Constructor Details

ReactorNetty2ClientHttpConnector

public ReactorNetty2ClientHttpConnector()

Default constructor. Initializes HttpClient via:

 HttpClient.create().compress()
 

ReactorNetty2ClientHttpConnector

public ReactorNetty2ClientHttpConnector(ReactorNetty2ResourceFactory factory,
 Function<reactor.netty5.http.client.HttpClient,reactor.netty5.http.client.HttpClient> mapper)

Constructor with externally managed Reactor Netty resources, including LoopResources for event loop threads, and ConnectionProvider for the connection pool.

This constructor should be used only when you don't want the client to participate in the Reactor Netty global resources. By default, the client participates in the Reactor Netty global resources held in HttpResources, which is recommended since fixed, shared resources are favored for event loop concurrency. However, consider declaring a ReactorNetty2ResourceFactory bean with globalResources=true in order to ensure the Reactor Netty global resources are shut down when the Spring ApplicationContext is closed.

Parameters:

factory - the resource factory to obtain the resources from

mapper - a mapper for further initialization of the created client

Since:

5.1

ReactorNetty2ClientHttpConnector

public ReactorNetty2ClientHttpConnector(reactor.netty5.http.client.HttpClient httpClient)

Constructor with a pre-configured HttpClient instance.

Parameters:

httpClient - the client to use

Since:

5.1

Method Details

connect

public reactor.core.publisher.Mono<ClientHttpResponse> connect(HttpMethod method,
 URI uri,
 Function<? super ClientHttpRequest,reactor.core.publisher.Mono<Void>> requestCallback)

Description copied from interface: ClientHttpConnector

Connect to the origin server using the given HttpMethod and URI and apply the given requestCallback when the HTTP request of the underlying API can be initialized and written to.

Specified by:

connect in interface ClientHttpConnector

Parameters:

method - the HTTP request method

uri - the HTTP request URI

requestCallback - a function that prepares and writes to the request, returning a publisher that signals when it's done writing. Implementations can return a Mono<Void> by calling ReactiveHttpOutputMessage.writeWith(org.reactivestreams.Publisher<? extends org.springframework.core.io.buffer.DataBuffer>) or ReactiveHttpOutputMessage.setComplete().

Returns:

publisher for the ClientHttpResponse
