Field Details

CONSOLIDATED_HEADERS

public static final String CONSOLIDATED_HEADERS

Header containing List<Map<String, Object> headers when batch mode is AmqpInboundChannelAdapter.BatchMode.EXTRACT_PAYLOADS_WITH_HEADERS.

See Also:

• Constant Field Values

Constructor Details

AmqpInboundChannelAdapter

public AmqpInboundChannelAdapter(AbstractMessageListenerContainer listenerContainer)

AmqpInboundChannelAdapter

public AmqpInboundChannelAdapter(MessageListenerContainer listenerContainer)

Construct an instance using the provided container.

Parameters:

listenerContainer - the container.

Method Details

setMessageConverter

public void setMessageConverter(MessageConverter messageConverter)

setHeaderMapper

public void setHeaderMapper(AmqpHeaderMapper headerMapper)

setRetryTemplate

public void setRetryTemplate(org.springframework.retry.support.RetryTemplate retryTemplate)

Set a RetryTemplate to use for retrying a message delivery within the adapter. Unlike adding retry at the container level, this can be used with an ErrorMessageSendingRecoverer RecoveryCallback to publish to the error channel after retries are exhausted. You generally should not configure an error channel when using retry here, use a RecoveryCallback instead.

Parameters:

retryTemplate - the template.

Since:

4.3.10.

See Also:

• setRecoveryCallback(RecoveryCallback)

setRecoveryCallback

public void setRecoveryCallback(org.springframework.retry.RecoveryCallback<?> recoveryCallback)

Set a RecoveryCallback when using retry within the adapter. Mutually exclusive with setMessageRecoverer(MessageRecoverer).

Parameters:

recoveryCallback - the callback.

Since:

4.3.10

See Also:

• setRetryTemplate(RetryTemplate)

setMessageRecoverer

public void setMessageRecoverer(MessageRecoverer messageRecoverer)

Configure a MessageRecoverer for retry operations. A more AMQP-specific convenience instead of setRecoveryCallback(RecoveryCallback).

Parameters:

messageRecoverer - the MessageRecoverer to use.

Since:

5.5

setBatchingStrategy

public void setBatchingStrategy(BatchingStrategy batchingStrategy)

Set a batching strategy to use when de-batching messages created by a batching producer (such as the BatchingRabbitTemplate). Default is SimpleBatchingStrategy.

Parameters:

batchingStrategy - the strategy.

Since:

5.2

setBindSourceMessage

public void setBindSourceMessage(boolean bindSourceMessage)

Set to true to bind the source message in the header named IntegrationMessageHeaderAccessor.SOURCE_DATA.

Parameters:

bindSourceMessage - true to bind.

Since:

5.1.6

setBatchMode

public void setBatchMode(AmqpInboundChannelAdapter.BatchMode batchMode)

When the listener container is configured with consumerBatchEnabled, set the payload type for messages generated for the batches. Default is AmqpInboundChannelAdapter.BatchMode.MESSAGES.

Parameters:

batchMode - the batch mode.

Since:

5.3

getComponentType

public String getComponentType()

Description copied from class: IntegrationObjectSupport

Subclasses may implement this method to provide component type information.

Specified by:

getComponentType in interface NamedComponent

Overrides:

Returns:

The number of active messages if available.

getErrorMessageAttributes

protected AttributeAccessor getErrorMessageAttributes(Message<?> message)

Description copied from class: MessageProducerSupport

Overrides:

getErrorMessageAttributes in class MessageProducerSupport

Parameters:

message - the message.

Returns:

the attributes.
