Failed to bind properties under logging.level.* or someproperty.*=some_value

Question

After i migrated from Spring boot 1.5 to 2.x i have the below problem:

APPLICATION FAILED TO START

Description:
Failed to bind properties under logging.level to java.util.Map<java.lang.String, java.lang.String>:

Reason: No converter found capable of converting from type [java.lang.String] to type [java.util.Map<java.lang.String, java.lang.String>]

Action:

Update your application's configuration

In properties I have

logging.level.*=debug

It works if I go back to version 1.5.x Can anyone point me in the right way?

UPDATE : The same problem happens when I use

someproperty.*=some_value

That means the .*= is not supported in SpringBoot 2.0 ?

Answer 1

You need to explicitly mention logger name, if you are using SpringBoot 2.x.x, which you can notice when you compare documentation of both the versions.

SpringBoot 2.0.0

... using logging.level.<logger-name>=<level> where level is one of TRACE, DEBUG, INFO, WARN, ERROR, FATAL, or OFF. ...

Eg:

logging.level.root=WARN

SpringBoot 1.5.4

... logging.level.*=LEVEL where 'LEVEL' is one of TRACE, DEBUG, INFO, WARN, ERROR, FATAL, OFF...

Eg:

logging.level.*=WARN
