: The logging system was initialized very early in the application life cycle. Therefore, you cannot set the log properties in the properties file through the @propertysource comment. Spring Boot's log properties are independent of the underlying components (such as Logback), so the properties of the component (such as Logback's Logback.configurationfile) are not managed by spring
