Log4j1.x 迁移到 log4j2 java

Question

I have upgraded log4j1.x version to log4j2.17, I observed that some of new logs are printing on my console/server.log which might be from other jars I am using (eg updating server status in database)

How can I restrict stdout in my console or server.log

I have added console appender in my log4j2.xml

While this looks like a bad idea - you would want important logs from dependencies to be a part of your log for debugging issues, here is the way to do it.

In log4j.properties file, you can set the root logger to ERROR. Then for the your own application, you can override the now default ERROR to INFO/DEBUG.

log4j.rootLogger=ERROR, stdout
log4j.X.Y.Z=DEBUG
