title: How to reference a spring bean explicitly in a SpEL expression
body: <p>Hi I have a spring bean named "connection" - how can I reference that explicitly in a SpEL expression from webflow - by explicitly I mean I don't want SpEL to try and find any other variables named "connection" which may exist in webflow scope - this is what I'm currently doing:</p>
  
  <pre><code>&lt;action-state id="initialise-connection"&gt;
      &lt;evaluate result="flowScope.initialisedConnection" expression="connection"/&gt;
  </code></pre>
  
  <p>I've read about prefixing with "@" to only target beans - what is the right practice and how do I do it?</p>
