Spring: Profiles and Environments

Original chapter: Spring profile. The text and examples below are preserved from the historical source; read the corrections above before using them.

Section 17.1: Spring Profiles allows to configure parts available for certain environment

Any @Component or @Configuration could be marked with @Profile annotation

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

    // ...
}

The same in XML config

<beans profile="dev">
   <bean id="dataSource" class="<some data source class>" />
</beans>

Active profiles could be configured in the application.properties file

spring.profiles.active=dev,production

or specified from command line

--spring.profiles.active=dev,hsqldb

or in SpringBoot

SpringApplication.setAdditionalProfiles("dev");

It is possible to enable profiles in Tests using the annotation @ActiveProfiles("dev")
