Class LocalizedQueueConnectionFactory

java.lang.Object

org.springframework.xd.dirt.integration.rabbit.LocalizedQueueConnectionFactory

All Implemented Interfaces:

org.springframework.amqp.rabbit.connection.ConnectionFactory, org.springframework.amqp.rabbit.connection.RoutingConnectionFactory

public class LocalizedQueueConnectionFactory
extends java.lang.Object
implements org.springframework.amqp.rabbit.connection.ConnectionFactory, org.springframework.amqp.rabbit.connection.RoutingConnectionFactory

A RoutingConnectionFactory that determines the node on which a queue is located and returns a factory that connects directly to that node. The RabbitMQ management plugin is called over REST to determine the node and the corresponding address for that node is injected into the connection factory. A single instance of each connection factory is retained in a cache. If the location cannot be determined, the default connection factory is returned. This connection factory is typically configured to connect to all the servers in a fail-over mode.

getTargetConnectionFactory(Object) is invoked by the SimpleMessageListenerContainer, when establishing a connection, with the lookup key having the format '[queueName]'.

All ConnectionFactory methods delegate to the default

LocalizedQueueConnectionFactory

public LocalizedQueueConnectionFactory(org.springframework.amqp.rabbit.connection.ConnectionFactory defaultConnectionFactory,
                               java.lang.String[] addresses,
                               java.lang.String[] adminAddresses,
                               java.lang.String[] nodes,
                               java.lang.String vhost,

                               org.springframework.core.io.Resource sslPropertiesLocation)

Parameters:

defaultConnectionFactory - the fallback connection factory to use if the queue can't be located.

addresses - the rabbitmq server addresses (host:port, ...).

adminAddresses - the rabbitmq admin addresses (http://host:port, ...) must be the same length as addresses.

nodes - the rabbitmq nodes corresponding to addresses (rabbit@server1, ...).

vhost - the virtual host.

username - the user name.

password - the password.
