Overriding System property in Spring PropertyPlaceHolderConfigurer for integration testing -

i'm using system property define location environment-specific properties file. however, override value different integration tests.

here's production spring setup. i'm using custom propertyplaceholderconfigurer resolve encrypted property file values, that's not important here:

<-- spring configuration in file service-spring-beans.xml --> <bean class="com.mycompany.mypropertyplaceholderconfigurer">     <property name="locations">         <list>             <value>classpath:properties/${my_environment}/${my_environment}.properties</value>         </list>     </property>     <property name="ignoreresourcenotfound" value="false"/>     <property name="ignoreunresolvableplaceholders" value="true"/> </bean> 

at runtime, define value of my_environment java system property. works expected. however, integration tests, define my_environment "inttest", integration-test specific property file properties/inttest/inttest.properties loaded.

i've tried use spring context loaded integration-test set string bean id my_environment:

<?xml version="1.0" encoding="utf-8"?> <beans xmlns="http://www.springframework.org/schema/beans"        xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"        xmlns:context="http://www.springframework.org/schema/context"        xsi:schemalocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">       <context:component-scan base-package="com.mycompany.myclasses"/>       <bean class="java.lang.string" id="my_environment">         <constructor-arg value="inttest"/>     </bean>     <!-- imports production spring context -->     <import resource="classpath:service-spring-beans.xml"/>  </beans> 

however, value of my_environment not resolved , , error when running integration tests.

caused by: org.springframework.beans.factory.beaninitializationexception: not load properties; nested exception java.io.filenotfoundexception: class path resource [properties/${my_environment}/${my_environment}.properties] cannot opened because not exist

how can override my_environment @ inttest time without passing system property jvm?

since using maven surefire plugin run integration tests, simplest solution turned out setting system property using surefire plugin configuration, this:

<configuration>   <systempropertyvariables>       <my_environment>inttest</my_environment>    </systempropertyvariables>    <!-- ... --> <configuration>
