property not found with multiple context:property-placeholder

Question

I am using spring 3.1 with spring profiles to load the beans. In my app context file, I load the properties like :

Answer 1

In my application I am using property-placeholder configurer in following way and it works very well. You can try that.

<bean id="propertyConfigurer"
          class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
          <property name="locations">
            <list>
                <value>classpath*:META-INF/spring/*_${spring.profiles.active}.properties</value>
            </list>
          </property>
    </bean>

I think this should resolve your problem. :)

Answer 2

Since you have suggested hardcoding the path to the configuration file works, try using the profiles attribute on the tag to selectively include the configuration.

<beans profile="profileName">
    <context:property-placeholder  order="1"  location="classpath*:META-INF/spring/hardcoded.properties" ignore-unresolvable="true"/>
</beans>

<beans profile="profileName2">    
    <context:property-placeholder order="1"  location="classpath*:META-INF/spring/hardcoded.properties" ignore-unresolvable="true"/>
</beans>

See this article explaining profiles: http://java.dzone.com/articles/using-spring-profiles-xml

Answer 3

This bug about multiple property placeholders might relate to your problem: https://jira.spring.io/browse/SPR-9989

When using multiple PropertyPlaceholderConfigurer in conjunction with @Value annotation and default value for placeholders syntax (ie ${key:defaultValue}), only the first PropertyPlaceholderConfigurer is used. If this configurer does not contain the desired value, it falls back to @Value default even if the second PropertyPlaceholderConfigurer contains the value.

Affects Version/s: 3.1.3

Answer 4

Each <context:property-placeholder> creates a new instance of PropertyPlaceholderConfigurer - it gets messy easily. You should have one such thing per application and on application level, not on libraries' one - that makes maintenance much easier.
