SpringCloud Gateway與swagger集成解決方案

spring cloud gateway 底層采用的是webflux，swagger2暫時不支持webflux，網上的解決方案雖然有一些，比如這篇文章 還有《重新定義spring cloud 實戰》這本書也有解決方案，書源碼鏈接，
我們項目里面采用的是集成了最新的swagger3 snapshot版本，需要引入的pom文件有：

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-integration</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.integration</groupId>
            <artifactId>spring-integration-webflux</artifactId>
        </dependency>

        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>3.0.0-SNAPSHOT</version>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-spring-webflux</artifactId>
            <version>3.0.0-SNAPSHOT</version>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-spring-integration-webflux</artifactId>
            <version>3.0.0-SNAPSHOT</version>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>3.0.0-SNAPSHOT</version>
            <exclusions>
                <exclusion>
                    <groupId>ch.qos.logback</groupId>
                    <artifactId>logback-classic</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>ch.qos.logback</groupId>
                    <artifactId>logback-core</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

                還要引入資源庫
                <repositories>
        <repository>
            <id>jcenter-snapshots</id>
            <name>jcenter</name>
            <url>http://oss.jfrog.org/simple/oss-snapshot-local/io/springfox/</url>
            <releases>
               <enabled>false</enabled>
            </releases>
            <snapshots>
               <enabled>true</enabled>
            </snapshots>
        </repository>
    </repositories>

因為公司的構建系統只代理這幾個倉庫：
http://repo1.maven.org/maven2/
http://jcenter.bintray.com/
http://repo.grails.org/grails/core/

所以雖然本地可以調試，但是服務器上構建失敗，最后結局方案是，把swagger3的jar包引入本地lib文件，然后在pom中引入，解決問題。這是一個細心的活~

springfox提供的快照版本：https://springfox.github.io/springfox/docs/current/#maven
希望swagger官方盡早提供swagger3的release版本。
