- Command-line arguments: You can pass command-line arguments to your Spring Boot application when it starts up, which can be used to override the default configuration settings.
- Environment variables: You can use environment variables to configure your Spring Boot application, which can be especially useful when deploying to cloud platforms.
- Configuration classes: You can create custom configuration classes in your application that use Spring’s
@Configurationannotation to define beans and other configuration settings.
- Profiles: You can define different profiles for your Spring Boot application, which can be used to configure different environments such as development, staging, and production.
- External configuration sources: Spring Boot also supports external configuration sources such as properties files, YAML files, JSON files, and even databases, which can be used to store configuration settings outside of your application code.
In summary, Spring Boot provides a wide range of configuration options that can be used to customize the behavior of your application, and it supports various sources of configuration, including files, command-line arguments, environment variables, and external configuration sources.
