Improve the logging documentation [SPR-15170]

[spring-issuemaster]

Matt Sicker opened SPR-15170 and commented

The current logging documentation references Log4j 1.x which is EOL. I'd like to add some updated docs for the logging section for Log4j 2.x and integration with SLF4J, a commonly used logging facade outside of this specific project.

I have a pull request here: #1279

Thanks for the PR!

I polished it a bit to remove log4j 1.x altogether. There's no need to keep a section for if it's EOL anyway.

Juergen Hoeller I haven't backported this to 4.3.x yet. I guess we should probably keep the section on log4j 1.x there still? I can rework the pr for 4.3.x if you want. Let me know.

As mentioned in the PR, make sure to include that Log4j 2.3 is the last supported release for Java 6. Thanks!

For 4.3.x, let's have a note on Log4j 1.x, mentioning its EOL. And indeed, let's also mention Log4j 2.3 as the last Java 6 compatible release there.
