title: spring-boot-devtools: how to exclude java classes from restarting the application?
body: <p>In Intellij IDEA with activating <code>spring-boot-devtools</code> in the maven configuration, I can update easily static web components and the javascript or html code updates are easily reflected in the running application.</p>
  
  <p>The disadvantage is that also my java classes get reloaded. This is something I want to avoid as I have some heavy classes with a loading time of up to two minutes.</p>
  
  <p>How is it possible to configure <code>spring-boot-devtools</code> that e.g. static web components get reloaded, but the server is not completely restarted (so that my Java class member variables stay untouched)?</p>
