### Functional Servlet based Routes

```java

@Configuration

public class FunctionalRouter {

  @Bean

  public RouterFunction routes() {

    return RouterFunctions.route()

                          .POST("/fn", request -> ServerResponse.ok().body("Functional hello!"))

                          .GET("/**", request -> ServerResponse.ok().body("_self: " + request.path()))

                          .filter((request, next) -> {

                            var response = next.handle(request);

                            var headers = HttpHeaders.writableHttpHeaders(response.headers());

                            headers.add("X-FUNCTIONAL", "It's fucking awesome!");

                            return response;

                          })

                          .build();

  }

}
