pom引入依赖

       
            org.springframework.boot
            spring-boot-starter-webflux
        

代码

package org.qx.web.router;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.function.RequestPredicates;
import org.springframework.web.servlet.function.RouterFunction;
import org.springframework.web.servlet.function.RouterFunctions;
import org.springframework.web.servlet.function.ServerResponse;

import static org.springframework.web.servlet.function.EntityResponse.fromObject;
import static org.springframework.web.servlet.function.ServerResponse.ok;

@Configuration
public class MyRouters {
    @Bean
    public RouterFunction helloRoutesV1() {
        return RouterFunctions.route(RequestPredicates.path("/v1/hello-world"),
                request -> ok().body(fromObject("Hello World v1!")));
    }

    @Bean
    public RouterFunction helloRoutesV2() {
        return RouterFunctions.route(RequestPredicates.path("/v2/hello-world"),
                request -> ok().body(fromObject("Hello World v2!!!")));
    }

}

异常情况

Unable to load io.netty.resolver.dns.macos.MacOSDnsServerAddressStreamProvider

解决：

引入pom依赖

    io.netty
    netty-all

解析：

其实用的是routerFunctionMapping 去进行路由解析的
