<content type="html"><![CDATA[<h5 id="作者博客"><a href="#作者博客" class="headerlink" title="@作者博客"></a><a href="http://www.1314sl.com">@作者博客</a></h5><p>由于Spring Boot能够快速开发、便捷部署等特性，相信有很大一部分Spring Boot的用户会用来构建RESTful API。而我们构建RESTful API的目的通常都是由于多终端的原因，这些终端会共用很多底层业务逻辑，因此我们会抽象出这样一层来同时服务于多个移动端或者Web前端。</p><p>这样一来，我们的RESTful API就有可能要面对多个开发人员或多个开发团队：IOS开发、Android开发或是Web开发等。为了减少与其他团队平时开发期间的频繁沟通成本，传统做法我们会创建一份RESTful API文档来记录所有接口细节，然而这样的做法有以下几个问题：</p><a id="more"></a><ul><li>由于接口众多，并且细节复杂（需要考虑不同的HTTP请求类型、HTTP头部信息、HTTP请求内容等），高质量地创建这份文档本身就是件非常吃力的事，下游的抱怨声不绝于耳。</li><li>随着时间推移，不断修改接口实现的时候都必须同步修改接口文档，而文档与代码又处于两个不同的媒介，除非有严格的管理机制，不然很容易导致不一致现象。</li></ul><p>为了解决上面这样的问题，本文将介绍RESTful API的重磅好伙伴Swagger2，它可以轻松的整合到Spring Boot中，并与Spring MVC程序配合组织出强大RESTful API文档。它既可以减少我们创建文档的工作量，同时说明内容又整合入实现代码中，让维护文档和修改代码整合为一体，可以让我们在修改代码逻辑的同时方便的修改文档说明。另外Swagger2也提供了强大的页面测试功能来调试每个RESTful API</p><h3
