I am trying to debug an issue with Jackson and I would like to see log entries from com.fasterxml.jackson. Unfortunately this solution How to see org.codehaus.jackson log messages - using logging.properties doesn't do anything for me because Spring Boot 2 uses the updated com.fasterxml.jackson package, and I'm using logback for my log config. I am using Spring Boot 2.1.0.RELEASE which uses Jackson 2.9.

I have the following in logback-spring.xml

<logger name="com.fasterxml.jackson" level="TRACE" additivity="false">
    <appender-ref ref="CONSOLE" />
</logger>

(I have tried with additivity set to true as well)

and the following in application.properties

logging.level.com.fasterxml.jackson=TRACE

but nothing is showing up in my logs for Jackson.

Worth checking does it really logs ? Just checked ObjectMapper. It does not have any logger. – bittu Nov 21 '18 at 17:52
@bittu Hmmm I hadn't considered that. That would be unfortunate. – secondbreakfast Nov 21 '18 at 18:09
