Designing Hexagonal Architecture with Java - Second Edition: Build maintainable and long-lasting applications with Java and Quarkus

Learn to build robust, resilient, and highly maintainable cloud-native Java applications with hexagonal architecture and Quarkus

Key Features:

• Use hexagonal architecture to increase maintainability and reduce technical debt
• Learn how to build systems that are easy to change and understand
• Leverage Quarkus to create modern cloud-native applications
• Purchase of the print or Kindle book includes a free PDF eBook

Book Description:

We live in a fast-evolving world with new technologies emerging every day, where enterprises are constantly changing in an unending quest to be more profitable. So, the question arises - how to develop software capable of handling a high level of unpredictability. With this question in mind, this book explores how the hexagonal architecture can help build robust, change-tolerable, maintainable, and cloud-native applications that can meet the needs of enterprises seeking to increase their profits while dealing with uncertainties. This book starts by uncovering the secrets of the hexagonal architecture's building blocks, such as entities, use cases, ports, and adapters. You'll learn how to assemble business code in the domain hexagon, create features with ports and use cases in the application hexagon, and make your software compatible with different technologies by employing adapters in the framework hexagon. In this new edition, you'll learn about the differences between a hexagonal and layered architecture and how to apply SOLID principles while developing a hexagonal system based on a real-world scenario. Finally, you'll get to grips with using Quarkus to turn your hexagonal application into a cloud-native system.

By the end of this book, you'll be able to develop robust, flexible, and maintainable systems that will stand the test of time.

What You Will Learn:

• Apply SOLID principles to the hexagonal architecture
• Assemble business rules algorithms using the specified design pattern
• Combine domain-driven design techniques with hexagonal principles to create powerful domain models
• Employ adapters to enable system compatibility with various protocols such as REST, gRPC, and WebSocket
• Create a module and package structure based on hexagonal principles
• Use Java modules to enforce dependency inversion and ensure software component isolation
• Implement Quarkus DI to manage the life cycle of input and output ports

Who this book is for:

This book is for software architects and Java developers looking to improve code maintainability and enhance productivity with an architecture that allows changes in technology without compromising business logic. Intermediate knowledge of the Java programming language and familiarity with Jakarta EE will help you to get the most out of this book.

書籍描述：
我們生活在一個快速發展的世界中，每天都有新技術出現，企業不斷變化以追求更高的利潤。因此，如何開發能夠應對高度不確定性的軟體成為一個問題。本書探討了六邊形架構如何幫助建立堅固、可變動、易於維護和雲原生的應用程式，以滿足企業在處理不確定性時提高利潤的需求。本書首先揭示了六邊形架構的構建模塊的秘密，例如實體、用例、端口和適配器。您將學習如何在領域六邊形中組合業務代碼，在應用程式六邊形中創建具有端口和用例的功能，並通過在框架六邊形中使用適配器使您的軟體與不同技術兼容。在這個新版本中，您將了解六邊形和分層架構之間的差異，以及如何根據現實情境開發六邊形系統時應用 SOLID 原則。最後，您將學習如何使用 Quarkus 將您的六邊形應用程式轉變為雲原生系統。

通過閱讀本書，您將能夠開發堅固、靈活且易於維護的系統，以應對時間的考驗。

您將學到什麼：
- 將 SOLID 原則應用於六邊形架構
- 使用指定的設計模式組合業務規則算法
- 將領域驅動設計技術與六邊形原則結合，創建強大的領域模型
- 使用適配器實現系統與 REST、gRPC 和 WebSocket 等各種協議的兼容性
- 基於六邊形原則創建模組和封裝結構
- 使用 Java 模組實現依賴反轉，確保軟體組件的隔離性
- 實現 Quarkus DI 以管理輸入和輸出端口的生命週期

本書適合軟體架構師和 Java 開發人員，他們希望通過一種允許在不影響業務邏輯的情況下改變技術的架構來提高代碼的可維護性和生產力。具備中級的 Java 編程語言知識和熟悉 Jakarta EE 將有助於您充分利用本書的內容。
