How to use it as as Bean in java class based configuration without using @ComponentScan?

How to use it as as Bean in java class based configuration without using @ComponentScan?

@naveenvignesh5 You should mention MyLoggerConfig in context initialization:
AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(MyLoggerConfig.class, SportConfig.class);

@evoyager
Should this be done even if @componentscan is enabled?

I have added the mylogger.properties file, also added the MyLoggerConfig class with a @configuration annotation. However, the logs do not appear until I explicitly mention the name of the logger as you have mentioned.

Am I missing something here?
