　　重构，一言以蔽之，就是在不改变外部行为的前提下，有条不紊地改善代码。多年前，正是本书原版的出版，使重构终于从编程高手们的小圈子走出，成为众多普通程序员日常开发工作中不可或缺的一部分。《重构：改善既有代码的设计（评注版）》也因此成为与《设计模式》齐名的经典著作，被译为中、德、俄、日等众多语言，在世界范围内畅销不衰。

　　Martin Fowler等著的《重构：改善既有代码的设计（评注版）》凝聚了软件开发社区专家多年摸索而获得的宝贵经验，拥有不因时光流逝而磨灭的价值。今天，无论是重构本身，业界对重构的理解，还是开发工具对重构的支持力度，都与本书最初出版时不可同日而语，但书中所蕴涵的意味和精华，依然值得反复咀嚼，而且往往能够常读常新。

　　《重构：改善既有代码的设计（评注版）》力邀国内资深专家执笔，在英文原著基础上增加中文点评与注释，旨在以先行者的学研心得与实践感悟，对读者阅读与学习加以点拨、指明捷径。
　　Martin Fowler世界级软件开发大师，在面向对象分析设计、UML、模式、XP和重构等领域都有卓越贡献，曾任著名软件开发咨询公司ThoughtWorks的首席科学家。他的多部著作《分析模式》、《UML精悴》和《企业应用架构模式》等都已经成为脍炙人口的经典。
