In practice, it’s similar to Java’s own CompletableFuture: it represents a single future value. MonoĪ Mono is a specific but very common type of Flux: a Flux that will asynchronously emit either 0 or 1 results before it completes. A Flux is a stream that we can transform (giving us a new stream of transformed events), buffer into a List, reduce down to a single value, concatenate and merge with other Fluxes, or block on to wait for a value. In reactive programming, this is our bread-and-butter. It’s a sequence that will asynchronously emit any number of items (0 or more) in the future, before completing (either successfully or with an error). FluxĪ Flux represents a stream of elements. This is an asynchronous operation, which doesn’t block or wait for the request itself, which means that on the following line the request is still pending, and so we can’t yet access any of the response details.īefore we can get a value out of this asynchronous operation, you need to understand the Flux and Mono types from Reactor. retrieve() to get a ResponseSpec for a request. Once we’ve made a request, we usually want to read the contents of the response.

How do we do that? How to Handle an HTTP Response with WebClient This is everything required to send a request, but it’s important to note that no request has actually been sent at this point! As a reactive API, the request is not actually sent until something attempts to read or wait for the response.

If you’re using Spring Boot you can use spring-boot-starter-webflux, or alternatively you can install spring-webflux and reactor-netty directly. To get started, you’ll first need to add some dependencies to your project, if you don’t have them already. Let’s start simple, with a plain GET request to read some content from a server or API. In this article we’ll look first at how you can start sending simple GET and POST requests to an API with WebClient right now, and then discuss how to take WebClient further for advanced use in substantial production applications. Using WebClient you can make synchronous or asynchronous HTTP requests with a functional fluent API that can integrate directly into your existing Spring configuration and the WebFlux reactive framework. Using WebFlux, you can build asynchronous web applications, using reactive streams and functional APIs to better support concurrency and scaling.Īs part of this, Spring 5 introduced the new WebClient API, replacing the existing RestTemplate client. This is designed to co-exist alongside the existing Spring Web MVC APIs, but to add support for non-blocking designs. In Spring 5, Spring gained a reactive web framework: Spring WebFlux.
