java - Subsets of Properties With Spring -

suppose have properties file contents looking this:

local.jndi.datasource = localdatasource dev.jndi.datasource = devdatasource test.jndi.datasource = testdatasource prod.jndi.datasource = proddatasource

i have scheme variables called "app.configdir" , "app.environment". app.environment variable can "local","dev","test", or "prod".

what this:

<context:property-placeholder location="file:#{systemproperties['app.configdir'] }/>

however, have properties narrowed downwards subset defined in environment variable.

is there relatively easy way in xml configuration? can think of couple of ways if able utilize programatic configuration.

edit: using spring 3.1.

you should able utilize spring profiles of spring 3.1. in config can have multiple , place

<beans profile="local"> <context:property-placeholder order="1" location="classpath*:meta-inf/spring/some.properties"/> </beans> <beans profile="dev"> <context:property-placeholder order="1" location="classpath*:meta-inf/spring/someother.properties"/> </beans>

see next link total illustration on using spring profiles: http://java.dzone.com/articles/using-spring-profiles-xml
