Modify the request path using the streaming API of gateway

I saw this writing on the official website

spring:
  cloud:
    gateway:
      routes:
      - id: nameRoot
        uri: https://nameservice
        predicates:
        - Path=/name/**
        filters:
        - StripPrefix=2

When the gateway forwarding request path is /name/blue/red when , Actually to nameservice forwarding nameservice/red request , Streaming is not given on the official website api Of chestnuts

You can use the following code to achieve

    @Bean
    public RouteLocator customRouteLocator(RouteLocatorBuilder builder) {
    


        return builder.routes()
                .route("oauth",
                        f-> f.path("/oauth/**")
                                .filters(gatewayFilterSpec -> gatewayFilterSpec.rewritePath("/oauth",""))
                                .uri("lb://oauth")
                ).build();

    }

But there are still problems , If you change the official website to streaming api To write , how did you know? name There must be blue Like the following

    @Bean
    public RouteLocator customRouteLocator(RouteLocatorBuilder builder) {
    


        return builder.routes()
                .route("nameRoot",
                        f-> f.path("/name/**")
                        // Here's the problem 
                                .filters(gatewayFilterSpec -> gatewayFilterSpec.rewritePath("/name/blue",""))
                                .uri("lb://nameservice")
                ).build();

    }

hope
