Implement recommendation from https://docs.spring.io/spring-boot/reference/features/external-config.html to use kebab case for @Values: If you do want to use @Value, we recommend that you refer to property names using their canonical form (kebab-case using only lowercase letters). This will allow Spring Boot to use the same logic as it does when relaxed binding @ConfigurationProperties. Signed-off-by: Avgustin Marinov <Avgustin.Marinov@bosch.com>
