public class PollableAmqpChannel
extends AbstractAmqpChannel
implements PollableChannel, ExecutorChannelInterceptorAware
A
PollableChannel
implementation that is backed by an AMQP Queue.
Messages will be sent to the default (no-name) exchange with that Queue's
name as the routing key.- Since:

Constructor Details

PollableAmqpChannel
Construct an instance with the supplied name, template and default header mappers used if the template is aRabbitTemplate
and the message is mapped.- Parameters:
channelName
- the channel name.amqpTemplate
- the template.- See Also:
-
PollableAmqpChannel
public PollableAmqpChannel(String channelName, AmqpTemplate amqpTemplate, AmqpHeaderMapper outboundMapper, AmqpHeaderMapper inboundMapper) Construct an instance with the supplied name, template and header mappers.- Parameters:
channelName
- the channel name.amqpTemplate
- the template.outboundMapper
- the outbound mapper.inboundMapper
- the inbound mapper.- Since:
- 4.3
- See Also:
-
-
Method Details
-
setQueueName
Provide an explicitly configured queue name. If this is not provided, then a Queue will be created implicitly with the channelName as its name. The implicit creation will require that either an AmqpAdmin instance has been provided or that the configured AmqpTemplate is an instance of RabbitTemplate.- Parameters:
queueName
- The queue name.
-
setAmqpAdmin
Provide an instance of AmqpAdmin for implicitly declaring Queues if the queueName is not provided. When providing a RabbitTemplate implementation, this is not strictly necessary since a RabbitAdmin instance can be created from the template's ConnectionFactory reference.- Parameters:
amqpAdmin
- The amqp admin.
-
getRoutingKey
Description copied from class:AbstractAmqpChannel
Subclasses may override this method to return a routing key. By default, there will be no routing key (empty string).- Overrides:
getRoutingKey
in classAbstractAmqpChannel
- Returns:
- The routing key.
-

Subclasses may implement this for initialization logic.- Overrides:
onInit
in classAbstractAmqpChannel

setInterceptors
Description copied from class:AbstractMessageChannel
Set the list of channel interceptors. This will clear any existing interceptors.- Specified by:

in classAbstractMessageChannel
- Parameters:
interceptors
- The list of interceptors.
-
addInterceptor
Description copied from class:AbstractMessageChannel

index
- The index to add interceptor.interceptor
- The interceptor.
