Setting the default active profile in Spring-boot

Question

I want my default active profile to be production if -Dspring.profiles.active is not set.

I tried the following in my application.pro

Answer 1

One can have separate application properties files according to the environment, if Spring Boot application is being created. For example - properties file for dev environment, application-dev.properties:

spring.hivedatasource.url=
spring.hivedatasource.username=dev
spring.hivedatasource.password=dev
spring.hivedatasource.driver-class-name=org.apache.hive.jdbc.HiveDriver

application-test.properties:

spring.hivedatasource.url=
spring.hivedatasource.username=test
spring.hivedatasource.password=test
spring.hivedatasource.driver-class-name=org.apache.hive.jdbc.HiveDriver

And a primary application.properties file to select the profile:

application.properties:

spring.profiles.active=dev
server.tomcat.max-threads = 10
spring.application.name=sampleApp

Define the DB Configuration as below:

@Configuration
@ConfigurationProperties(prefix="spring.hivedatasource")
public class DBConfig {

    @Profile("dev")
    @Qualifier("hivedatasource")
    @Primary
    @Bean
    public DataSource devHiveDataSource() {
        System.out.println("DataSource bean created for Dev");
        return new BasicDataSource();
    }

    @Profile("test")
    @Qualifier("hivedatasource")
    @Primary
    @Bean
    public DataSource testHiveDataSource() {
        System.out.println("DataSource bean created for Test");
        return new BasicDataSource();
    }

This will automatically create the BasicDataSource bean according to the active profile set in application.properties file. Run the Spring-boot application and test.

Note that this will create an empty bean initially until getConnection() is called. Once the connection is available you can get the url, driver-class, etc. using that DataSource bean.
