title: Spring REST Service Certificate auth
body: <p>I have written Spring controller. This get's requests from clients. It's just REST style. </p>
  
  <p>This is very good. But I need certificate authentication.  Only the clients must have access to the rest service (spring controller), which have client certificates with key (In the other words client should have keystore with key).</p>
  
  <p>How can I configure this security to spring? Could you give me an example or link where this is written?</p>
  
  <p>Thanks </p>
