to do log4j loggingIn addition to the above benefits, I think there is a caveat that, in order to use SLF4J, you need not only to include the SLF4J API jar package, such as Slf4j-api-1.6.1.jar, but also the relevant jar package, depending on the Log class library you use in the background. If you want to use SLF4J with log4j, simple Logging facade for Java, you need to include the following jar package in
