Building REST Controllers in Spring Boot

Modern web development relies on clean, predictable APIs to connect front-end applications with server-side data. Building these APIs requires a solid grasp of how to map incoming HTTP requests to backend logic and return structured responses. This course guides you through the foundational concepts of RESTful architecture and teaches you how to implement reliable endpoints from scratch. You will start by understanding basic HTTP methods, status codes, and routing principles before writing any code. What you will learn: - Understand the core principles of REST architecture and how resources are represented, - Map HTTP GET, POST, PUT, and DELETE requests to controller methods, - Extract request data using path variables, query parameters, and request bodies, - Return structured JSON responses with appropriate HTTP status codes, - Handle API exceptions gracefully and return standardized error messages, - Apply modern security practices and input validation to protect your endpoints. This text-based program begins with key API definitions and architectural patterns before moving into step-by-step implementation scenarios, ensuring you build a strong conceptual framework. This course is designed for beginner backend developers and software engineers who have a basic understanding of Java or Spring Boot but are new to building web APIs. No prior API development experience is required. Start reading today to build and deploy your first secure REST endpoints.
