public class EnvironmentPropertyConfigurer
extends org.springframework.beans.factory.config.PropertyPlaceholderConfigurer
implements org.springframework.context.ApplicationContextAware, org.springframework.beans.factory.config.SmartInstantiationAwareBeanPostProcessor

A propertyconfigurer that can be used to dynamically select a list of property files based on the current environment.

You can configure the fileLocation parameter with a list of file location, using variables for:

• the server name: ${env}
• the web application root folder name (only for web contexts): ${appl}
• any web context init parameter (only for web contexts): ${contextParam/paramname}

A sample value for the fileLocation parameter would be: WEB-INF/config/${env}/my.properties, WEB-INF/config/${appl}/my.properties, WEB-INF/config/${contextParam/instance}/my.properties, classpath:my-${env}.properties,classpath:default.properties.

After replacing all the known variables the resulting list is parsed and any existing file is merged in a single property list, used to configure the remaining spring context
