Spring Loggin not showing in the console

Question

i am struggling with Spring Boot Loggin. I am not able to print log.info or log.error on my console. Here is my pom.xml file and application.properties also. I am wondering why is this behaviour happening as I do not have any specific declarations in my pom file.

application.properties

Firts of all ! REMOVE THE PASSWORD from the application.properties — Zorglube
Hello, Zorglube, I have tried with loggin.level and etc., also with hibernate properties, but nothing is helping. Also the system.out.println() is not working. I am not able to debug anything. Have removed the pass!!! THANKS! Any other suggestions? — mzhack
Did you tried using Slf4j, I'm usiing it with Spring boot it work perfectly fine. — Zorglube

Enable logging in the application.properties

logging.level.root=WARN
logging.level.com.jgeekmz=DEBUG

logging.pattern.console=%clr(%5p) [%logger{0}] %m%n
