public class TcpOutboundGateway extends AbstractReplyProducingMessageHandler implements TcpSender, TcpListener, ManageableLifecycle
TCP outbound gateway that uses a client connection factory. If the factory is configured for single-use connections, each request is sent on a new connection; if the factory does not use single use connections, each request is blocked until the previous response is received (or times out). Asynchronous requests/responses over the same connection are not supported - use a pair of outbound/inbound adapters for that use case.

Lifecycle methods delegate to the underlying AbstractConnectionFactory.

    • setIntegrationEvaluationContext

      public void setIntegrationEvaluationContext(EvaluationContext evaluationContext)

    • setReplyChannel

      public void setReplyChannel(MessageChannel replyChannel)
      Specify the Spring Integration reply channel. If this property is not set the gateway will check for a 'replyChannel' header on the request.
      Parameters:
      replyChannel - The reply channel.

    • setReplyChannelName

      public void setReplyChannelName(String replyChannel)
      Specify the Spring Integration reply channel name. If this property is not set the gateway will check for a 'replyChannel' header on the request.
      Parameters:
      replyChannel - The reply channel.

    • setUnsolicitedMessageChannelName

      public void setUnsolicitedMessageChannelName(String unsolicitedMessageChannelName)
      Set the channel name for unsolicited incoming messages, or late replies.
      Parameters:
      unsolicitedMessageChannelName - the channel name.
      Since:
      5.4

    • setUnsolicitedMessageChannel

      public void setUnsolicitedMessageChannel(MessageChannel unsolicitedMessageChannel)
      Set the channel for unsolicited incoming messages, or late replies.
      Parameters:
      unsolicitedMessageChannel - the channel.
      Since:
      5.4

    • setCloseStreamAfterSend

      public void setCloseStreamAfterSend(boolean closeStreamAfterSend)
      Set to true to close the connection ouput stream after sending without closing the connection. Use to signal EOF to the server, such as when using a ByteArrayRawSerializer. Requires a single-use connection factory.
      Parameters:
      closeStreamAfterSend - true to close.
      Since:
      5.2

    • setSecondChanceDelay

      public void setSecondChanceDelay(int secondChanceDelay)
      When using NIO and the server closes the socket after sending the reply, an error message representing the close may appear before the reply. Set the delay, in seconds, to wait for an actual reply after an ErrorMessage is received. Default 2 seconds.
      Parameters:
      secondChanceDelay - the delay.

    • getComponentType

      public String getComponentType()
      Description copied from class: IntegrationObjectSupport
      Subclasses may implement this method to provide component type information.
      Specified by:
      getComponentType in interface NamedComponent
      Overrides:
      getComponentType in class MessageHandlerSupport

    • doInit

      protected void doInit()
      Overrides:
      doInit in class AbstractReplyProducingMessageHandler

    • handleRequestMessage

      protected Object handleRequestMessage(Message<?> requestMessage)
      Description copied from class: AbstractReplyProducingMessageHandler
      Subclasses must implement this method to handle the request Message. The return value may be a Message, a MessageBuilder, or any plain Object. The base class will handle the final creation of a reply Message from any of those starting points. If the return value is null, the Message flow will end here.
      Specified by:
      handleRequestMessage in class AbstractReplyProducingMessageHandler
      Parameters:
      requestMessage - The request message.
      Returns:
      The result of handling the message, or null.

    • onMessage

      public boolean onMessage(Message<?> message)
      Description copied from interface: TcpListener
      Called by a TCPConnection when a new message arrives.
      Specified by:
      onMessage in interface TcpListener
      Parameters:
      message - The message.
      Returns:
      true if the message was intercepted

    • addNewConnection

      public void addNewConnection(TcpConnection connection)
      Description copied from interface: TcpSender
      When we are using sockets owned by a TcpListener, this method is called each time a new connection is made.
