title: Use PropertyPlaceholderConfigurer with List
body: <p>I am using PropertyPlaceholderConfigurer to map String values from properties file and it works ok.</p>
  
  <p>My question is if I can set something the this in my property file:
  myList=A,B,C</p>
  
  <p>And then map it to a list</p>
  
  <pre><code>@Value("${myList}")
  private List&lt;String&gt; myList;
  </code></pre>
  
  <p>When I try that it puts all the values in one place of the list.
  Is there any way to tell it to break this to a list by ","?</p>
