Step 1: Create new maven project ‘slf4j-commons-logging-demo’.
Step 2: Update pom.xml with maven dependencies.
pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.sample.app</groupId>
<artifactId>slf4j-commons-logging-demo</artifactId>
<version>1</version>
<dependencies>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-jcl</artifactId>
<version>1.7.31</version>
</dependency>
</dependencies>
</project>
Step 3: Define hello world application.
HelloWorld.java
package com.sample.app;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class HelloWorld {
public static void main(String args[]) {
Logger logger = LoggerFactory.getLogger(HelloWorld.class);
logger.info("Welcome to SLF4J logging");
}
}
