Constructor Detail

RabbitStreamMessageHandler

public RabbitStreamMessageHandler(org.springframework.rabbit.stream.producer.RabbitStreamOperations streamOperations)

Create an instance with the provided RabbitStreamOperations.

Parameters:

streamOperations - the operations.

Method Detail

setSuccessCallback

public void setSuccessCallback(org.springframework.util.concurrent.SuccessCallback<org.springframework.messaging.Message<?>> successCallback)

Set a callback to be invoked when a send is successful.

Parameters:

successCallback - the callback.

setFailureCallback

public void setFailureCallback(RabbitStreamMessageHandler.FailureCallback failureCallback)

Set a callback to be invoked when a send fails.

Parameters:

failureCallback - the callback.

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(org.springframework.integration.amqp.support.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 org.springframework.rabbit.stream.producer.RabbitStreamOperations getStreamOperations()

Return the RabbitStreamOperations.

Returns:

the operations.
