spring中获得属性文件键值对，在程序中使用

!-- 	<context:property-placeholder -->
<!-- 		location="/WEB-INF/jdbc-config/jdbc.properties" /> -->
		<bean id="propertyConfigurer"  class="com.chinaGPS.nss.util.MyPropertyPlaceholderConfigurer">
		        <property name="locations">
		            <list>
		                <value>/WEB-INF/jdbc-config/httpRemote.properties</value>
		            </list>
		        </property>
		 </bean>

protected void processProperties(
ConfigurableListableBeanFactory beanFactoryToProcess,
Properties props) throws BeansException {
super.processProperties(beanFactoryToProcess,props);
for (Enumeration propertyNames = props.propertyNames(); propertyNames.hasMoreElements();) {
String propertyName = (String) propertyNames.nextElement();
String propertyValue = props.getProperty(propertyName);
String convertedValue = convertProperty(propertyName, propertyValue);
PropertiesPool.load(propertyName, convertedValue);
}
}
