title: How to read context-param (web.xml) values in a resources.groovy grails 2.3
body: <p>I need to get context-param values from a web.xml to override values in a resources.groovy.
  The Grails documentation purpose just to use a placeholder with a property file but the solution is not appropriate because in the future I want to use deployment plan with weblogic to override the context-param for different environnement. It's impossible to use ServletContextPropertyPlaceholderConfigurer because is deprecated now. Have you a solution ?</p>
  
  <p>Thank you</p>
