title: SpEL reference instance variable of class
body: <p>I am using a custom method for my spring security pre authorize annotation and I need to pass a long list of perms in. I want to store that list externally because its used in a few places butI can't seem to figure out how to reference said list. It seems to always come through as null. </p>
  
  <pre><code>@RestController
  @RequestMapping("/example")
  public class MyController  {
  
  ...constructor/other stuff
  public List&lt;String&gt; perms_I_want_to_reference = Arrays.asList("super","long","list")
  
  @PreAuthorizze("@securityService.MyCustomMethod(principal, *this where I want to reference perms*)
  @RequestMapping(method = RequestMethod.GET)
  public ResponseEntity&lt;?&gt;doSomethingTopSecret(){
  }
  
  }
  </code></pre>
  
  <p>I have tried # and making list static and using <code>T</code> but so far nothing is working.  </p>
