title: Spring Boot App - Reference external code during runtime that isn't part of the bundled WAR?
body: <p>I have a Spring Boot+React application that is packaged as a bundled WAR.</p>
  
  <p>This works well for most cases, but we need to be able to drop-in functionality in some cases that is not part of the bundle (such as via a JAR).</p>
  
  <p>I knew OSGI exists for this case, but not sure of any usage with Spring Boot. Is there another way to do this as well?</p>
