Clean Code Rules for the Spring Boot

Use @ConfigurationProperties instead of @Value

^{Rule-ID: springboot.context-no-value-annotation}

Spring provides the annotation org.springframework.beans.factory.annotation.Value to inject properties from external property sources into the application context. While this is handsome in plain Spring applications, Spring Boot offers something better: org.springframework.boot.context.properties.ConfigurationProperties. This has the following advantage:

• No magic strings anymore inside @Value
• Typed and reusable properties
• Code completion in application.yaml and application.properties files when using the org.springframework.boot:spring-boot-configuration-processor
