Configuration properties binding

Configuration properties binding is a mechanism in Spring Boot that allows developers to map external configuration (from files like application.properties or application.yaml) to the fields of a Java class.^[600-developer-spring-springboot2.md]

Implementation Methods

Spring Boot provides two primary approaches to enable configuration properties binding^[600-developer-spring-springboot2.md]:

  1. @Component + @ConfigurationProperties: The class is annotated with @Component (or any other stereotype annotation) to be registered as a bean, and @ConfigurationProperties is applied to specify the prefix for binding properties.

  2. @EnableConfigurationProperties + @ConfigurationProperties: This approach is typically used in configuration classes. @EnableConfigurationProperties is used to register the configuration properties class with the Spring container, while the class itself is annotated with @ConfigurationProperties.
