Spring Security OAuth 2 Tutorial - 6 : Microservices Sample Project Setup

Part 6 of a Spring Security OAuth 2 tutorial series introduces a sample microservices project used throughout the series. The project consists of four components: a Keycloak authorization server, a messages-webapp (Spring MVC client using Authorization Code Flow), a messages-service (REST API resource server), and an archival-service (acting as both resource server and client using Client Credentials Flow). The post outlines each service's responsibilities, API endpoints, and role-based access rules, and covers how to export and import Keycloak realm configuration via Docker for reproducible setup.
