title: How to inject a key-value map with Spring 4?
body: <pre><code>VI=Visa
  MC=Mastercard
  ...
  </code></pre>
  
  <p>Can I automatically inject this into a <code>Map&lt;String, String&gt;</code> with <code>Spring</code>?</p>
  
  <p>Like:</p>
  
  <pre><code>@Resource("${myfile.properties}")
  private Map&lt;String, String&gt; creditcards;
  </code></pre>
  
  <p>Is that possible?</p>
