Logback - additivity

代码

<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"><layout class="ch.qos.logback.classic.PatternLayout"><pattern>%-15(%d{HH:mm:ss.SSS}) [%t] %-5level %logger{80} [%line] -%msg%n</pattern></layout>
</appender><appender name="SIFT" class="ch.qos.logback.classic.sift.SiftingAppender"><discriminator><key>module</key><defaultValue>module</defaultValue></discriminator><sift><appender name="FILE-${module}" class="ch.qos.logback.core.rolling.RollingFileAppender"><Encoding>UTF-8</Encoding><rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"><FileNamePattern>${log.root}/${module}/${module}.%d{yyyy-MM-dd}.log</FileNamePattern></rollingPolicy><layout class="ch.qos.logback.classic.PatternLayout"><pattern>%-15(%d{HH:mm:ss.SSS}) [%t] %-5level %logger{80} [%line] -%msg%n</pattern></layout></appender></sift>
</appender><root level="info"><appender-ref ref="STDOUT"/><appender-ref ref="SIFT"/>
</root><logger name="com.shangyu" level="debug" additivity="true"><appender-ref ref="STDOUT" /><!--<appender-ref ref="SIFT" />-->
</logger>

STDOUT 是打印在控制台，控制台的日志如下

19:33:04.696    [http-nio-8080-exec-2] DEBUG com.shangyu.demo.mapper.UserMapper.selectById [143] -==>  Preparing: SELECT id,name,age,address,father_name FROM alin_user WHERE id=?

SIFT 是打印日志到文件，粘一些文件中的日志如下

19:33:04.696    [http-nio-8080-exec-2] DEBUG com.shangyu.demo.mapper.UserMapper.selectById [143] -==>  Preparing: SELECT id,name,age,address,father_name FROM alin_user WHERE id=?

19:33:04.768    [http-nio-8080-exec-2] INFO  com.shangyu.demo.controller.UserController [35] -info

19:33:04.769    [http-nio-8080-exec-2] DEBUG com.shangyu.demo.controller.UserController [37] -debug

总结

当additivity设为true时，这个logger标签会继承root，也就不仅仅打印自己的日志，还会打印root的日志，打印两遍。所以一般情况下都会设置成false
