PropertyPlaceholderConfigurer: environment variable for file location

[akarypid]

Hello,

I'm looking at the PropertyPlaceholderConfigurer.

http://static.springsource.org/sprin...lderconfigurer

Is it possible do define the location of a properties file using an environment variable?

So, one would:

set MY_APP_CFG=/path/to/custom.properties

and then the application context would pick them up with something like:

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="locations">
        <value>envPath:MY_APP_CFG</value>
    </property>
</bean>

you can do it this way

        <bean 
		id="placeholderConfigConfig" 
		class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"
		p:ignoreUnresolvablePlaceholders="true">
		p:systemPropertiesModeName="SYSTEM_PROPERTIES_MODE_OVERRIDE"/>
	</bean>

	<bean 
		id="propertyConfigurer" 
		class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"
		p:ignoreUnresolvablePlaceholders="true"
		p:location="${name_of_your_env_property}">    		
	</bean>
