Building REST APIs with Spring Boot and @GetMapping

Every modern web application and mobile app relies on backend services to fetch and display data. If you want to build robust backend systems, understanding how to handle HTTP GET requests is your very first step. This text-based course guides you through the fundamental concepts of RESTful web services using Spring Boot, teaching you how to expose data safely and efficiently to the web. You will start by mastering foundational HTTP concepts and Spring annotations before moving on to practical implementation patterns. By reading through clear, structured explanations and analyzing real-world code snippets, you will gain the confidence to build and configure your own API endpoints. What you will learn: Understand the core principles of REST architecture and how HTTP GET requests function; Configure @GetMapping annotations to route web requests to your Java controller methods; Create and structure plain old Java objects (POJOs) to represent your application data; Serialize Java objects and collections automatically into clean, standardized JSON payloads; Apply modern Spring Boot patterns to manage application state and structure clean controller code. This course starts with essential terminology and the basics of web controllers, then guides you step-by-step through creating endpoints that return single objects and lists of data. This course is designed specifically for beginners who have a basic understanding of Java and want to transition into backend web development.
