Как мне узнать полный путь к загруженной конфигурации log4j2?

Мой сервер приложений загружает файл log4j2.properties, и я не могу найти, где он находится.Я хотел бы знать полный путь этого файла конфигурации.

Я могу легко заставить log4j2 отображать найденные файлы конфигурации, если я запускаю jvm с опцией -Dlog4j.debug, как ответил в этот вопрос , но он не отображает полный путь.

С параметром отладки я получаю следующие выходные данные:

Поскольку последнее отображаемое имя файла - log4j2-test.xml, это загруженный файл.Проблема в том, что если я назову свой файл log4j2.xml, перед ним будет загружена другая конфигурация с именем log4j2.properties.И я не могу найти, где этот файл!Должен быть способ узнать, откуда он загружен.

В вашей программе вы можете сделать следующее: 

URL url = org.apache.logging.log4j.LogManager.class.getResource("/log4j2.properties");
System.out.println(url);

Это должно отобразить расположение файла "log4j2.properties" в корне пути к классу, используя загрузчик классов LogManagerучебный класс.
