Method Details

setTaskExecutor

public void setTaskExecutor(Executor taskExecutor)

setMessageConverter

public void setMessageConverter(MessageConverter messageConverter)

Description copied from class: AbstractMessageChannel

Specify the MessageConverter to use when trying to convert to one of this channel's supported datatypes (in order) for a Message whose payload does not already match.

Note: only the MessageConverter.fromMessage(Message, Class) method is used. If the returned object is not a Message, the inbound headers will be copied; if the returned object is a Message, it is expected that the converter will have fully populated the headers; no further action is performed by the channel. If null is returned, conversion to the next datatype (if any) will be attempted. Defaults to a DefaultDatatypeChannelMessageConverter.

Overrides:

setMessageConverter in class AbstractMessageChannel

Parameters:

messageConverter - The message converter.

setSerializer

public void setSerializer(RedisSerializer<?> serializer)

setMaxSubscribers

public void setMaxSubscribers(int maxSubscribers)

Specify the maximum number of subscribers supported by the channel's dispatcher.

Parameters:

maxSubscribers - The maximum number of subscribers allowed.

subscribe

public boolean subscribe(MessageHandler handler)

Specified by:

subscribe in interface SubscribableChannel

unsubscribe

public boolean unsubscribe(MessageHandler handler)

Specified by:

unsubscribe in interface SubscribableChannel

doSend

protected boolean doSend(Message<?> message,
 long arg1)

Description copied from class: AbstractMessageChannel

Subclasses must implement this method. A non-negative timeout indicates how long to wait if the channel is at capacity (if the value is 0, it must return immediately with or without success). A negative timeout value indicates that the method should block until either the message is accepted or the blocking thread is interrupted.

Specified by:

doSend in class AbstractMessageChannel

Parameters:

message - The message.

arg1 - The timeout.

Returns:

true if the send was successful.

onInit

public void onInit()

Description copied from class: IntegrationObjectSupport

Subclasses may implement this for initialization logic.

Overrides:

onInit in class AbstractMessageChannel

isAutoStartup

public boolean isAutoStartup()

Specified by:

isAutoStartup in interface SmartLifecycle

getPhase

public int getPhase()

Specified by:

getPhase in interface Phased

Specified by:

getPhase in interface SmartLifecycle

isRunning

public boolean isRunning()

Specified by:

isRunning in interface Lifecycle

Specified by:

isRunning in interface ManageableLifecycle

start

public void start()

Specified by:

start in interface Lifecycle

Specified by:

start in interface ManageableLifecycle

stop

public void stop()

Specified by:

stop in interface Lifecycle

Specified by:

stop

public void stop(Runnable callback)

Specified by:

destroy

public void destroy()

Specified by:

destroy in interface DisposableBean

Specified by:

destroy in interface IntegrationManagement

Overrides:

destroy in class AbstractMessageChannel
