Swagger接口如何生成Html离线文档

A very simple tool that converts Swagger Api Document to Html File.

小记Swagger接口生成Html离线文档

由来

很多人用swagger2markup以及asciidoctor-maven-plugin插件来生成html格式的文档。

由于swagger2markup依赖的asm库版本较低, 且依赖较多, 容易与项目中依赖的核心库冲突。

所以, 干脆把Swagger接口文档转为Html文档独立出来, 做成一个小工具, 这样就清爽干净多了！

使用

        # 下载源码
git clone https://github.com/iflyendless/Swagger2Html.git

# 编译打包
mvn clean package

# 使用target目录下的jar包, 参数是swagger接口数据
java -jar Swagger2Html-1.0-SNAPSHOT-jar-with-dependencies.jar http://localhost:8080/v2/api-docs

    

当前目录下便会新增api.html文件，用浏览器打开效果如下图：

看起来是不是有模有样的! 建议正在使用swagger的朋友可以感受一下生成的离线Html。

实现

完整源码见：https://github.com/iflyendless/Swagger2Html

引入依赖：

        <dependency>
    <groupId>io.github.swagger2markup</groupId>
    <artifactId>swagger2markup</artifactId>
    <version>1.3.3</version>
</dependency>

<dependency>
    <groupId>org.asciidoctor</groupId>
    <artifactId>asciidoctorj</artifactId>
    <version>2.4.3</version>
</dependency>

    

代码实现：

        import io.github.swagger2markup.GroupBy;
import io.github.swagger2markup.Language;
import io.github.swagger2markup.Swagger2MarkupConfig;
import io.github.swagger2markup.Swagger2MarkupConverter;
