REST Architecture for Java Web Services

Building scalable backend services requires a deep understanding of how systems communicate over the web. This course provides a clear, text-based introduction to REST architecture, guiding you from fundamental HTTP concepts to designing production-ready APIs in Java. You will learn how to structure resources, manage state, and handle data exchange efficiently using modern industry standards. By the end of this course, you will be able to design, document, and implement secure, stateless RESTful APIs using the Spring framework. What you'll learn: Understand core REST constraints, resource naming conventions, and HTTP methods; Design clean API endpoints with appropriate status codes and error payloads; Implement stateless communication patterns and manage data serialization; Build RESTful endpoints using modern Spring Boot conventions and dependency injection; Apply basic security practices and handle input validation for incoming requests; Practice writing unit tests for your API endpoints to ensure reliability. We begin with essential web service terminology and architectural constraints before moving on to practical API design patterns, database integration, and modern testing workflows. This course is designed for beginner backend developers, students, and Java programmers looking to transition into web service development. No prior experience with REST or API design is required.
