How -Dlogging.level JVM argument is handled in spring boot, spring cloud

Question

I have a spring cloud application, which under the covers uses spring boot.

In the bootstrap phase of the app I am using some classes from the apache commons config library under: org.apache.commons.configuration

My application is started with this flag per the spring docs:

-Dlogging.level.org.apache.commons.configuration=INFO

Despite this, i am still getting DEBUG level logs emitted during the bootstrap phase of spring....

I am lost as to how to properly specify the log level of INFO specified for the bootstrap phase of spring boot.

What does the rest of your logging configuration look like? Also, what are you using to log (i.e. log4j2, logback, etc.)? — Dovmo, Aug 12 '18 at 21:42
Whatever comes w/ spring-boot, spring-cloud, slf4j w/ logback — bitsofinfo, Aug 13 '18 at 05:53
But how come you're seeing any DEBUG level messages at all? Did you set the root logging level to DEBUG? — Dovmo, Aug 13 '18 at 19:00
set root logger is DEBUG, and `-Dlogging.level.org.apache.commons.configuration=INFO` — bitsofinfo, Aug 16 '18 at 06:46

Ensure you are not setting debug=true in application properties or not passing --debug flag to the application.

In application.properties set:

debug=false

The configuration of spring boot has a specific order, so probably somewhere in the application or bootstrap configuration files the logging level is configured to DEBUG. Source: https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html

I understand, however this system level property to the JVM is `-Dlogging.level.org.apache.commons.configuration=INFO` yet that is eminating DEBUG logs – bitsofinfo Aug 16 '18 at 06:47
