public class TcpOutboundGateway
extends AbstractReplyProducingMessageHandler
implements TcpSender, TcpListener, org.springframework.context.SmartLifecycle

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.

SmartLifecycle methods delegate to the underlying AbstractConnectionFactory

2.0

TcpOutboundGateway

public TcpOutboundGateway()

Method Detail

setRequestTimeout

public void setRequestTimeout(long requestTimeout)

Parameters:

requestTimeout - the requestTimeout to set

setRemoteTimeout

public void setRemoteTimeout(long remoteTimeout)

Parameters:

remoteTimeout - the remoteTimeout to set

setSendTimeout

public void setSendTimeout(long sendTimeout)

Description copied from class: AbstractReplyProducingMessageHandler

Set the timeout for sending reply Messages.

Overrides:

setSendTimeout in class AbstractReplyProducingMessageHandler

handleRequestMessage

protected java.lang.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

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

setConnectionFactory

public void setConnectionFactory(AbstractConnectionFactory connectionFactory)

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.

Specified by:

addNewConnection in interface TcpSender

Parameters:

connection - The connection.

removeDeadConnection

public void removeDeadConnection(TcpConnection connection)

Description copied from interface: TcpSender

When we are using sockets owned by a TcpListener, this method is called each time a connection is closed.

Specified by:

removeDeadConnection in interface TcpSender

Parameters:

connection - The connection.

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.

getComponentType

public java.lang.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 AbstractMessageHandler

start

public void start()

Specified by:

start in interface org.springframework.context.Lifecycle

stop

public void stop()

Specified by:

stop in interface org.springframework.context.Lifecycle

isRunning

public boolean isRunning()

Specified by:

isRunning in interface org.springframework.context.Lifecycle

getPhase

public int getPhase()

Specified by:

getPhase in interface org.springframework.context.Phased

isAutoStartup

public boolean isAutoStartup()

Specified by:

isAutoStartup in interface org.springframework.context.SmartLifecycle

stop

public void stop(java.lang.Runnable callback)

Specified by:

stop in interface org.springframework.context.SmartLifecycle

setAutoStartup

public void setAutoStartup(boolean autoStartup)

setPhase

public void setPhase(int phase)

getConnectionFactory

protected AbstractConnectionFactory getConnectionFactory()

Returns:

the connectionFactory
