title: spring-security ACL tutorial
body: <p>I need to add Roles and Permissions and Access-Lists to our project. I found <a href="http://docs.spring.io/spring-security/site/docs/3.2.3.RELEASE/reference/htmlsingle/#domain-acls" rel="nofollow">this</a> but I found it a bit too basic and specific. </p>
  
  <p>Is there a better tutorial/article/example that I should read or follow before implementing? </p>
