override property value ${abc.xyz} in bean property in spring configuration file

Question

I have beans xml file, which loads multiple property files for creating its beans. All these property files are under a root folder like root/abc/abc.properties , root/xyz/some.properties etc..

<bean id="x".....
....
<util:properties id="properties" location="${config.base.dir}/abc/abc.properties" />
......
</bean>


<bean id="y".....
....
<util:properties id="properties" location="${config.base.dir}/xyz/some.properties" />
......
</bean>

I want to override put the value of config.base.dir somewhere in top so that I can keep changing the root location, should this be possible by defining some property on top?

Answer 1

If using Maven, you can have a version of abc.properties in the test/resources/abc/ folder. this will be picked up on the classpath before the main/resources/abc/abc.properties file.

Does this help?

Why do you want to ' keep changing the root location' ?
