SLF4J Tutorial

What is SLF4J?

SLF4J stands for Simple Logging Facade for Java. It provides a simple abstraction of all the logging frameworks. It enables a user to work with any of the logging frameworks such as Log4j, Logback, JUL (java.util.logging), etc. using single dependency.

This SLF4J tutorial is based on the latest SLF4J 2.1.0-alpha1 version.

Features of SLF4J

Following are the salient features of SLF4J −

• Using SLF4J framework, you can migrate to the desired logging framework at the time of deployment.

• Slf4J provides bindings to all popular logging frameworks such as log4j, JUL, Simple logging and, NOP. Therefore, you can switch to any of these popular frameworks at the time of deployment.

• SLF4J provides support to parameterized logging messages irrespective of the binding you use.

• Since SLF4J decouples application and logging framework, you can easily write applications independent of logging frameworks. You need not bother about the logging framework being used to write an application.

• SLF4J provides a simple Java tool known as migrator. Using this tool, you can migrate existing projects, which use logging frame works like Jakarta Commons Logging (JCL) or, log4j or, Java.util.logging (JUL) to SLF4J.
