Subject config.properties substitution into applicationcontext.xml
Date Tue, 11 Nov 2008 22:14:48 GMT

I'd like to extract out some Camel URI settings from Spring
applicationContext.xml into a config.properties to make it easier to manage
and more obvious to the IT deployment person what has to be customized in
the production environment.  However, if I try using property values, I get
an exception in that it tries to interpret the ${property} as a string.

config.properties
fromEmailServerUri=imap://user@server.company.corp:143?password=abcde&amp;consumer.delay=3600000&amp;processOnlyUnseenMessages=true&amp;deleteProcessedMessages=false


applicationContext.xml
	<context:property-placeholder location="classpath:config.properties" />
	
	<camel:camelContext id="camel">
		<camel:route>
			<!--
				Poll every hour
				&amp;deleteProcessedMessages=true&amp;debugMode=true&amp;
			-->
			<camel:from uri="${fromEmailServerUri}" />
			<camel:to uri="bean:mailReader" />
		</camel:route>
	</camel:camelContext>
