There are a lot of explanations, how to turn on the Auto-Configuration-Report offered by Spring-Boot to debug the configuration of ones app.
For an good example take a look at this little Spring boot troubleshooting auto-configuration guide.
But most often, when I want to see the Auto-Configuration-Report, I am running my app via mvn:spring-boot:run.
And, unfortunatly, none of the guids you can find by google tells you, how to turn on the Auto-Configuration-Report in this case.
Hence, I hope I can help out, with this little tip.
How To Turn On The Auto-Configuration-Report When Running mvn spring-boot:run
The report is shown, if the logging for org.springframework.boot.autoconfigure.logging is set to DEBUG.
The most simple way to do that, is to add the following line to your src/main/resources/application.properties:
logging.level.org.springframework.boot.autoconfigure.logging=DEBUG
I was not able, to enable the logging via a command-line-switch.
The seemingly obvious way to add the property to the command line with a -D like this:
mvn spring-boot:run -Dlogging.level.org.springframework.boot.autoconfigure.logging=DEBUG
did not work for me.
If anyone could point out, how to do that in a comment to this post, I would be realy grateful!
