SLF4J, To avoid writing LoggerFactory.getLogger(MyClassName.class) every time

Question

I am writing a web application in Java and using SLF4J for logging.

I'm becoming tired of writing the below line for every class that uses logging:

private static final Logger logger = LoggerFactory.getLogger(ThisClassName.class);

To avoid redundant codes, I am thinking something like

interface Loggable {
    Logger logger();
}

and each class can just implement this interface then some magic like AOP inserts the LoggerFactory part.

Has anyone implemented this or knows how to achieve this?

Thanks!

Answer 1

Are you using eclipse? If so, why not just use a code template with a keyword like "logger" and the following template for it:

${:import(org.slf4j.LoggerFactory, org.slf4j.Logger)}
private static final Logger LOGGER = LoggerFactory.getLogger(${enclosing_type}.class);

This way you would just type "logger", hit shift+space and you are done.

Answer 2

Are you using CDI? if so, create a producer method and then @Inject the logger to any CDI enabled class.

@Produces Logger createLogger(InjectionPoint injectionPoint) { 
    return Logger.getLogger(injectionPoint.getMember().getDeclaringClass().getName()); 
}
