Set root logging level in application.yml

Question

I used an application.properties with Spring Boot (1.3 M1) and started to translate it into a yaml file because it grew more and more complex.

But I have problems translating this into yaml:

logging.level.*=WARN
logging.level.com.filenet.wcm=ERROR
logging.level.de.mycompany=DEBUG

The last two lines are easily translated into this:

logging:
    level:
        com.filenet.wcm: ERROR
        de.mycompany: DEBUG

But how to add the values for the root logging level ? These two approaches failed:

Failed approach 1:

logging:
    level: WARN
        com.filenet.wcm: ERROR
        de.mycompany: DEBUG    

Failed approach 2:

logging:
    level: 
        star: WARN
        com.filenet.wcm: ERROR
        de.mycompany: DEBUG    

I read the docs, searched stackoverflow and googled but did not find an example for a valid syntax.

Answer 1

You can use ROOT to configure the root logging level:

logging:
  level:
    ROOT: DEBUG
