Class AsyncRabbitTemplate

java.lang.Object
org.springframework.amqp.rabbit.AsyncRabbitTemplate
All Implemented Interfaces:
AsyncAmqpTemplate, MessageListener, RabbitTemplate.ConfirmCallback, RabbitTemplate.ReturnsCallback, ChannelAwareMessageListener, Aware, BeanNameAware, Lifecycle, Phased, SmartLifecycle
public class AsyncRabbitTemplate extends Object implements AsyncAmqpTemplate, ChannelAwareMessageListener, RabbitTemplate.ReturnsCallback, RabbitTemplate.ConfirmCallback, BeanNameAware, SmartLifecycle
Provides asynchronous send and receive operations returning a CompletableFuture allowing the caller to obtain the reply later, using get() or a callback.

When confirms are enabled, the future has a confirm property which is itself a CompletableFuture. If the reply is received before the publisher confirm, the confirm is discarded since the reply implicitly indicates the message was published.

Returned (undeliverable) request messages are presented as a AmqpMessageReturnedException cause of an ExecutionException.

Internally, the template uses a RabbitTemplate and an AbstractMessageListenerContainer either provided or constructed internally (a SimpleMessageListenerContainer). If an external RabbitTemplate is provided and confirms/returns are enabled, it must not previously have had callbacks registered because this object needs to be the callback.

    • AsyncRabbitTemplate

      public AsyncRabbitTemplate(ConnectionFactory connectionFactory, String exchange, String routingKey, String replyQueue)
      Construct an instance using the provided arguments. Replies will be routed to the default exchange using the reply queue name as the routing key.
      Parameters:
      connectionFactory - the connection factory.
      exchange - the default exchange to which requests will be sent.
      routingKey - the default routing key.
      replyQueue - the name of the reply queue to listen for replies.

    • AsyncRabbitTemplate

      public AsyncRabbitTemplate(ConnectionFactory connectionFactory, String exchange, String routingKey, String replyQueue, String replyAddress)
      Construct an instance using the provided arguments. If 'replyAddress' is null, replies will be routed to the default exchange using the reply queue name as the routing key. Otherwise it should have the form exchange/routingKey and must cause messages to be routed to the reply queue.
      Parameters:
      connectionFactory - the connection factory.
      exchange - the default exchange to which requests will be sent.
      routingKey - the default routing key.
      replyQueue - the name of the reply queue to listen for replies.
      replyAddress - the reply address (exchange/routingKey).

    • AsyncRabbitTemplate

      public AsyncRabbitTemplate(RabbitTemplate template, AbstractMessageListenerContainer container)
      Construct an instance using the provided arguments. The first queue the container is configured to listen to will be used as the reply queue. Replies will be routed using the default exchange with that queue name as the routing key.
      Parameters:
      template - a RabbitTemplate
      container - a AbstractMessageListenerContainer.

    • AsyncRabbitTemplate

      public AsyncRabbitTemplate(RabbitTemplate template, AbstractMessageListenerContainer container, String replyAddress)
      Construct an instance using the provided arguments. The first queue the container is configured to listen to will be used as the reply queue. If 'replyAddress' is null, replies will be routed using the default exchange with that queue name as the routing key. Otherwise it should have the form exchange/routingKey and must cause messages to be routed to the reply queue.
      Parameters:
      template - a RabbitTemplate.
      container - a AbstractMessageListenerContainer.
      replyAddress - the reply address.
