    connect(HttpMethod method, URI uri, Function<? super ClientHttpRequest,reactor.core.publisher.Mono<Void>> requestCallback)
    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.
    int
    getPhase()
    Return the phase that this lifecycle object is supposed to run in.
    boolean
    isAutoStartup()
    Returns true if this Lifecycle component should get started automatically by the container at the time that the containing ApplicationContext gets refreshed.
    boolean
    isRunning()
    Check whether this component is currently running.
    void
    start()
    Start this component.
    void
    stop()
    Stop this component, typically in a synchronous fashion, such that the component is fully stopped upon return of this method.
    final void
    stop(Runnable callback)

    • ReactorClientHttpConnector

      public ReactorClientHttpConnector()
      Default constructor. Initializes HttpClient via: 
       HttpClient.create().compress()

    • ReactorClientHttpConnector

      public ReactorClientHttpConnector(ReactorResourceFactory resourceFactory, Function<reactor.netty.http.client.HttpClient,reactor.netty.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 ReactorResourceFactory bean with globalResources=true in order to ensure the Reactor Netty global resources are shut down when the Spring ApplicationContext is stopped or closed and restarted properly when the Spring ApplicationContext is (with JVM Checkpoint Restore for example).

      Parameters:
      resourceFactory - the resource factory to obtain the resources from
      mapper - a mapper for further initialization of the created client
