sends them to remote APIs and returns the response to the API/UI clients. In such cases, after making the request, we must return aMonoorFluxto the API/UI client to keep the whole flow truly reactive.
WebClientis part of theSpring WebFluxlibrary. So,we can also write client code using a functional, fluent API with reactive types (MonoandFlux) as a declarative composition. 3. Comparison Example To demonstrate the differences between these two approaches, we’d need to run performance tests with...
Here, we retrieve the user without specifying the status code. 3.4. Altering Response Body Furthermore, let’s see an example that alters the response body: @GetMapping("/user/exchange-alter/{id}")Mono<User>retrieveOneUserWithExchange(@PathVariableintid){returnclient.get() .uri("/{id}", i...
