- Apply API design concepts to build fully functional services using popular frameworks like Spring Boot

- Purchase of the print or Kindle book includes a free PDF eBook

Book Description:

REST powers the modern web, yet developers grapple with architectural missteps that lead to poorly designed REST endpoints, inadequate error handling, security vulnerabilities, and maintenance headaches. Written by five software engineering and Java experts, Mastering RESTful Web Services with Java helps you overcome these pitfalls with a deep, practical understanding of REST architecture, HTTP protocols, and modern API design principles.

This hands-on guide introduces foundational concepts based on Roy Fielding's principles and the Richardson Maturity Model and shows you how to apply them in your API development projects. You'll build a Product API from scratch, progressively enhancing it with documentation, versioning, and security features, and then advance to creating an Order Management API that interacts with the Product API, while implementing advanced testing and performance optimization techniques. Each chapter delivers step-by-step explanations and practical examples, ensuring you develop production-ready skills that translate directly to your daily work.

By the end of the book, you'll be ready to deliver production-grade RESTful services and become the API expert your team turns to for critical application development projects.

What You Will Learn:

- Design clean, modular REST APIs that support real-world business workflows

- Implement secure authentication and authorization flows using modern identity standards

- Deploy your application to the cloud with strategies that ensure reliability, elasticity, and cost-efficiency

- Use the OpenAPI specification to define precise contracts and promote consumer-driven API development

- Leverage Java records and virtual threads to write concise, scalable, and concurrent service logic

- Apply structured testing techniques to validate behavior, resilience, and security across your API layers

Who this book is for:

This book is for mid-to-senior level backend Java developers looking to improve the quality and performance of their REST APIs. Whether you're optimizing existing APIs or launching a greenfield project, the ideas shared here will enhance your development practice. Additionally, tech leads and architects looking to sharpen their API design skills and master advanced Java API development techniques will find this book useful.
