Loading properties based on maven profiles?

Question

I am using spring 3.2. I am trying to load properties file based on maven profile as below.

<build>
    <resources>
      <resource>
        <directory>src/main/resources</directory>
        <filtering>true</filtering>
      </resource>
    </resources>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.1</version>
        <configuration>
          <source>1.7</source>
          <target>1.7</target>
        </configuration>
      </plugin>

      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>2.17</version>
        <configuration>
            <includes>
                <include>**/*Test.java</include>
            </includes>
        </configuration>
    </plugin>

    </plugins>
  </build>

  <profiles>
        <profile>
            <id>dev</id>
            <activation>
                <activeByDefault>true</activeByDefault>
            </activation>
            <properties>
                <env>dev</env>
            </properties>
        </profile>
        <profile>
            <id>prod</id>
            <properties>
                <env>prod</env>
            </properties>
        </profile>
    </profiles>

applicationContext.xml

<bean id="props" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations" value="classpath:props/connection-${env}.properties"/>
    </bean>

here {env} should be replaced by maven profile.but it is not replacing. am getting below exception.

org.springframework.beans.factory.BeanInitializationException: Could not load properties; nested exception is java.io.FileNotFoundException: class path resource [props/connection-{env}.properties] cannot be opened because it does not exist.

I am loading application context as:

ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("classpath:spring/applicationContext.xml");

when i do clean install {env} value has to be replaced by maven profile.

any help?

Any reason you're using Maven (build time) profiles instead of Spring (runtime) profiles in this case, or are the Maven profiles also used for other things? — Emerson Farrugia, Aug 19 '14 at 14:50

you are right. It is not enough. 1. **You need to add properties to profile** ( dev1 ). 2. **Add filting to resoureces** ( src/main/resources true ). After this you can use params via ${} – Natalia Aug 19 '14 at 14:41

Your applicationContext.xml file should be in src/main/resources and your maven build should include a profiles section containing at least (I'm typing without checking)

    <profile>
        <id>prod</id>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
        <properties>
            <env>prod</env>
        </properties>
    </profile>

If all these conditions are met, I suggest you run mvn -X -e which will log you all what happens during build.

Lookup specifically for calls to org.apache.maven.plugins:maven-resources-plugin. There should be at least one call to that plugin and its configuration should include

[DEBUG] Configuring mojo org.apache.maven.plugins:maven-resources-plugin:2.6:copy-resources from plugin realm ClassRealm[plugin>org.apache.maven.plugins:maven-resources-plugin:2.6, parent: sun.misc.Launcher$AppClassLoader@77abfbdc]
[DEBUG] Configuring mojo 'org.apache.maven.plugins:maven-resources-plugin:2.6:copy-resources' with basic configurator -->
[DEBUG]   ....
[DEBUG]   (s) filtering = true
[DEBUG]   ....

A few months ago, I was learning this very thing, of how to use maven profiles. The guide can be shown on Apache's site, but I will show what is needed below.

It looks like you set up your maven profile correctly. However, you seem to be missing your profile setting in .m2/settings.xml:

<profiles>
    <profile>
        <id>dev</id>
        <properties>
            <environment>dev</environment>
        </properties>
    </profile>
</profiles>

Optionally, you can set your maven profile when building with the following command:

mvn -Denv=dev

But if you don't want to specify this flag everytime you build, it is recommended to place your profile in your maven settings.xml file.

try to setup something like below in your maven for each of your profiles:

For example dev profile :

<plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-surefire-plugin</artifactId>
   <configuration>
      <systemPropertyVariables>
         <env>dev</env>
      </systemPropertyVariables>
   </configuration>
</plugin>

Test Profile:

<plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-surefire-plugin</artifactId>
       <configuration>
          <systemPropertyVariables>
             <env>test</env>
          </systemPropertyVariables>
       </configuration>
    </plugin>

you can use mvn -P clean install or set something like true in your profile which you want to run, is this what you are looking for? – user3487063 Aug 19 '14 at 14:58
