Mastering RESTful Web Services with Java

🌐 یادگیری طراحی RESTful API با جاوا – از اصول پایه تا تکنیک‌های پیشرفته برای احراز هویت، نسخه‌بندی، مدیریت خطا، امنیت، تست، بهینه‌سازی عملکرد و موارد بیشتر.

🔑 ویژگی‌های کلیدی:

• کشف اصول معماری ضروری برای ساخت REST APIهای مقاوم و قابل تطبیق
• کسب بینش عملی برای بهبود عملکرد و امن‌سازی نقاط انتهایی از طریق مطالعات موردی واقعی
• پیاده‌سازی مفاهیم طراحی API برای ساخت سرویس‌های کاملاً عملی با فریم‌ورک‌های محبوب مانند Spring Boot

📖 توضیح کتاب:

REST قلب وب مدرن است، اما توسعه‌دهندگان اغلب با اشتباهات معماری مواجه می‌شوند که منجر به نقاط انتهایی ضعیف، مدیریت ناقص خطاها، آسیب‌پذیری‌های امنیتی و مشکلات نگهداری می‌شود. این کتاب، نوشته‌ی پنج کارشناس نرم‌افزار و جاوا، به شما کمک می‌کند با درک عمیق و عملی معماری REST، پروتکل‌های HTTP و اصول طراحی مدرن API، از این مشکلات اجتناب کنید.

این راهنمای عملی، مفاهیم پایه‌ای مبتنی بر اصول Roy Fielding و Richardson Maturity Model را معرفی می‌کند و نشان می‌دهد چگونه آن‌ها را در پروژه‌های توسعه API خود اعمال کنید. شما از صفر یک Product API می‌سازید و به تدریج آن را با مستندسازی، نسخه‌بندی و ویژگی‌های امنیتی ارتقا می‌دهید، سپس به توسعه‌ی Order Management API می‌پردازید که با Product API تعامل دارد و تکنیک‌های پیشرفته‌ی تست و بهینه‌سازی عملکرد را پیاده‌سازی می‌کند. هر فصل شامل توضیحات گام‌به‌گام و مثال‌های عملی است تا مهارت‌های آماده‌ی تولید را در شما پرورش دهد.

🔑 آنچه خواهید آموخت:

• طراحی REST APIهای تمیز و مدولار که جریان‌های کاری واقعی کسب‌وکار را پشتیبانی کنند
• پیاده‌سازی جریان‌های احراز هویت و مجوزدهی امن با استفاده از استانداردهای مدرن
• استقرار برنامه در Cloud با استراتژی‌هایی که اطمینان، انعطاف‌پذیری و هزینه-کارآمدی را تضمین می‌کنند
• استفاده از OpenAPI برای تعریف قراردادهای دقیق و ترویج توسعه API مبتنی بر مصرف‌کننده
• بهره‌گیری از Java records و virtual threads برای نوشتن کدهای مقیاس‌پذیر، همزمان و مختصر
• اعمال تکنیک‌های تست ساختاری برای اعتبارسنجی رفتار، پایداری و امنیت در تمام لایه‌های API

👥 مخاطبان کتاب:

این کتاب برای توسعه‌دهندگان جاوای Backend با سطح متوسط تا پیشرفته طراحی شده است که می‌خواهند کیفیت و عملکرد REST APIهای خود را بهبود دهند. چه در حال بهینه‌سازی APIهای موجود باشید و چه در حال شروع یک پروژه‌ی جدید، مفاهیم ارائه‌شده مهارت توسعه شما را ارتقا می‌دهد. همچنین Tech Leadها و معماران نرم‌افزار که به دنبال تقویت مهارت‌های طراحی API و تسلط بر تکنیک‌های پیشرفته توسعه API در جاوا هستند، این کتاب را مفید خواهند یافت.

Learn RESTful API design with Java, covering everything from fundamental design principles to advanced techniques for authentication, versioning, error handling, security, testing, performance, and more

Key Features

• Discover essential architectural principles for building robust and adaptable REST APIs
• Gain practical insights into tuning performance and securing endpoints through real-world case studies
• Apply API design concepts to build fully functional services using popular frameworks like Spring Boot

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.
