How can I implement JSON logging in a Java application?

You can use libraries like Logback or Log4j2 to implement JSON logging in Java. Would you like a code example?

Yes, please provide a code example using Logback.

Sure! First, add the Logback dependency to your project. Then, configure the logback.xml file to use JSON encoder. Here's a simple example:

<configuration>
    <appender name="JSON" class="ch.qos.logback.core.FileAppender">
        <file>logs/app.json</file>
        <encoder class="net.logstash.logback.encoder.LoggingEventCompositeJsonEncoder">
            <providers>
                <timestamp />
                <logger />
                <thread />
                <level />
                <message />
            </providers>
        </encoder>
    </appender>
    <root level="INFO">
        <appender-ref ref="JSON" />
    </root>
</configuration>

What dependencies do I need to include for Logback?

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

<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.2.3</version>
</dependency>
<dependency>
    <groupId>net.logstash.logback</groupId>
    <artifactId>logstash-logback-encoder</artifactId>
    <version>6.6</version>
</dependency>
