title: Spring local and system properties
body: <p>It is possible use local properties(declared in applicationContext.xml) in spring only if system properties(from operation system) not set. Now local properties overrided all system properties. I want that priority of system properties will be more that local.</p>
  
  <p>I import local properties from file and system properties set in operation system:</p>
  
  <p><code>&lt;context:property-placeholder location="classpath:localhost.properties" /&gt;</code></p>
  
  <p>I can't implement a custom PropertyPlaceholders.</p>
