title: Grails Spring Security 3 service springSecurityService is null
body: <p>springSecurityService service in User is always null</p>
  
  <p>I can't seem to reference the package itself in the following manner</p>
  
  <pre><code>import grails.plugin.springsecurity.*;
  </code></pre>
  
  <p>though spring security login page does appear, and gradle doesn't complain on anything missing.</p>
  
  <p>seems like no DI is taking place.</p>
  
  <p>User</p>
  
  <pre><code>package com.sciencecanvas.mykingdom

      private static final long serialVersionUID = 1

      String password
