11.13. JMS Routing
JMS Routing
JMS routing is performed via the jms:router configuration from the http://www.milyn.org/xsd/smooks/jms-routing-1.2.xsd configuration namespace. The following is an example jms:router configuration that routes an orderItem_xml bean to a JMS Queue named smooks.exampleQueue:
<?xml version="1.0"?>
<smooks-resource-list xmlns="http://www.milyn.org/xsd/smooks-1.1.xsd"
xmlns:core="http://www.milyn.org/xsd/smooks/smooks-core-1.3.xsd"
xmlns:jms="http://www.milyn.org/xsd/smooks/jms-routing-1.2.xsd"
xmlns:ftl="http://www.milyn.org/xsd/smooks/freemarker-1.1.xsd">
<!--
Filter the message using the SAX Filter (i.e. not DOM, so no
intermediate DOM, so we can process huge messages...
-->
<core:filterSettings type="SAX" />
(1) <resource-config selector="order,order-item">
<resource>org.milyn.delivery.DomModelCreator</resource>
</resource-config>
(2) <jms:router routeOnElement="order-item" beanId="orderItem_xml" destination="smooks.exampleQueue">
<jms:message>
<!-- Need to use special FreeMarker variable ".vars" -->
<jms:correlationIdPattern>${order.@id}-${.vars["order-item"].@id}</jms:correlationIdPattern>
</jms:message>
<jms:highWaterMark mark="3"/>
</jms:router>
(3) <ftl:freemarker applyOnElement="order-item">
<!--
Note in the template that we need to use the special FreeMarker variable ".vars"
because of the hyphenated variable names ("order-item"). See http://freemarker.org/docs/ref_specvar.html.
-->
<ftl:template>/orderitem-split.ftl</ftl:template>
<ftl:use>
<!-- Bind the templating result into the bean context, from where
it can be accessed by the JMSRouter (configured above). -->
<ftl:bindTo id="orderItem_xml"/>
</ftl:use>
</ftl:freemarker>
</smooks-resource-list>
In this case, we route the result of a FreeMarker templating operation to the JMS Queue (that is, as a String). We could also have routed a full Object Model, in which case it would be routed as a Serialized ObjectMessage.
