public class TcpInboundGateway extends MessagingGatewaySupport implements TcpListener, TcpSender, ClientModeCapable, OrderlyShutdownCapable
Inbound Gateway using a server connection factory - threading is controlled by the factory. For java.net connections, each socket can process only one message at a time. For java.nio connections, messages may be multiplexed but the client will need to provide correlation logic. If the client is a TcpOutboundGateway multiplexing is not used, but multiple concurrent connections can be used if the connection factory uses single-use connections. For true asynchronous bi-directional communication, a pair of inbound / outbound channel adapters should be used.

      Specified by:
      removeDeadConnection in interface TcpSender
      Parameters:
      connection - The connection.
    • getComponentType

      public String getComponentType()
      Description copied from class: IntegrationObjectSupport
      Subclasses may implement this method to provide component type information.
