Spring Batch for Real-World Practice

This is a hands-on introductory course where you can learn everything from Kafka installation to Producer/Consumer message transmission by following along with Spring Boot. Rather than focusing on complex theories, you will quickly understand the basic flow of Kafka—how messages are published and subscribed to through Topics—by writing and executing actual code yourself. It is suitable for beginner and junior backend developers who are integrating Kafka for the first time.

This course is for those who want to learn DDD but feel lost on "how to apply it to a real project." In this course, we will implement DDD design from start to finish by **building an actual ordering system** based on Spring Boot. The focus is not on simple theory, but on "structures and code that can be used immediately in practice." After taking this course, you will be able to: ✔ Design DDD-based projects on your own ✔ Implement professional-level structures yourself

Learn the SAGA transaction management technique for maintaining data consistency in distributed environments through a hands-on approach.

I highly recommend Spring AI to developers using Spring Boot and React, as well as those considering the introduction of AI systems in corporate environments. This course goes beyond a simple introduction to libraries; it helps you understand the core concepts and internal structure of Spring AI, and strengthens your practical implementation skills through various hands-on examples. The course is based on Spring AI version 1.1.x and provides continuous technical support and expansion strategies to ensure you can adapt to future version upgrades. Furthermore, we expand the practical value of Spring AI technology by utilizing MCP (Model Context Protocol) to achieve cross-domain context integration, AI linkage in distributed environments, and AI architecture design suitable for enterprise environments. With the goal of building AI systems that can actually be deployed in corporate settings, this will serve as a practical guide that balances theory and hands-on experience.
