How do I integrate SLF4J logging in my Java application?

To integrate SLF4J, you need to add the SLF4J API and a logging implementation like Logback to your project.

What dependencies do I need to add to my Maven project?

You need to add the following dependencies in your pom.xml:

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.7.30</version>
</dependency>
<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.2.3</version>
</dependency>

How do I configure Logback for logging?

You can configure Logback using a logback.xml file in your resources directory. Here's a simple example:

<configuration>
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss} %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>
    <root level="debug">
        <appender-ref ref="STDOUT" />
    </root>
</configuration>
