话不多说，直接上硬货：

这是gateway 官网的配置截图

这个配置简单，但是我们需要同时支持http 和https

目前这个问题官方还没有正式解决

**民间人士，想到的办法是 在启动一个Netty 监听另外一个端口 如：8080，这个端口是不带 s 的也就是   http**

**当访问8080时 跳转到配置https 的如8443端口 **

经过一番查找

### 具体实现： ###

package cn.com.test.gateway.config;
     
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.boot.web.embedded.netty.NettyReactiveWebServerFactory;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.http.HttpStatus;
    import reactor.core.publisher.Mono;
     
    import javax.annotation.PostConstruct;
    import java.net.URI;
    import java.net.URISyntaxException;
    
    @Configuration
    public class HttpToHttpsRedirectConfig {
    
        @Value("${server.http.port}")
        private int httpPort;
        @Value("${server.port}")
        private int serverPort;
    
        @PostConstruct
        public void startRedirectServer() {
            NettyReactiveWebServerFactory httpNettyReactiveWebServerFactory = new NettyReactiveWebServerFactory(httpPort);
            httpNettyReactiveWebServerFactory.getWebServer((request, response) -> {
                URI uri = request.getURI();
                URI httpsUri;
                try {
                    httpsUri = new URI("https", uri.getUserInfo(), uri.getHost(), serverPort, uri.getPath(), uri.getQuery(), uri.getFragment());
                } catch (URISyntaxException e) {
                    return Mono.error(e);
                }
                response.setStatusCode(HttpStatus.MOVED_PERMANENTLY);
                response.getHeaders().setLocation(httpsUri);
                return response.setComplete();
            }).start();
        }
    
    
    }

yml 配置文件配置：

分为俩个端口号，server.port 是配置https 的端口， http.port 是监听的端口

server:
      http:
        port: 4321
      port: 1234
      ssl:
        enabled: true
        key-alias: scg
        key-store: classpath:ssl/test.pfx
        key-store-password: 6540CNd4Whw
        keyStoreType: PKCS12

目录结构：

启动后访问，不带s 的4321端口会转发到1234端口。

记得双击摸摸哒！

一键三连摸摸哒！
