Spring-cloud-gateway: Routing is not working - Spring cloud gateway + Eureka Server

[poppinlr]

@SpringBootApplication
@EnableEurekaClient
@Configuration
public class GatewayApplication {

    @Bean
    public RouteLocator customRouteLocator(RouteLocatorBuilder builder) {
        return builder.routes()
                .route("um_route", r -> r
                        .path("/um/**")
                        .uri("lb://user-management")
                )
                .build();
    }
}

discovery.locator is enabled as:

spring.application.name=gateway
server.port=10002

spring.cloud.gateway.discovery.locator.enabled=true
spring.cloud.gateway.discovery.locator.lower-case-service-id=true

application is registed:

but when I http://localhost:10002/um/hello I got 404 as response

ps:
it seems spring cloud gateway have a default config for the routing as /application-name/
so I got response by url http://localhost:10002/user-management/hello
But still don't know how to customize the routing url

You might try adding setPath("/hello") in routing

Can you provide a complete, minimal, verifiable sample that reproduces the problem? It should be available as a GitHub (or similar) project or attached to this issue as a zip file.

I am facing a similar problem, the loadbalancer is not able to retrieve the server list.

Error message:

Service Registry:

Code:

• Eureka Server
• Spring Cloud Gateway
• Rest service

_PS: Works fine when the actual endpoint is provided instead of the service id._

sorry feedback late:
here is my demo projects reproduce the problem:
https://github.com/poppinlr/client.git
https://github.com/poppinlr/gateway.git
https://github.com/poppinlr/serviceManagement.git

I can get response from http://localhost:8082/client/hello
as I said use the default service id
but the java config doesn't work as below
response is 404 as http://localhost:8082/clientc/hello

    @Bean
    public RouteLocator customRouteLocator(RouteLocatorBuilder builder) {
        return builder.routes()
                .route("um_route", r -> r
                        .path("/clinetc/**")
                        .uri("lb://clinet/")
                )
                .build();
    }

your route has spelling errors clinet vs client and clinetc vs clientc.

    @Bean
    public RouteLocator customRouteLocator(RouteLocatorBuilder builder) {
        return builder.routes()
                .route("um_route", r -> r
                        .path("/clientc/**")
                        .filters(f -> f.stripPrefix(1))
                        .uri("lb://client/")
                )
                .build();
    }

.filters(f -> f.stripPrefix(1))

Sorry for spelling mistake,
I think .filters(f -> f.stripPrefix(1)) help to solve the problem, thanks!
