title: Hibernate Envers custom field for user input
body: <p>I'm using Spring Boot and Hibernate Envers with a custom <code>RevisionEntity</code> and <code>RevisionListener</code> to store additional information like username, ip in the revision info. It works fine.</p>
  
  <p>As a new requirement I also need to store modification comment from the user. So if a user changes an entity he/she also needs to enter a reason for this change. This text should be saved among the other revision information.</p>
  
  <p>I have the text in my <code>Controller</code> and in the <code>Service</code> class as well, but how can I populate the <code>RevisionListener</code> with this information?</p>
