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

In spring-boot 2.0.0, adding --trace works. For instance java -jar myapp.jar --debug or java -jar myapp.jar --trace
