title: How to add a custom Restful web service in JHipster?
body: <p>I'm new to Jhipster and looking through the documentation I see creating a service here: <a href="https://jhipster.github.io/creating-a-service/" rel="nofollow noreferrer">https://jhipster.github.io/creating-a-service/</a>
  but nothing on adding a simple, secured, custom web service.</p>
  
  <p>I've successfully added an entity and can access (i.e. curl) the data with the command given in the swagger description. I'd like to augment that default service and add a second custom service that tweaks the json format returned. Is there an easy way to do that?</p>
