Simple Logging Facade for Java (SLF4J)

The Simple Logging Facade for Java or (SLF4J) serves as a simple facade or abstraction for various logging frameworks, e.g. java.util.logging, log4j and logback, allowing the end user to plug in the desired logging framework at deployment time.

Before you start using SLF4J, we highly recommend that you read the two-page SLF4J user manual.
