HTTP GET Request Example With Spring WebClient

Comment

Once our WebClient is configured for a specific baseUrl, we can start performing HTTP requests.

As the internal WebClient architecture is designed for reactive and non-blocking applications, we either have to call .block() or rewrite our codebase to accept Mono and Flux as method return types.

A simple sync HTTP GET request with our previously configured WebClient looks like the following:

@Service
public class SimpleApiClient {

  private final WebClient defaultWebClient;
  
  // inject the configured WebClient @Bean from the configuration above
  public SimpleApiClient(WebClient defaultWebClient) {
    this.defaultWebClient = defaultWebClient;
  }

  public JsonNode getTodoFromAPI() {
    return this.defaultWebClient
     .get()
     .uri("/todos/1")
     .retrieve()
     .bodyToMono(JsonNode.class)
     .block();
  }
}
