Spring 云网关出现404路由错误

Question

Spring cloud gateway does not forward my request to the next microservice. The result is always 404.

 @SpringBootApplication public class TwoFactorAuthenticationServiceApplication { @Bean public RouteLocator customRouteLocator(RouteLocatorBuilder builder) { return builder.routes().route("path_route", r -> r.path("/two-factor-authentication-service-1.0/get").uri("http://localhost:10270/wallet-management-service-1.0/api/system-wallet/get-wallet-address")).route("host_route", r -> r.host("*.myhost.org").uri("http://httpbin.org")).build(); } public static void main(String[] args) { SpringApplication.run(TwoFactorAuthenticationServiceApplication.class, args); } }

The response is

Answer 1

The problem seemed My application works on spring MVC and Spring cloud gateway is for webflux only.
