Gumtree : Spring configuration management in Equinox

Created by Tony Lam, last modified on May 21, 2008

Spring supports configuration management via properties substitutiion in its XML bean context.  The following is the XML example:

  <bean id="propertyPlaceholderConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/>
    <property name="properties">
      <props>
        <prop key="restlet.serverPort">9876</prop>
      </props>
    </property>
  </bean>
 
  <bean id="jettyServer" class="com.noelios.restlet.equinox.JettyStarter" init-method="init" destroy-method="cleanup">
    <property name="port" value="${restlet.serverPort}" />
  </bean>

System properties should look something like this: 

# Production port
restlet.serverPort = 9999

Above uses the system properties to override the bean settings.  In Equinox, all system property are kept in the config.ini.  To enable the Spring PropertyPlaceholderConfigurer, you need to import package org.springframework.beans.factory.config.  This placeholder allows default settings (in case it cannot resolve from the system properties).  To enable this, import package org.springframework.core.io.support.
