swagger-export是一个提供swagger文档导出功能的服务，不依赖于具体的API接口服务实现，你可以很方便地导出html和pdf两种格式的静态文档。源码来自swagger导出静态API文档工具，做了一些修改，以符合实际的项目需要。

一.在src下配置asciidoc

 二.pom.xml

也就是maven插件

导出步骤

1. 启动待导出的API接口服务；

2. 修改pom文件中properties配置的swaggerInputPath值为目标服务的IP端口信息；

3. 在当前目录执行mvn clean compile命令；

4. 生成的文档有html和pdf两种格式，目录分别为

target\docs\asciidoc\html\index.htmltarget\docs\asciidoc\pdf\index.pdf

导出的pdf格式文件，中文存在显示问题。可用Word2016打开，然后另存为word格式文件。

注意：

导出时，如果有数据权限，得放出  /v2/api-docs 接口。
