[logback-user] Dynamically change a variable value for file location

[Ceki Gulcu]

Hi Douglas,


The <file> property is optional RollingFileAppender. Without it, 
RollingFileAppender will behave in the way you want.

Try the following:

<appender name="FILE" 
class="ch.qos.logback.core.rolling.RollingFileAppender">

  <rollingPolicy
   class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
     <fileNamePattern./log/%d{MMdd}/gp2b.log</fileNamePattern>
     <maxHistory>30</maxHistory>
  </rollingPolicy>
  <encoder>
     <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36}:%L - 
%msg%rEx{10}%n</pattern>
  </encoder>
</appender>

Let us know how it goes.
