this is not needed when matching classes based on just name

usually when we use reflection we try to do the reflective lookup only once and reuse the Field/Method. Isn't the gatewayRouterFunction here always GatewayDelegatingRouterFunction? If it is you could look up the field in the static initializer of the class. An other option would be to instrument that class and copy route value into a virtual field that you could read here.

any reason you didn't wish to just use the toString() of the uri?

any reason you didn't add @Test to the super class method?

The spring-cloud-starter-gateway artifact split into two:
When I tried to update the muzzle config to include both new artifacts, I hit some muzzle errors, so I split out webmvc into its own module. I also noticed that we didn't have test coverage for webmvc, so I added some, and realized that it wasn't working so I added some new instrumentation. If we would prefer that I undo all of that and handle it in a separate PR, just let me know.
