In log4j it's possible to define log levels by package as follows:
<logger name="org.springframework.web.servlet.mvc.method.annotation" level="info">
<AppenderRef ref="CONSOLE" />
</logger>
Questin: how can I define the logging for a specific class only? (eg org.springframework.web.servlet.mvc.method.annotation.EndpointHandlerMapping)? If I just put this into the <logger name property, nothing is logged anymore.

To define a custom log level in code, use the Level. forName() method. This method creates a new level for the specified name. After a log level is defined you can log messages at this level by calling the Logger.
Configuration: the root element of a log4j2 configuration file; the status attribute represents the level at which internal log4j events should be logged. Appenders: this element contains a list of appenders; in our example, an appender corresponding to the System console is defined.
It should work with fully qualified name as well. Logger.name doesnt have to be package/class only but it could be any name which you want to. When you call LoggerFactory.getLogger("MyLogger"), then you have to use
<Logger name="MyLogger" level="info">
<AppenderRef ref="CONSOLE"/>
</Logger>
Check what is logged when you use logger for package and use logger name from log. What logger name is logged for this class?
