Spring WebFlux supports the following features and archetypes:

The event loop concurrency model

Both annotated controllers and functional endpoints

Reactive clients

Netty and Servlet 3.1 container-based web servers, such as Tomcat, Undertow, and Jetty

@SpringBootApplication
public class DemoClientApplication {

   public static void main(String[] args) {
      SpringApplication.run(DemoClientApplication.class, args);
      WebClient webClient = WebClient.builder().baseUrl("http://localhost:8080/").build();
      webClient.get().uri("v1/books")
            .retrieve()
            .bodyToFlux(Book.class)
            .log()
            .subscribe(new Subscriber() {
               Subscription s;
               @Override
               public void onSubscribe(Subscription s) {
                  s.request(1);
                  this.s = s;
               }

               @Override
               public void onNext(Object o) {

                  Book b = (Book) o;
                  System.out.println(b.getName()+" from flux");

                  s.request(1);


               }

               @Override
               public void onError(Throwable t) {

               }

               @Override
               public void onComplete() {
                  System.out.println("done");

               }
            });
      webClient.get().uri("v1/books/1")
            .retrieve()
            .bodyToMono(Book.class)
            .log()
            .subscribe(new Subscriber() {
               @Override
               public void onSubscribe(Subscription s) {
                  s.request(1);
               }

               @Override

                  Book b = (Book)o;
                  System.out.println(b.getName());

               }

               @Override
