how to use Spring Boot profiles

Question

i have application.yml,application-dev.ymlandapplication-dev.yml

1. I\'m using the maven command mvn spring-boot:run

Answer 1

Since Spring Boot v2+

I have verified with Spring Boot v2.3.5.RELEASE

With Spring Boot Maven Plugin

You can provide commandline argument like this:

mvn spring-boot:run -Dspring-boot.run.arguments="--spring.profiles.active=dev"

You can provide JVM argument like this:

mvn spring-boot:run -Dspring-boot.run.jvmArguments="-Dspring.profiles.active=dev"

java -jar

java -Dspring.profiles.active=dev -jar app.jar (Note order)

or

java -jar app.jar --spring.profiles.active=dev (Note order)

Answer 2

The @Profile annotation allows you to indicate that a component is eligible for registration when one or more specified profiles are active. Using our example above, we can rewrite the dataSource configuration as follows:

@Configuration
@Profile("dev")
public class StandaloneDataConfig {

    @Bean
    public DataSource dataSource() {
        return new EmbeddedDatabaseBuilder()
            .setType(EmbeddedDatabaseType.HSQL)
            .addScript("classpath:com/bank/config/sql/schema.sql")
            .addScript("classpath:com/bank/config/sql/test-data.sql")
            .build();
    }
}

And other one:

@Configuration
@Profile("production")
public class JndiDataConfig {

    @Bean(destroyMethod="")
    public DataSource dataSource() throws Exception {
        Context ctx = new InitialContext();
        return (DataSource) ctx.lookup("java:comp/env/jdbc/datasource");
    }
}

Answer 3

If you are using the Spring Boot Maven Plugin, run:

mvn spring-boot:run -Dspring-boot.run.profiles=foo,bar

(https://docs.spring.io/spring-boot/docs/current/maven-plugin/examples/run-profiles.html)

Answer 4

If you are using maven, define your profiles as shown below within your pom.xml

<profiles>
<profile>
    <id>local</id>
    <activation>
        <activeByDefault>true</activeByDefault>
    </activation>
    <properties>
        <jdbc.url>dbUrl</jdbc.url>
        <jdbc.username>dbuser</jdbc.username>
        <jdbc.password>dbPassword</jdbc.password>
        <jdbc.driver>dbDriver</jdbc.driver>
    </properties>
</profile>
<profile>
    <id>dev</id>
    <properties>
        <jdbc.url>dbUrl</jdbc.url>
        <jdbc.username>dbuser</jdbc.username>
        <jdbc.password>dbPassword</jdbc.password>
        <jdbc.driver>dbDriver</jdbc.driver>
    </properties>
    <dependencies>
        <dependency>
            <groupId>org.postgresql</groupId>
            <artifactId>postgresql</artifactId>
        </dependency>
    </dependencies>
</profile>
<profile>
    <id>prod</id>
    <properties>
        <jdbc.url>dbUrl</jdbc.url>
        <jdbc.username>dbuser</jdbc.username>
        <jdbc.password>dbPassword</jdbc.password>
        <jdbc.driver>dbDriver</jdbc.driver>
    </properties>
</profile>

By default, i.e if No profile is selected, the local profile will always be use.

To select a specific profile in Spring Boot 2.x.x, use the below command.

mvn spring-boot:run -Dspring-boot.run.profiles=dev

If you want want to build/compile using properties of a specific profile, use the below command.

mvn clean install -Pdev -DprofileIdEnabled=true

Answer 5

You can specify properties according profiles in one application.properties(yml) like here. Then mvn clean spring-boot:run -Dspring.profiles.active=dev should run it correct. It works for me

Answer 6

Working with Intellij, because I don't know how to set keyboard shortcut to mvn spring-boot:run -Dspring.profiles.active=dev, I have to do this:

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <configuration>
        <jvmArguments>
            -Dspring.profiles.active=dev
        </jvmArguments>
    </configuration>
</plugin>
