Spring 5 - Functional, reactive web example

This repository contains the sample code for Spring WebFlux’s functional web API and consists of the following building blocks:

A sample for Spring WebFlux

1. An Event domain type and a corresponding repository exposing a tailable query method.

2. An ApplicationRunner that creates a capped collection for events and inserts a new one every two seconds.

3. A Spring WebFlux controller to produce both a Server-Sent Events and JSON stream.

A sample for Spring WebFlux.fn

1. A User domain type and a reactive repository mapped using Spring Data MongoDB.

2. A FunctionalWebController to contain handler functions.

3. An @Bean-Definition for a RouterFunction that uses the functional API to configure the mappings of requests to the FunctionalWebController.

How to run the sample

$ git clone https://github.com/olivergierke/spring-five-functional-reactive
$ cd spring-five-functional-reactive
$ ./mvnw spring-boot:run

# To see the events inserted on the server streaming to the client
$ curl -H "Accept: text/event-stream" http://localhost:8080/events

# To trigger the functional controller
$ curl http://localhost:8080/users
