How to set spring active profiles with maven profiles

I have an application with maven as a build tool.

I am using maven profiles to set up different properties from different profiles.

What i would like to do is that all active profiles in maven will be ported to spring active profiles as well so i can reference them in bean signature (@profile). but i am not sure how to do it.

for example: consider the following maven setup

<profiles>
    <profile>
        <id>profile1</id>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
        <properties>
        </properties>
    </profile>
    <profile>
        <id>profile2</id>
        <properties>
        </properties>
    </profile>
    <profile>
        <id>development</id>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
        <properties>
        </properties>
    </profile>
    <profile>
        <id>production</id>
        <properties>    
        </properties>
    </profile>
</profiles>

assuming i run maven with out specifying any other profiles i would like for spring to have profile1 and development as active profiles.

There is a more elegant way to switch between 2 maven+spring profiles simultaneously.

First, add profiles to POM (pay attention - maven+spring profile is activated by single system variable):

<profiles>
    <profile>
        <id>postgres</id>
        <activation>
            <activeByDefault>true</activeByDefault>
            <property>
                <name>spring.profiles.active</name>
                <value>postgres</value>
            </property>
        </activation>
        <dependencies>
            <dependency>
                <groupId>postgresql</groupId>
                <artifactId>postgresql</artifactId>
                <version>9.1-901.jdbc4</version>
            </dependency>
        </dependencies>
    </profile>
    <profile>
        <id>h2</id>
        <activation>
            <property>
                <name>spring.profiles.active</name>
                <value>h2</value>
            </property>
        </activation>           
        <dependencies>
            <dependency>
                <groupId>com.h2database</groupId>
                <artifactId>h2</artifactId>
                <version>1.4.191</version>
            </dependency>
        </dependencies>
    </profile>
</profiles>

Second, set default profile for spring (for maven it is already set in POM). For web application, I inserted following lines to web.xml:

<context-param>
   <param-name>spring.profiles.default</param-name>
   <param-value>postgres</param-value>
</context-param>

Third, add profile-dependent beans to your config. In my case (XML config), it is:

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="dataSource" ref="mainDataSource" />
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
    </property>
    <property name="jpaProperties" ref="hibProps"/>
    <property name="packagesToScan">
        <list>
            <value>my.test.model</value>
        </list>
    </property>
</bean>
...
<beans profile="postgres">
    <bean name="mainDataSource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="org.postgresql.Driver" />
        <property name="url" value="jdbc:postgresql://127.0.0.1:5432/webchat" />
        <property name="username" value="postgres" />
        <property name="password" value="postgres" />
    </bean>
</beans>

<beans profile="h2">
    <bean name="mainDataSource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="org.h2.Driver" />
        <property name="url" value="jdbc:h2:file:./newsdb;INIT=RUNSCRIPT FROM 'classpath:init.sql';TRACE_LEVEL_FILE=0" />
        <property name="username" value="sa" />
        <property name="password" value="" />
    </bean>
</beans>

Now it is possible to:

  • Run my web-app on Postgres DB with mvn jetty:run or mvn jetty:run -Dspring.profiles.active=postgres commands
  • Run my web-app on H2 DB with mvn clean jetty:run -Dspring.profiles.active=h2
