我可以将 Spring 引导日志记录设置从 application.properties 文件移到未跟踪的文件中吗？

Question

I am working on building a SpringBoot app with my workmates. We all have different preferred logging levels for the app. We have been battling back and forth with each other's logging changed to application.properties. Is there a way to move all of the logging.level.* stuff out of that application.properties file and into a ~logging.properties file or something? That way we can add that file to the.gitignore and not track that file so we can each leave our logging alone. We are using Java annotations and not xml btw.

I've tried adding @PropertySource("classpath:logging.properties") to the application file, but I read somewhere that the logging gets setup early on in the init process and this won't work. I tried it anyway and it doesn't work (so confirmed I guess).

I can't believe there's isn't more info on this out there.. I'd imagine the members of a dev team each want their own custom level of logging and don't want to keep stepping on each other's toes/commits.

You can just override it using a command line property. The fallback strategy will take command line -D args as the highest overriding priority.

I would recommend to have logback.xml file inside resources/ with some defaults that works for everyone (more likely to the application in question) and then you can provide --logging.config=/path/to/your/very/custom/logback.xml file whenever you start the application locally .

That should work for everyone.
