In this detailed Resource page, we feature an abundance of Java SLF4J Tutorials!
SLF4J (Simple Logging Facade for Java) provides a Java logging API by means of a simple facade pattern. The underlying logging backend is determined at runtime by adding the desired binding to the classpath and may be the standard Sun Java logging package java.util.logging, log4j, logback or tinylog.
The separation of the client API from the logging backend reduces the coupling between an application and any particular logging framework. This can make it easier to integrate with existing or third-party code or to deliver code into other projects that have already made a choice of logging backend.
SLF4J was created by Ceki Gülcü as a more reliable alternative to Jakarta Commons Logging framework. Research in 2013 on 10,000 GitHub projects found that the most popular Java library is SLF4J, with 30.7% of projects using it.

Java SLF4J Tutorials – Functions
Examples based on the Java SLF4J
- Slf4j Format String Example
In this example, we are going to see how String log messages can be constructed in SLF4J with parameter substitution.
- Slf4j Commons Logging Example
In this example, we are going to see how SLF4J fares vis-à-vis Apache Commons Logging.
- SLF4J Markers example
In this example, we shall show you how to use Markers with SLF4J.
- SLF4J Logging Levels Example
This post is about the various logging levels available in SLF4J and how to extend it with Marker interface. This post utilizes Logback as the logging implementation for our examples.
- Slf4j Configuration File Example
In this example, we are going to see how to configure Slf4j with some popular logging frameworks. SLF4J is a facade or an abstraction layer over various logging frameworks.
- Solving Failed to load class “org.slf4j.impl.StaticLoggerBinder” Error
The Simple Logging Facade for Java (SLF4J) serves as a simple facade or abstraction for various logging frameworks (e.g. java.util.logging, logback, log4j). This allows the end user to plug in the desired logging framework at deployment time.
- Slf4j Spring Boot Example
In this example, we are going to learn how to use SLF4J in Spring projects with an example of Spring Boot application.
