title: Add configuration directory to classpath using spring boot
body: <p>I would like to add a configuration directory to the classpath for  a spring boot application at start up, so it can load xml files from the configuration directory.</p>
  
  <p>ie /var/application/config contains
  test.xml, dev.xml</p>
  
  <p>The xml will contain mapping information that is required by the application; this is different from application.properties.</p>
  
  <p>I would like to load them at startup.</p>
  
  <p>I am using ClassPathResource to load the files.</p>
  
  <p>Please advise.</p>
