

<root level="TRACE">
    <appender-ref ref="fileAppender2" />
</root>

更新

如果您需要错误和警告，请使用带有警告的 ThresholdFilter(如下所示)，如果您需要信息、错误和警告，请使用阈值过滤器作为信息(我认为这是默认行为)

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