How to append prefix in gateway server in new spring boot 2.6.4?

Question

Previously, I was using Spring boot 2.2.6.RELEASE with dependency spring-cloud-starter-netflix-zuul and spring cloud version Hoxton.SR3. In this for gateway server, I was using following configuration in application.yml:

zuul:
  host:
    prefix: /api
    routes:
      userapp:
        path: /userapp/**
        sensitiveHeaders: null
        serviceId: userapp

Suppose, gateway server port is 8765 and userapp port is 8080. Now, if userapp has an api http://localhost:8080/get/id/{userid}, then from gateway server, same api would be: http://localhost:8765/api/userapp/get/id/{userid}. Here, I am able to append prefix /api/userapp from the Gateway server.

Now, in new Spring boot version 2.6.4 with dependency spring-cloud-starter-gateway and spring cloud version 2021.0.1, I am using following configuration in application.yml of the Gateway server:

spring:
  cloud:
    gateway:
      discovery:
        locator:
          enabled: true
          route-id-prefix: /api/userapp
      routes:
        - id: userapp
          uri: lb://userapp/
          predicates:
          - Path=/**

Now, here I am not able to append prefix like before. I have to use http://localhost:8765/get/id/{userid} to get data from gateway server. One solution is I have to append all apis in userapp with /api/userapp, then I can use http://localhost:8765/api/userapp/get/id/{userid}.

So, how can I append different prefix for different microservices in this new Spring boot instead of appending prefix in all apis individually in all microservices.
