Spring Boot mock/stub multipe endpoints for component test

I want to create a component test, for a rest endpoint that contact multiple other rest endpoints. The addresses for the endpoints are defined in application.properties. Using WebClient to contact the different endpoints.

req --> service --> remoteService A
                --> remoteService B
                --> remoteService C

How do I stub remoteService A,B and C in a Spring Boot test? I would like to stub the url to the remote services directly instead of overriding the beans for them.
