Questoion: How use log4j2 in static method?

Answer 1

Yo can use with LogManager , for example:

private static final Logger logger = LogManager.getLogger(ErrorHandler.class);

Here you have an example: https://logging.apache.org/log4j/2.x/manual/configuration.html

Answer 2

The Logger class in Log4j2 does not have a static getLogger(Class<?> c) method.

You are probably looking for the LogManager .
