Set Logging Level in Spring Boot via Environment Variable

Question

Should it be possible to set logging levels through environment variables alone in a Spring Boot application?

I don\'t want to use application.properties

Answer 1

This is just an idea, but did you try setting

_JAVA_OPTIONS=-Dlogging.level.org.springframework=TRACE?

Theoretically, this way -Dlogging.level.org.springframework=TRACE will be passed as default JVM argument and should affect every JVM instance in your environment.
