Spring Boot 4 for Absolute Beginners: Build real Java web applications from your very first line of code

By: Panda, Rajkumar

Start from zero. Finish with a real application.

You need to know basic Java. That is genuinely all. Everything else - HTTP, Maven, SQL, Docker, testing - is explained the first time it appears, in plain words, with no assumed background.

You will build one small application and grow it across fifteen chapters: a web API, then a real database, then caching, security, messaging, monitoring and deployment. By the end you will have written the kind of service that runs in production.

What you will learn

Your first project, and what the framework is really doing behind the annotations
REST APIs with validation, error handling and versioning
SQL and NoSQL data access, with your queries written for you
Testing at every level, against real databases in containers
Security, messaging, metrics, tracing and native images
API gateways, circuit breakers, and building your own Spring Boot starter

Every listing was compiled and run against Spring Boot 4.1.1 on Java 25 before it was printed - with real PostgreSQL, MongoDB, Redis, RabbitMQ and Kafka. The log output, JSON responses and error messages in this book came from actual program runs, not from imagination.

Version 4 renamed a great many things. If you have read older tutorials, some of what you remember is now wrong. This book teaches the new way from the first page.
