title: Spring boot multiple log files
body: <p>In my Spring boot project with "@Slf4j" annotated classes, for certain classes I want to log to a different file. But couldn't figure out how to do that. I have one logback-spring.xml file, which is referenced from my properties file like this:</p>
  
  <pre><code>logging.config= path/to/logback-spring.xml
  logging.file=myCurrentLogFile.log
  </code></pre>
  
  <p>Do I have to create another logback-spring.xml file now? or I can configure it in current file, and if then how can I choose which logger to use when.</p>
