Profiles

Profiles provide a way to customize the configuration of an application based on different environments or scenarios

Here's an explanation of Java Spring profiles:

  1. Definition in Configuration: Profiles in Spring allow you to define sets of beans and configurations that will be active only when a specific profile is activated. You can have different configurations for different profiles, and Spring will activate the appropriate set of configurations based on the active profile.

  2. Profile Activation: Profiles can be activated in various ways, and Spring provides flexibility in choosing the activation mechanism. Some common methods include:

    • Using the -Dspring.profiles.active system property when starting the application.
    • Setting the SPRING_PROFILES_ACTIVE environment variable.
    • Programmatically setting active profiles in the code.

  3. Profile-Specific Configuration: Within your Spring configuration files (XML, Java Config, or annotations), you can use the @Profile annotation to specify that a particular configuration should be active only when a certain profile is active. For example:

@Configuration
@Profile("development")
public class DevelopmentConfig {
    // Configuration specific to the "development" profile
}
  1. Properties Files: You can also use properties files to define profile-specific configurations. For instance, you can have application.properties for default configurations and application-{profile}.properties for profile-specific configurations. Spring will load the appropriate properties file based on the active profile.
# application.properties
database.url=default-url

# application-development.properties
database.url=development-url
