Trying to understand the example code better..

when the URL to go is http://localhost:9080/backendC/success

it fetches response as Hello World from backend A

Unable to know, the code that is routing to backend A Service..

as console says
dev-app-1 | 2023-07-24T09:54:29.567Z INFO 205 --- [or-http-epoll-3] io.github.robwin.Application : 2023-07-24T09:54:29.567386638Z[Etc/UTC]: CircuitBreaker 'backendC' recorded a successful call. Elapsed time: 0 ms

Can you pl. point me to the code making this happen.
