Can not load property file in spring-context.xml. Property file Path is given as a placeholder in dev.properties - spring

Question

I am loading property file in spring-context.xml and i am giving
external property file location in
${spring.profiles.active}.properties which is in classpath and using the location as a placholder in spring-context.xml. My spring-context.xml is:
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="ignoreResourceNotFound" value="true" />
<property name="ignoreUnresolvablePlaceholders" value="true" />
<property name="searchSystemEnvironment" value="true" />
<property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />
<property name="locations" ref="propertyConfigurerFiles" />
</bean>
<bean id="propertyConfigurerFiles" class="java.util.ArrayList">
<constructor-arg>
<list>
<value>/WEB-INF/properties/common.properties</value>
<!--In Developemnet Enviroenment it will be dev.properties-->
<value>/WEB-INF/properties/${spring.profiles.active}.properties</value>
<!--External Property File Location as a Placeholder-->
<value>${app.config.batch.location}</value>
</list>
</constructor-arg>
</bean>
And my dev.properties is:
app.config.batch.location=E:/project/properties/config.properties
My problem is that is ${app.config.batch.location} placeholder is not
resolved in spring-context.xml and its trying to load file
${app.config.batch.location} in place of
E:/project/properties/config.properties.
I hope I explained the problem well. Please help!
Thanks in Advance!!!

Answer 1

You need to create bean of class PropertyPlaceHolderConfigurer.
Not just some ArrayList bean. Why do you think you need this ArrayList bean?

Answer 2

It seems you are using spring profiles, instead of messing with initialization time property value binding what you can do is ...
1) read the property file(profile's)
/WEB-INF/properties/${spring.profiles.active}.properties
2) create a java class that can read these property values. (don't forget to use spring profiles interfacing class)
3) as you are trying to read a property file whose location is embedded in property file(step-1), object created at step-2 will give value for key <value>${app.config.batch.location}</value>
now you can load this property file using available file reader class.
4) create Properties object and access the values in it.
Note:: if any of your bean initialization depends on key-value read at step-4, do initialization manually or create your ***custom class(servlet) that get loaded before any other class (even spring's DispactherServlet).
