title: Add trace.id and transaction.id Springboot
body: <p>I have a Springboot micro-service. For logging I'm using Elastic common scheme, implemented using <a href="https://github.com/elastic/ecs-logging-java/tree/master/log4j2-ecs-layout" rel="nofollow noreferrer">ecs-logging-java</a>.</p>
  
  <p>I want to set the trace.ID and a transaction.ID but I'm not sure how?</p>
  
  <p>Bonus question, I'm I right in thinking trace.ID should be the ID to following the request through multiple system. transaction.ID is just for within the service?</p>
