Vert.x Integration

Vert.x is a lightweight, high performance application platform for the JVM that's designed for modern mobile, web, and enterprise applications. Vert.x provides a distributed event bus that allows messages to be sent across vert.x instances and clients. You can now redirect and persist any vert.x messages to ActiveMQ and route those messages to a specified vertx address by configuring ActiveMQ vertx incoming and outgoing vertx connector services.

Configuring a Vertx Incoming Connector Service

Vertx Incoming Connector services receive messages from vertx event bus and route them to a ActiveMQ queue. Such a service can be configured as follows:

<connector-service name="vertx-incoming-connector">
<factory-class>org.apache.activemq.integration.vertx.VertxIncomingConnectorServiceFactory</factory-class>
<param key="host" value="127.0.0.1"/>
<param key="port" value="0"/>
<param key="queue" value="jms.queue.vertxQueue"/>
<param key="vertx-address" value="vertx.in.eventaddress"/>
</connector-service>

Shown are the required params for the connector service:

  • queue. The name of the ActiveMQ queue to send message to.

As well as these required paramaters there are the following optional parameters

  • host. The host name on which the vertx target container is running. Default is localhost.

  • port. The port number to which the target vertx listens. Default is zero.

  • quorum-size. The quorum size of the target vertx instance.

  • ha-group. The name of the ha-group of target vertx instance. Default is activemq.

  • vertx-address. The vertx address to listen to. default is org.apache.activemq.

Configuring a Vertx Outgoing Connector Service

Vertx Outgoing Connector services fetch vertx messages from a ActiveMQ queue and put them to vertx event bus. Such a service can be configured as follows:

<connector-service name="vertx-outgoing-connector">
<factory-class>org.apache.activemq.integration.vertx.VertxOutgoingConnectorServiceFactory</factory-class>
<param key="host" value="127.0.0.1"/>
<param key="port" value="0"/>
<param key="queue" value="jms.queue.vertxQueue"/>
<param key="vertx-address" value="vertx.out.eventaddress"/>
<param key="publish" value="true"/>
</connector-service>

Shown are the required params for the connector service:

  • queue. The name of the ActiveMQ queue to fetch message from.

As well as these required paramaters there are the following optional parameters

  • host. The host name on which the vertx target container is running. Default is localhost.

  • port. The port number to which the target vertx listens. Default is zero.

  • quorum-size. The quorum size of the target vertx instance.

  • ha-group. The name of the ha-group of target vertx instance. Default is activemq.

  • vertx-address. The vertx address to put messages to. default is org.apache.activemq.

  • publish. How messages is sent to vertx event bus. "true" means using publish style. "false" means using send style. Default is false.
