Overview of this book

Keep up with the fast-paced tech landscape with Software Architecture with Spring, your practical guide to making strategic architectural decisions that align seamlessly with your business objectives. Drawing from Wanderson's decades of experience, you'll journey through the complete software development lifecycle—from initial requirements gathering, through development and testing, to production deployment. You'll get hands-on with the evolution of an auction system, exploring its transformation through multiple architectural styles. You’ll discover how you can effectively transform a monolithic system into microservices using proven patterns and practices. As you progress, you’ll master advanced architectural paradigms such as Event-Driven Architecture, Filter-and-Pipeline Architecture, and Serverless Architecture.

Implementing OAuth2 with Spring Authorization

It’s time to put our learning into practice. We will use Spring Authorization Server, a framework that offers OAuth2 and OIDC authentication and authorization capabilities for Spring-based applications. It issues clients with access tokens, refresh tokens, and ID tokens following OAuth2 flows.

Online auction case study

As our online auction application grows, we now face a new challenge: third-party clients and external applications are requesting access to our product catalog through APIs. Exposing the product API requires careful consideration of security measures. Relying solely on traditional API keys or basic authentication is no longer sufficient.

System definition and mission

We will implement a robust authentication and authorization mechanism to securely expose our product API to external clients. We will introduce a new component to enforce access control: the authorization server.

The authorization server...
