title: Refresh context without refreshing configuration from file
body: <p>Is it possible to refresh context without refreshing configuration ?<br/><br/>
  I found method <code>ConfigurableApplicationContext.refresh()</code> but it refresh configuration from file.
  I would like to do below steps in runtime:</p>
  
  <ol>
  <li>get context and bean</li>
  <li>change bean property value</li>
  <li>refresh context</li>
  </ol>
