title: Hide datasource password in spring xml file
body: <p>there is a way to hide/encrypt password in xml spring config file?
  I read that is possible with a "custom" subclass of DataSource, but the solutions keep key in same config file as plain text...so is a bit useless.</p>
  
  <p>There is a way to use KeyStore for this?
  For example read the value from a keystore.</p>
  
  <p>Thanks all.</p>
