Class ReactorClientHttpRequestFactory

java.lang.Object
org.springframework.http.client.ReactorClientHttpRequestFactory
All Implemented Interfaces:
org.springframework.context.Lifecycle, org.springframework.context.Phased, org.springframework.context.SmartLifecycle, ClientHttpRequestFactory
public class ReactorClientHttpRequestFactory extends Object implements ClientHttpRequestFactory, org.springframework.context.SmartLifecycle
Reactor-Netty implementation of ClientHttpRequestFactory.

This class implements SmartLifecycle and can be optionally declared as a Spring-managed bean in order to support JVM Checkpoint Restore.

  • Constructor Details

    • ReactorClientHttpRequestFactory

      public ReactorClientHttpRequestFactory()
      Constructor with default client, created via HttpClient.create(), and with compression and proxyWithSystemProperties enabled.

    • ReactorClientHttpRequestFactory

      public ReactorClientHttpRequestFactory(reactor.netty.http.client.HttpClient client)
      Constructor with a given HttpClient instance.
      Parameters:
      client - the client to use

    • ReactorClientHttpRequestFactory

      public ReactorClientHttpRequestFactory(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 connection pooling.

      Generally, it is recommended to share resources for event loop concurrency. This can be achieved either by participating in the JVM-wide, global resources held in HttpResources, or by using a specific, shared set of resources through a ReactorResourceFactory bean. The latter can ensure that resources are shut down when the Spring ApplicationContext is stopped/closed and restarted again (e.g. JVM checkpoint restore).

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

  • Method Details

    • setExecutor

      public void setExecutor(Executor executor)
      Set the Executor to use for performing blocking I/O operations.

      If no executor is provided, the request will use an elastic scheduler.

      Parameters:
      executor - the executor to use.

    • setConnectTimeout

      public void setConnectTimeout(int connectTimeout)
      Set the connect timeout value on the underlying client. Effectively, a shortcut for httpClient.option(CONNECT_TIMEOUT_MILLIS, timeout).

      By default, set to 30 seconds.

      Parameters:
      connectTimeout - the timeout value in millis; use 0 to never time out.
      See Also:
      • Transport.option(ChannelOption, Object)
      • ChannelOption.CONNECT_TIMEOUT_MILLIS
      • Connection Timeout

    • setConnectTimeout

      public void setConnectTimeout(Duration connectTimeout)
      Variant of setConnectTimeout(int) with a Duration value.

    • setReadTimeout

      public void setReadTimeout(Duration timeout)
      Set the read timeout value on the underlying client. Effectively, a shortcut for HttpClient.responseTimeout(Duration).

      By default, set to 10 seconds.

      Parameters:
      timeout - the read timeout value in millis; must be > 0.

    • setReadTimeout

      public void setReadTimeout(long readTimeout)
      Variant of setReadTimeout(Duration) with a long value.

    • createRequest

      public ClientHttpRequest createRequest(URI uri, HttpMethod httpMethod) throws IOException
      Description copied from interface: ClientHttpRequestFactory
      Create a new ClientHttpRequest for the specified URI and HTTP method.

      The returned request can be written to, and then executed by calling ClientHttpRequest.execute().

      Specified by:
      createRequest in interface ClientHttpRequestFactory
      Parameters:
      uri - the URI to create a request for
      httpMethod - the HTTP method to execute
      Returns:
      the created request
      Throws:
      IOException - in case of I/O errors
