《Spring Boot in Action》是一本專為熟悉 Spring Framework 的開發者所寫的實戰指南，聚焦於如何運用 Spring Boot 大幅簡化 Java 應用程式的開發流程。Spring Boot 以「約定優於設定」為核心理念，讓開發者跳過繁瑣的組態工作，快速啟動專案，將心力集中在應用程式的行為與商業邏輯上。作者 Craig Walls 以多年 Spring 開發與教學經驗，透過清楚且實用的範例，說明如何有效運用 Spring Boot 的自動組態機制，同時在需要時進行客製化調整。書中涵蓋測試、部署、Actuator 監控、命令列工具（CLI）、以及與 Groovy、Grails 的整合應用，完整呈現 Spring Boot 在實務開發中的優勢。本書內容務實、節奏明快，適合希望提升開發效率、減少設定負擔的 Java 與 Spring 開發者閱讀，是理解與上手 Spring Boot 的重要入門與進階參考。Although Spring Framework simplifies enterprise Java development, it can require a lot from developers in terms of framework configuration. Spring Boot radically streamlines the process of creating Spring applications by employing automatic configuration, along with a programming model built around established conventions for build-time and runtime dependencies. It also provides a component that gives insight into the internals of a running application and a handy CLI that can be used to write command-line scripts in Groovy. Developers who have used Spring Boot say that th
