Файл конфигурации: SRC/основные/ресурсы/log4j2.component.properties
log4j.configurationFactory=com.websitester.config.MPLoggingConfiguration$MPConfigurationFactory
В моем случае, я установил все свойства (доступ в MPLoggingConfiguration через System.getProperty) в других классах, например:
System.setProperty("log4jjdbcjndiName", "weblogic-monitor");
Когда вы chan Гед некоторые свойства и хотите перенастроить log4j2, вы должны сделать этот призыв:
final LoggerContext ctx = (LoggerContext) LogManager.getContext(false);
ctx.reconfigure();
Надежда это помогает
log4j2 непосредственно, без каких-либо SLF4J? –
@SotiriosDelimanolis - Да, это было целью. –
Чистая программная конфигурация также отсутствовала в журнале и до недавнего времени. См. Http://stackoverflow.com/questions/22335441/configure-logback-to-defer-to-java-configuration-aka-plain-java-configuration-of. , В этой записи SO есть ссылка log4j2, из-за которой я никогда не мог загружать log4j2 с помощью моего кода инициализации, но последний logback позволит вам управлять процессом init. –
