How can I implement logging in Java microservices?

You can use frameworks like SLF4J with Logback or Log4j for logging in Java microservices. Would you like a code example?

Yes, please provide a code example using SLF4J and Logback.

Sure! First, add the dependencies to 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>

Then, you can create a logger in your service class:

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class MyService {
    private static final Logger logger = LoggerFactory.getLogger(MyService.class);

    public void performAction() {
        logger.info("Action performed");
    }
}

How do I configure Logback for different environments?

You can create different logback.xml files for each environment and use the -Dlogback.configurationFile system property to specify which one to use when starting your application.
