一.在pom中添加插件

1. 修改swagger地址

<!-- 此插件生成markdown、ASCIIDOC、wiki格式-->
            <!--  執行命令 mvn swagger2markup:convertSwagger2markup-->
            <plugin>
                <groupId>io.github.swagger2markup</groupId>

                    <!-- 生成為單個文檔，輸出路徑-->
                    <outputFile>src/docs/api</outputFile>
                    <!-- 生成為多個文檔，輸出路徑 -->

                        <!-- markdown格式文檔 -->

二.
1、執行mvn swagger2markup:convertSwagger2markup , 可以在idea maven插件中執行
2、生成 html 、pdf，執行1后，執行mvn generate-resources
3、pdf中文顯示存在問題
