title: How can I decorate the REST response in Spring (Boot)?
body: <p>I've got a Spring Boot application that returns various objects that get encoded as JSON responses and I'd like to post-process them and add information to certain super classes. </p>
  
  <p>Is there a way to filter, intercept, etc. the object responses from my REST endpoints before they get encoded to JSON with Jackson. </p>
  
  <p>A filter won't work since it operates at the <code>HttpServlet{Request,Response}</code> level. </p>
