How can I use maven profile Id value in spring bean files? - spring

Question

mvn -P dev
If I build my project using profile dev, then I want to use dev.properties in my spring bean like below. Is it possible ? If so , how could I get profile name ?
<bean id="xyz" class="abc.xyz">
<property name="propertyFile" value="${maven_profile_id}.properties" />
</bean>
Thanks in advance.

Answer 1

You can use Maven profiles to add a 'profile' property to the build:
<profiles>
<profile>
<id>dev</id>
<properties>
<profile>dev</profile>
</properties>
</profile>
</profiles>
Then pass the value into your application using a system property, here's an example with surefire:
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<systemPropertyVariables>
<profile>${profile}</profile>
</systemPropertyVariables>
</configuration>
</plugin>
Finally this can be referenced in you application:
<bean id="xyz" class="abc.xyz">
<property name="propertyFile" value="${profile}.properties" />
</bean>
Alternatively, if you are using Spring 3.1 or later you might find the XML profile feature meets your needs (although it may be overkill).

Answer 2

Create a properties file that will be populated using Maven's resource filtering that specifies the profile you are using at build time.
build.properties
activatedProfile=${profileId}
pom.xml (You don't need to filter the complete directory, customise as required)
<build>
<resources>
<resource>
<directory>src/main/resources</directory>
<filtering>true</filtering>
</resource>
<resources>
</build>
Add a profileId (or whatever you want to call it) property under each different profile:
<profile>
<id>dev</id>
<properties>
<profileId>dev</profileId>
</properties>
</profile>
<profile>
<id>qa</id>
<properties>
<profileId>qa</profileId>
</properties>
</profile>
You can then use ${activatedProfile}.properties as value for a bean
<bean id="xyz" class="abc.xyz">
<property name="propertyFile" value="${activatedProfile}.properties" />
</bean>
