通过swagger json一键解析为html页面、导出word和excel的解析算法分享
写在前面：
完全通过Spring Boot工程 Java代码，将swagger json 一键解析为html页面、导出word和execel的解析算法，不需要任何网上那些类似于“SwaggerMarkup2”等插件来实现。
由于业务需要，准备开发一个openapi开放平台，类似于阿里巴巴的CSB云服务总线项目，用于企业内外服务能力的打通和统一开放管理，提供独特的跨环境服务级联机制和常见协议适配支持，实现了对api接口的对外发布和订阅审核，让企业内外都能够更方便的使用到api接口。
其中需要实现一个核心功能，服务的导入功能，通过swagger json将我们其他项目中已经写好的接口一键导入到这个api开放平台并生成api接口详情页，那么这就需要实现一个swagger json解析的操作。
下面马上进入正题，本文主要也是分享一下，自己解析swagger json为html、word等功能的代码、思路以及界面。
页面效果展示：
将下图这样的swagger json解析出一个个api接口详情页。
解析前：
解析后：
通过json解析完可以显示所有的接口信息，如图：
这是单个接口的api详情信息，如下图：
点击按钮导出api详情页为word的效果展示，如图：
导出word：
Swagger Json格式详解：
代码部分：
我这边实现两种思路，一是直接解析swagger json然后直接存入实体类生成为html，还要一种是建立好实体类以及数据库表后，将swagger json解析入库入表做持久化，再通过表中数据渲染到页面上。
下面我是介绍的swagger json入库入表再渲染为html的方案。
步骤大概是：首先定义好建好表，写好实体类后，再开始实现swagger json解析的算法。
实体类定义：

使用思路：
首先通过swagger json解析为实体类并存入数据库中（对应上面的swagger解析代码），在通过调用javabean转html的接口来实现将存入的数据转为html页面（对应上面的javabean转为html渲染页面代码）。
结尾：
总结：
其实也可以直接通过swagger json解析然后存入实体类直接渲染给页面。就是不入库直接将swaggerjson生成出html，这种方案我也实现了，但是在这篇文章中不做过多介绍，如果有需要以后我也会写篇文章做一下记录。
其实都是一样的思路啦，写代码讲究的是思路。
