Spring Framework 5 adds a new reactive `WebClient` in addition to the existing `RestTemplate`.
Each supported HTTP client (e.g. Reactor Netty) is adapted to a set of shared,
A `WebClient` instance use a `ClientHttpConnector` implementation to drive the underlying
supported HTTP client (e.g. Reactor Netty). This client is adapted to a set of shared,
reactive `ClientHttpRequest` and `ClientHttpResponse` abstractions that expose the request
and response body as `Flux<DataBuffer>` with full backpressure support on the read and
the write side. The `Encoder` and `Decoder` abstractions from `spring-core` are also used on
the write side. The `HttpMessageReader` and `HttpMessageWriter` abstractions are also used on
the client side for the serialization of a `Flux` of bytes to and from typed objects.

The above assumes static method imports from `ClientWebRequestBuilders` and `ResponseExtractors`
that enable a fluent syntax. The same can also be done with RxJava using static imports from
`RxJava1ClientWebRequestBuilder` and `RxJava1ResponseExtractors` instead:
