title: Require initial setup before running spring web app
body: <p>I'm creating a very simple forums application. </p>
  
  <p>My current problem is i want the user to be prompted with a setup page (what they'll use to set initial settings such as MySQL credentials) if the website has yet to be setup. When they attempt to go to <code>website.com/login</code>, it should redirect them to <code>website.com/setup</code> until the setup is fully finished. </p>
  
  <p>Should i just use an interceptor for this, or is there an alternative? Also, if i use an interceptor, is it possible to "unregister" it when the website has been fully setup? </p>
