How many times have you had problems trying to make your bamboo plans prepared to run in different environments, i.e.: prod, testing, dev?

In the following example, I have a small web application that uses spring where I inject the url of the external service I want to use into a java class. I have a different url for different environments. Now I want to pass the environment I want to pass al the way from bamboo2 to java and spring. So from bamboo I will be able to define a plan for every environment so that I will be able to test every environment, deploy to every environment and so on.
I am assuming you have a good knowledge about spring, bamboo, maven and unit testing in general and the only thing you do not know is how to make it more generic.

Properties file:

configuration-local.properties:

app.url=http://localhost:8080/app

configuration-testing.properties:

app.url=http://testing:8080/app

configuration-production.properties:

app.url=http://production:8080/app

So we have a file for each configuration.

Spring config file:

applicationContext.xml:

<beans 
xmlns:context="http://www.springframework.org/schema/context" 
xmlns:mvc="http://www.springframework.org/schema/mvc" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns="http://www.springframework.org/schema/beans" 
xsi:schemalocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
              http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
              http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

 <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" id="propertyConfigurer">
  <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE">
  <property name="location" value="classpath:configuration-${env}.properties">
 </property></property></bean> 

 <bean class="com.miguel.app.App" id="app">  
  <property name="url" value="${app.url}">
 </property></bean>
</beans>

Maven

Configure surefire plugin:

   <plugin>
    <artifactid>maven-surefire-plugin</artifactid>
    <configuration>
     <environmentvariables>
      <env>${env}</env>
     </environmentvariables>
     <systemproperties>
        <property>
            <name>env</name>
            <value>${env}</value>
        </property>
     </systemproperties>
    </configuration>
   </plugin>

Bamboo:

In the plan go to configure job
set the goal:

test -Denv=dev
