API Documentation with Spring REST Docs and Spring Boot

Keeping API documentation accurate and up to date is a constant struggle for development teams. This course teaches you how to automate this process by generating reliable, test-driven documentation directly from your Spring Boot codebase. You will learn to establish a single source of truth that ensures your docs never fall out of sync with your production code. By completing this text-based course, you will transform how you document APIs, moving from manual, error-prone updates to automated, test-validated portals. You will understand how to leverage Asciidoctor to design professional, searchable API portals that your team and external consumers will love. What you'll learn: - Understand the core concepts of test-driven documentation and why it prevents outdated API portals - Configure Spring REST Docs within a Spring Boot application using Maven or Gradle - Write MockMvc and WebTestClient tests that automatically generate accurate documentation snippets - Structure and customize your API portal using Asciidoctor syntax and layouts - Document modern API patterns, including reactive endpoints, request/response headers, and error payloads - Integrate documentation generation into your continuous integration (CI) pipelines We start with the foundational concepts of API documentation, establishing a solid understanding of Spring REST Docs architecture. From there, you will progress through hands-on testing techniques, configuring Asciidoctor templates, and building a fully functional, self-updating API portal. This course is designed for beginner to intermediate Java developers and backend engineers who want to automate their documentation workflows. No prior experience with Spring REST Docs or Asciidoctor is required, though a basic familiarity with Spring Boot and writing unit tests is helpful.
