Correct.
If you really need separate host configs, use split CATALINA_HOST,
CATALINA_BASE - see RUNNING.txt in your distribution.
Then you can refer to a resource inside Spring:
<util:properties id="appProps"
location="file:${catalina.base}/conf/app.properties"/>
<context:property-placeholder properties-ref="appProps"/>
