WebClient GET Pattern

easy⏱ 15 minkotlinreactorchallengewebclient

Write the Kotlin code that demonstrates a WebClient GET request pattern. Create a mock function that simulates fetching a user by ID. Return a Mono with "User: John (id=1)". Print the result.

This exercises the pattern without needing actual HTTP.

Why this works

In real Spring WebFlux, WebClient.get().uri(...).retrieve().bodyToMono() returns a Mono. Here we simulate the pattern with a direct Mono.just(), which represents the async result of an HTTP call.

Expected output

User: John (id=1)
