Spring Boot Logging & Swagger Integration | Complete Guide

🚀 Spring Boot - Adding Logs & Swagger Integration 🚀

In this video, we take our Spring Boot application to the next level by integrating logs for better debugging and adding Swagger for seamless API documentation. Logging helps track API activity, while Swagger provides an interactive UI to test and document REST APIs.

📌 Topics Covered in This Video:
✅ Why Logging Is Important in Spring Boot – Debugging & monitoring.
✅ Adding Logs Using SLF4J & Logback – Best practices for log levels.
✅ Configuring @Slf4j for Logging in Spring Boot – Clean & efficient logs.
✅ Understanding Log Levels (INFO, DEBUG, ERROR, WARN) – When to use what.
✅ Setting Up Swagger in Spring Boot – Interactive API documentation.
✅ Customizing Swagger UI – Improving API documentation experience.
✅ Testing APIs with Swagger – Making API calls directly from Swagger UI.
✅ Best Practices for Logging in Spring Boot Applications – Writing structured logs.

🛠️ Step-by-Step Guide to Logging & Swagger Integration:
1️⃣ Add SLF4J & Logback Dependencies – Use Maven/Gradle to include logging support.
2️⃣ Use @Slf4j Annotation – Simplify logging with Lombok’s @Slf4j.
3️⃣ Implement Logging in Controller & Service Layers – Track API activity.
4️⃣ Set Up Log Levels in application.properties – Control logging verbosity.
5️⃣ Add Swagger Dependencies (springdoc-openapi) – Enable API documentation.
6️⃣ Configure Swagger UI in Spring Boot – Customize Swagger for a better experience.
7️⃣ Test REST APIs Using Swagger UI – Execute GET, POST, PUT, DELETE requests easily.
8️⃣ Improve API Documentation – Add descriptions, parameters, and responses.

🔥 Why Use Swagger?
Swagger makes API testing easier by providing an interactive UI for developers to explore, test, and document endpoints effortlessly. It enhances API usability and reduces dependency on external tools like Postman.
