Spring Boot FAQ: Top Questions

Spring Boot uses Apache Commons Logging for internal logging and defaults to Logback for runtime logging. It supports logging configuration using application.properties, logback.xml, or log4j2.xml.

📘 Default Behavior:

• Outputs logs to console.
• Logback is used as the default logging framework.
• Supports log level configuration per package or class.

📥 Example:

logging.level.org.springframework=DEBUG
logging.level.com.myapp=INFO

🏆 Expected Output:

DEBUG logs from Spring and INFO logs from your app appear in console.

🛠️ Use Cases:

• Debugging issues in development.
• Monitoring logs in production environments.
