Set logging level for mongodb java driver 3.0

Question

I'm including the mongo java 3.0 driver in a plugin for an application that uses log4j2. I can't modify the log4j2.xml file, but I need to be able to set the logging level for the mongo driver.

This would have worked if it was using the native java logger:

Logger mongoLogger = Logger.getLogger("org.mongodb.driver");
mongoLogger.setLevel(Level.SEVERE);

But this won't affect log4j2.

I don't want to affect levels for all loggers, just the mongo one.

Answer 1

如果已在配置中命名了Log4j2记录器，则可以使用log4j2 JMX界面来设置log4j2记录器的日志级别。
