测试类

@Test
	public void generateMarkdownDocsToFile() throws Exception {
		//    输出Markdown到单文件
		Swagger2MarkupConfig config = new Swagger2MarkupConfigBuilder()
				.withMarkupLanguage(MarkupLanguage.MARKDOWN)
				.withOutputLanguage(Language.ZH)
				.withPathsGroupedBy(GroupBy.TAGS)
				.withGeneratedExamples()
				.withoutInlineSchema()
				.build();

		Swagger2MarkupConverter.from(new URL("http://localhost:8080/myproject/v2/api-docs"))
				.withConfig(config)
				.build()
				.toFile(Paths.get("./docs/markdown/generated/all"));
	}

输入命令:mvn clean test
会在根目录下生成docs文件夹,里面就有生成的文件

虽然是md格式,但是有一个神器网站:http://coolaf.com/tool/md 把md格式的文件复制进去,下载下来即可.
