title: Programmatic access to properties created by property-placeholder
body: <p>I'm reading properties file using <code>context:property-placeholder</code>. How can I access them <strong>programatically</strong> (<code>@Value</code> doesn't work - I don't know property titles at the moment of developing)?</p>
  
  <p>The main problem is I can't change <code>applicationContext.xml</code> file because it's setted up by "parent" framework</p>
  
  <p>ps. It's strange but <code>Environment.getProperty</code> returns <code>null</code></p>
