In Spring-boot, which class reads the logging.* in application.yml ?

for (String name : applicationContext.getBeanNamesForAnnotation(ConfigurationProperties.class)) {

            System.out.println(name);

        }

I tried the above code, but the one I'm looking for is not listed. spring-docs doesn't mention it. No luck searching the source.

First (specific) question: how to find the class who reads and auto-configures logging.* properties?

Second (much wider) question: how to find the respective @ConfigurationProperties for a specific module in spring-boot?

Spring boot's logging classes are in the org.springframework.boot.logging package. It doesn't work using the @ConfigurationProperties method that you've been searching for. Logging properties are transferred to environment variables in the LoggingSystemProperties class and then those environment variables are referenced in the provider's configuration file, e.g. the logback XML config files.
