java - Logback能否根据用户动态生成不同的User日志文件？

Question

logback的配置文件中可以定义<property>变量，就好像下面代码的“${LOG_HOME}”：

<property name="LOG_HOME" value="c:/log" />
<appender name="FILE"  class="ch.qos.logback.core.rolling.RollingFileAppender">   
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <FileNamePattern>${LOG_HOME}/myApp.log.%d{yyyy-MM-dd}.log</FileNamePattern>   
    </rollingPolicy>   
    <layout class="ch.qos.logback.classic.PatternLayout">  
        <pattern></pattern>   
   </layout>
</appender>

想知道，怎么通过Java代码动态的修改LOG_HOME的值？

Answer 1

Yes, it is possible. I remember using MDC to save the user name, and then output it to different log files based on the user name.

Answer 2

I don’t know what project you are using?

Answer 3

Yes, please check the official website. There is a chapter introducing this feature.
