The default settings of the sample application produce a clean log that contains only important informational messages from the REST API service user perspective. Warnings and errors will be displayed. But information for developers are not included by default.
In order to see debugging messages that are useful for developers, a debugging profile needs to be enabled.
This profile is called debug.
You can pass it as a command line argument --spring.profiles.include=debug when you start the JAR. For example:
java -jar build/libs/*.jar --spring.config.additional-location=file:./config/local/application.yml --spring.profiles.include=debug
Or with Gradle:
./gradlew bootRun --args='--spring.config.additional-location=file:./config/local/application.yml --spring.profiles.include=debug'
There is a profile called diag that is enabled in config/local/application.yml.
This profile enables all Spring Actuator endpoints that you can see at: https://localhost:10080/actuator
