Make route.uri aware of uri variables

Hello guys,
Im trying to use less code for RouteBuilder, but cant see any options for my problem.
So here is the code:
@Bean
public RouteLocator customRouteLocator(RouteLocatorBuilder builder) {
return builder.routes()
.route(
p -> p.path("/api/register/**")
.filters(f ->
f.rewritePath(
"/api/register/(?.*)",
"/${segment}")
)
.uri("lb://erp-register-service")
).build();

The question is: Can I somehow take name of the microservice from the path and
use it in the url(with regex or something , like the rewritePath)??
My idea :
return builder.routes()
.route(
p -> p.path("/api/ ?nameOfMicroservice/**")
.filters(f ->
f.rewritePath(
"/api/register/(?.*)",
"/${segment}")
)
.uri("lb://erp- ?nameOfMicroservice -service")
).build();
Check "?nameOfMicroservice" in path , to go down somehow in the uri, so i can redirect to any microservice
with just 1 RouteBuilder :))

Thanks.

Start by tracing the RouteLocatorBuilder and RouteBuilder APIs used in the example, especially path matching, rewritePath, and uri handling. Define how a microservice name captured from the route path should reach the load-balanced URI, then verify the behavior with the gateway's existing route tests if available.
