Why calling LoggerFactory.getLogger(…) every time is not recommended?

Question

I\'ve read tons of posts and documents (on this site and elsewhere) pointing that the recommended pattern for SFL4J logging is:

public class MyClass {
    fi         


        

Answer 1

The logger objects are surely reused, so no extra instantation is going to happen either way. The bigger problem I see is that your file/line number info will be useless, since the logger will always faithfully log that each message was issued from class LoggerWrapper, line 12 :-(

OTOH SLF4J is already a wrapper facade to hide the specific logging framework used, allowing you to freely change between different logging implementations. Therefore I see absolutely no point in hiding that behind yet another wrapper.
