Constructor Details

RabbitStreamMessageHandler

public RabbitStreamMessageHandler(RabbitStreamOperations streamOperations)

Create an instance with the provided RabbitStreamOperations.

Parameters:

streamOperations - the operations.

Method Details

setSendFailureChannel

public void setSendFailureChannel(MessageChannel sendFailureChannel)

Set the failure channel. After a send failure, an ErrorMessage will be sent to this channel with a payload of the exception with the failed message.

Parameters:

sendFailureChannel - the failure channel.

setSendFailureChannelName

public void setSendFailureChannelName(String sendFailureChannelName)

Set the failure channel name. After a send failure, an ErrorMessage will be sent to this channel with a payload of the exception with the failed message.

Parameters:

sendFailureChannelName - the failure channel name.

setSendSuccessChannel

public void setSendSuccessChannel(MessageChannel sendSuccessChannel)

Set the success channel.

Parameters:

sendSuccessChannel - the success channel.

setSendSuccessChannelName

public void setSendSuccessChannelName(String sendSuccessChannelName)

Set the Success channel name.

Parameters:

sendSuccessChannelName - the success channel name.

setSync

public void setSync(boolean sync)

Set to true to wait for a confirmation.

Parameters:

sync - true to wait.

See Also:

• setConfirmTimeout(long)

setConfirmTimeout

public void setConfirmTimeout(long confirmTimeout)

Set the confirm timeout.

Parameters:

confirmTimeout - the timeout.

See Also:

• setSync(boolean)

setHeaderMapper

public void setHeaderMapper(AmqpHeaderMapper headerMapper)

Set a custom AmqpHeaderMapper for mapping request and reply headers. Defaults to DefaultAmqpHeaderMapper.outboundMapper().

Parameters:

headerMapper - the AmqpHeaderMapper to use.

setHeadersMappedLast

public void setHeadersMappedLast(boolean headersMappedLast)

When mapping headers for the outbound message, determine whether the headers are mapped before the message is converted, or afterwards. This only affects headers that might be added by the message converter. When false, the converter's headers win; when true, any headers added by the converter will be overridden (if the source message has a header that maps to those headers). You might wish to set this to true, for example, when using a SimpleMessageConverter with a String payload that contains json; the converter will set the content type to text/plain which can be overridden to application/json by setting the AmqpHeaders.CONTENT_TYPE message header. Default: false.

Parameters:

headersMappedLast - true if headers are mapped after conversion.

getStreamOperations

public RabbitStreamOperations getStreamOperations()

Return the RabbitStreamOperations.

Returns:

the operations.

getSendFailureChannel

protected MessageChannel getSendFailureChannel()

getSendSuccessChannel

protected MessageChannel getSendSuccessChannel()

handleMessageInternal

protected void handleMessageInternal(Message<?> requestMessage)

Specified by:

handleMessageInternal in class AbstractMessageHandler
