title: How To Log When Invalid Bearer Token Is Sent To Backend
body: <p>I have a Jhipster built backend and am looking to log when an invalid authentication Bearer token is sent with a request.</p>
  <p>Currently using Postman I can send a valid token to get information I need and that is logged like so:</p>

  <p>When I send an invalid token I get back a response with a status of 401 and headers saying 'invalid_token' which is perfectly fine, but nothing is logged in the application.</p>
  <p>It seems like the code that handles this comes from Spring Security dependency. Is there any way to have it log out more information?</p>
