spring-boot default log location

Question

In a spring-boot application I can specify a custom log file with

java -jar spring-boot-app.jar --logging.file=/home/ubuntu/spring-boot-app.log

Answer 1

By default Spring Boot does not output logs to any file. If you want to have logs written in a file (in addition to the console output) then you should use either of logging.file or logging.path properties (not both).

In application.properties, just set:

logging.file=/home/ubuntu/spring-boot-app.log

This will create a spring-boot-app.log file under /home/ubuntu.
