How do I integrate SLF4J with my Java application?

To integrate SLF4J, you need to add the SLF4J API and a binding implementation to your project. Are you using Maven or Gradle?

I'm using Maven. What dependencies do I need?

For Maven, add the following dependencies to your pom.xml:

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.7.30</version>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-simple</artifactId>
    <version>1.7.30</version>
</dependency>

This will include the SLF4J API and a simple binding.

What if I want to use Logback instead of the simple binding?

If you want to use Logback, replace the slf4j-simple dependency with:

<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.2.3</version>
</dependency>

Logback is a more powerful logging framework.
