Feeling intimidated by backend development, Java frameworks, or all those confusing words like controllers, beans, repositories, APIs, testing, and security?
Spring Boot 4 and Spring Framework 7 for Beginners was written to make modern Java backend development feel clear, practical, and achievable-even if you are just starting out. Instead of overwhelming you with scattered theory or unexplained code snippets, this friendly guide walks you step by step through building a real REST API from the ground up.
You will learn by creating TaskFlow API, a practical task management backend project that grows with you throughout the book. Each chapter introduces new concepts slowly, explains why they matter, and helps you build confidence through small, meaningful wins.
Mistakes are treated as part of learning-not failure. Whether your app refuses to start, a test fails, or an endpoint returns the wrong response, this book helps you understand what is happening and keep moving forward.
