SpringCloud Gateway与swagger集成解决方案

spring cloud gateway 底层采用的是webflux，swagger2暂时不支持webflux，网上的解决方案虽然有一些，比如这篇文章 还有《重新定义spring cloud 实战》这本书也有解决方案，书源码链接，
我们项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：

            org.springframework.boot            spring-boot-starter-integration                            org.springframework.integration            spring-integration-webflux                            io.springfox            springfox-swagger2            3.0.0-SNAPSHOT                            io.springfox            springfox-spring-webflux            3.0.0-SNAPSHOT                            io.springfox            springfox-spring-integration-webflux            3.0.0-SNAPSHOT                            io.springfox            springfox-swagger-ui            3.0.0-SNAPSHOT                                                ch.qos.logback                    logback-classic                                                    ch.qos.logback                    logback-core                                                    还要引入资源库                                    jcenter-snapshots            jcenter            http://oss.jfrog.org/simple/oss-snapshot-local/io/springfox/                           false                                       true                        

因为公司的构建系统只代理这几个仓库：
http://repo1.maven.org/maven2/
http://jcenter.bintray.com/
http://repo.grails.org/grails/core/

所以虽然本地可以调试，但是服务器上构建失败，最后结局方案是，把swagger3的jar包引入本地lib文件，然后在pom中引入，解决问题。这是一个细心的活~

希望swagger官方尽早提供swagger3的release版本。
