生成Swagger2静态文档

一、代码生成静态文档<!-- swagger生成接口API -->

        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.6.0</version>
        </dependency>
        <!-- 接口API生成html文档 -->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.6.0</version>
        </dependency>
        <dependency>
            <groupId>io.github.swagger2markup</groupId>
            <artifactId>swagger2markup</artifactId>
            <version>1.3.1</version>　　　　　　　
        </dependency>
        <dependency>
            <groupId>io.swagger</groupId>
            <artifactId>swagger-core</artifactId>
            <version>1.5.16</version>
        </dependency>
        <dependency>
            <groupId>io.swagger</groupId>
            <artifactId>swagger-models</artifactId>
            <version>1.5.16</version>
        </dependency>
        <dependency>
            <groupId>org.pegdown</groupId>
            <artifactId>pegdown</artifactId>
            <version>1.4.2</version>
        </dependency>

如果开发项目直接添加依赖，为不影响正常项目启动，可以在给swagger2markup添加<scope>test</scope>　　　　　

<dependency>
        <groupId>io.github.swagger2markup</groupId>
        <artifactId>swagger2markup</artifactId>
        <version>1.3.1</version>
　　　　 <scope>test</scope>
</dependency>

jar包容易出问题：
正常后面两个jar是不需要的,因为jar包容易报错
java.lang.NoSuchMethodError: io.swagger.models.Response.responseSchema(Lio/swagger/models/Model;)Lio/swagger/models/Response;
java.lang.NoSuchFieldError: MULTIPLE_OF
因为 springfox-swagger2 --2.60这个版本里面对应的swagger-core是1.5.12 ，swagger-models是1.5.10的。想要通过swagger2markup生成静态文档需要通过core和model转换成对应的实体格式。然而core和model好像11前都没有向后兼容，所以需要core和model都需要在1.5.11之上。引入的 core和model就是为了替换springfox-swagger2里面的包

二、通过maven插件生成
1、生成ASCIIDOC等，效果等同上面代码（可以不加）

           <plugin>
                <groupId>io.github.swagger2markup</groupId>
                <artifactId>swagger2markup-maven-plugin</artifactId>
                <version>1.3.4</version>
                <configuration>
                    <swaggerInput>http://localhost:9090/v2/api-docs</swaggerInput><!---swagger-api-json路径-->
                    <outputDir>./docs/asciidoc/generated</outputDir><!---生成路径-->
                    <config>
                        <swagger2markup.markupLanguage>ASCIIDOC</swagger2markup.markupLanguage><!--生成格式-->
                    </config>
                </configuration>
            </plugin>

mvn执行swagger2markup:convertSwagger2markup
若遇到问题java.lang.NoClassDefFoundError: org/pegdown/PegDownProcessor修改swagger2markup-maven-plugin-1.3.4.pom增加

        <dependency>
            <groupId>org.pegdown</groupId>
            <artifactId>pegdown</artifactId>
            <version>1.4.2</version>
        </dependency>        

2、生成html(前提是已经存在ASCIIDOC)

　　　　　　　　<plugin>
                <groupId>org.asciidoctor</groupId>
                <artifactId>asciidoctor-maven-plugin</artifactId>
                <version>1.5.6</version>
                <configuration>
                    <!--asciidoc文件目录，请确认文件已经存在-->
                    <sourceDirectory>./docs/asciidoc/generated</sourceDirectory>
                    <!---生成html的路径-->
                    <outputDirectory>./docs/asciidoc/html</outputDirectory>
                    <backend>html</backend>
                    <sourceHighlighter>coderay</sourceHighlighter>
                    <attributes>
                        <!--导航栏在左-->
                        <toc>left</toc>
                        <!--显示层级数-->
                        <toclevels>3</toclevels>
                        <!--自动打数字序号-->
                        <sectnums>true</sectnums>
                    </attributes>
                </configuration>
            </plugin>
