To load multiple property files using Spring’s PropertyPlaceholderConfigurer, add <property name=”ignoreUnresolvablePlaceholders” value=”true” /> to the one that is loaded first like so:
<bean id=”propertyConfigurer”
class=”org.springframework.beans.factory.config.PropertyPlaceholderConfigurer”>
<property name=”location” value=”classpath:jdbc.properties” />
<property name=”ignoreUnresolvablePlaceholders” value=”true” />
</bean><bean id=”mailPropertyConfigurer”
class=”org.springframework.beans.factory.config.PropertyPlaceholderConfigurer”>
<property name=”location” value=”classpath:mail.properties” />
</bean>
This will make sure both files are loaded.

Just wanted to point out, it is also possible to use the ‘locations’ property of a single PropertyPlaceholderConfigurer:
sample1.properties
sample2.properties

with escaped xml this time…
<bean class=”org.springframework.beans.factory.config.PropertyPlaceholderConfigurer”>
<property name=”locations”>
<list>
<value>sample1.properties</value>
<value>sample2.properties</value>
</list>
</property>
</bean>

Thanks!

Thanks heaps, multiple files using locations is just what I wanted. btw, In case any punters need to know how to reference properties in spring:

that should have read:
.. < constructor-arg index=”3″ value=”${notifications.fromName.hoojano}” ..

constructor-arg index=”3″ value=”${notifications.fromName.hoojano}”

very interesting, but I don’t agree with you

@Idetrorce: There were no opinions offered, how do you not agree with a usage example?

The ignoreUnresolvablePlaceholders is helpful when you have multiple Spring xml configurations file and each needs its own properties file. You can make it work with locations as well but the former is more cleaner IMO.
Thanks!

This is quite a up-to-date information. I’ll share it on Facebook.
