title: Run Spring boot .jar file with spring.config.location with replace values of application.properties?
body: <p>When I run a Spring boot application from command line with <code>--spring.config.location=another.properties</code>, values in <code>another.properties</code> will be overridden the values in <code>application.properties</code> ?</p>
  
  <p>For example:</p>
  
  <p>If there is a value <strong><code>spring.datasource.url</code></strong> in <code>application.properties</code>, but not in <code>application.properties</code>. So the value is taken from <code>another.properties</code> or undefined ?</p>
