URL base routing

In project gw

@Bean
public RouteLocator MyRoute(RouteLocatorBuilder builder) {
    return builder//
            .routes()//
            .route("svc1", r -> r.path("/svc1/**")
                    //
                    .filters(f -> f.stripPrefix(1))
                    //
                    .uri("lb://svc1"))//
            .route("svc2", r -> r.path("/svc2/**")
                    //
                    .filters(f -> f.filter(authFilter).stripPrefix(1))
                    //
                    .uri("lb://svc2"))//
            .build();
}
