Developing the Presentation Tier with Spring Boot and REST

Modern web applications rely on a robust and scalable presentation tier to handle user requests and deliver data efficiently. This text-only course guides you through the process of building this layer using Spring Boot and RESTful controllers, bridging the gap between client requests and backend business logic. You will learn how to structure APIs, process data, and connect your endpoints to database services using modern Java standards. Starting with foundational web architecture and HTTP basics, you will quickly progress to designing clean, maintainable endpoints. The curriculum covers essential modern practices including request validation, structured error handling, and type-safe data transfer objects (DTOs) to ensure your APIs are secure, resilient, and ready for production environments. What you'll learn: - Understand the core principles of RESTful architecture and the MVC pattern in Spring - Configure Spring controllers to handle diverse HTTP methods and request formats - Integrate presentation endpoints with underlying business services and databases - Apply robust input validation and global exception handling to your APIs - Utilize modern Java features like records and type hints for cleaner data transfer - Practice building and testing endpoints using structured written walkthroughs This course is structured to take you from a basic understanding of web requests to implementing a fully functional, secure presentation tier. Each chapter focuses on conceptual clarity followed by clear, step-by-step code implementations and design patterns. This course is designed for beginner-to-intermediate Java developers, software engineering students, and backend enthusiasts who want to master API development. No prior experience with Spring is required, though a basic understanding of Java programming is recommended.
