Class RabbitTemplate

java.lang.Object

org.springframework.amqp.rabbit.connection.RabbitAccessor

org.springframework.amqp.rabbit.core.RabbitTemplate

All Implemented Interfaces:

AmqpTemplate, MessageListener, RabbitOperations, PublisherCallbackChannel.Listener, InitializingBean

public class RabbitTemplate
extends RabbitAccessor
implements RabbitOperations, MessageListener, PublisherCallbackChannel.Listener

Helper class that simplifies synchronous RabbitMQ access (sending and receiving messages).

The default settings are for non-transactional messaging, which reduces the amount of data exchanged with the broker. To use a new transaction for every send or receive set the channelTransacted flag. To extend the transaction over multiple invocations (more efficient), you can use a Spring transaction to bracket the calls (with channelTransacted=true as well).

The only mandatory property is the ConnectionFactory. There are strategies available for converting messages to and from Java objects ( MessageConverter) and for converting message headers (known as message properties in AMQP, see MessagePropertiesConverter ). The defaults probably do something sensible for typical use cases, as long as the message content-type is set appropriately.

The "send" methods all have overloaded versions that allow you to explicitly target an exchange and a routing key, or you can set default values to be used in all send operations. The plain "receive" methods allow you to explicitly target a queue to receive from, or you can set a default value for the template that applies to all explicit receives. The convenience methods for send and receive use the sender defaults if no exchange or routing key is specified, but they always use a temporary queue for the receive leg, so the default queue is ignored.

Constructor Detail

RabbitTemplate

public RabbitTemplate()

Convenient constructor for use with setter injection. Don't forget to set the connection factory.

RabbitTemplate

public RabbitTemplate(ConnectionFactory connectionFactory)

Create a rabbit template with default strategies and settings.

Parameters:

connectionFactory - the connection factory to use

Method Detail

initDefaultStrategies

protected void initDefaultStrategies()

Set up the default strategies. Subclasses can override if necessary.

setExchange

public void setExchange(String exchange)

The name of the default exchange to use for send operations when none is specified. Defaults to "" which is the default exchange in the broker (per the AMQP specification).

Parameters:

exchange - the exchange name to use for send operations

setRoutingKey

public void setRoutingKey(String routingKey)

The value of a default routing key to use for send operations when none is specified. Default is empty which is not helpful when using the default (or any direct) exchange, but fine if the exchange is a headers exchange for instance.

Parameters:

routingKey - the default routing key to use for send operations

setQueue

public void setQueue(String queue)

The name of the default queue to receive messages from when none is specified explicitly.

Parameters:

queue - the default queue name to use for receive

setEncoding

public void setEncoding(String encoding)

The encoding to use when inter-converting between byte arrays and Strings in message properties.

Parameters:

encoding - the encoding to set

setReplyQueue

public void setReplyQueue(Queue replyQueue)

A queue for replies; if not provided, a temporary exclusive, auto-delete queue will be used for each reply.

Parameters:

replyQueue - the replyQueue to set

setReplyTimeout

public void setReplyTimeout(long replyTimeout)

Specify the timeout in milliseconds to be used when waiting for a reply Message when using one of the sendAndReceive methods. The default value is defined as DEFAULT_REPLY_TIMEOUT. A negative value indicates an indefinite timeout. Not used in the plain receive methods because there is no blocking receive operation defined in the protocol.

Parameters:

replyTimeout - the reply timeout in milliseconds

See Also:

sendAndReceive(String, String, Message), convertSendAndReceive(String, String, Object)

setMessageConverter

public void setMessageConverter(MessageConverter messageConverter)

Set the message converter for this template. Used to resolve Object parameters to convertAndSend methods and Object results from receiveAndConvert methods.

The default converter is a SimpleMessageConverter, which is able to handle byte arrays, Strings, and Serializable Objects depending on the message content type header.

See Also:

convertAndSend(java.lang.Object), receiveAndConvert(), SimpleMessageConverter

setMessagePropertiesConverter

public void setMessagePropertiesConverter(MessagePropertiesConverter messagePropertiesConverter)

Set the MessagePropertiesConverter for this template. This converter is used to convert between raw byte content in the message headers and plain Java objects. In particular there are limitations when dealing with very long string headers, which hopefully are rare in practice, but if you need to use long headers you might need to inject a special converter here.

getMessageConverter

public MessageConverter getMessageConverter()

Return the message converter for this template. Useful for clients that want to take advantage of the converter in ChannelCallback implementations.

setConfirmCallback

public void setConfirmCallback(RabbitTemplate.ConfirmCallback confirmCallback)

setReturnCallback

public void setReturnCallback(RabbitTemplate.ReturnCallback returnCallback)

setMandatory

public void setMandatory(boolean mandatory)

setImmediate

@Deprecated
public void setImmediate(boolean immediate)

Deprecated. - RabbitMQ no longer supports this option when publishing messages.

setCorrelationKey

public void setCorrelationKey(String correlationKey)

If set to 'correlationId' (default) the correlationId property will be used; otherwise the supplied key will be used.

Parameters:

correlationKey - the correlationKey to set

getUnconfirmed

public Collection<CorrelationData> getUnconfirmed(long age)

Gets unconfirmed correlatiom data older than age and removes them.

Parameters:

age - in millseconds

Returns:

the collection of correlation data for which confirms have not been received.
