4.2. Example Camel ActiveMQ Component Configuration
Overview
This section describes how to initialize and configure a sample Camel ActiveMQ component instance, which you can then use to define ActiveMQ endpoints in a Camel route. This makes it possible for a Camel route to send or receive messages from a broker.
Prerequisites
The
camel-activemq feature, which defines the bundles required for the Camel ActiveMQ component, is not installed by default. To install the camel-activemq feature, enter the following console command:
JBossFuse:karaf@root> features:install camel-activemq
Sample Camel ActiveMQ component
The following Spring XML sample shows a complete configuration of a Camel ActiveMQ component that has both SSL/TLS security and JAAS authentication enabled. The Camel ActiveMQ component instance is defined to with the
activemqssl bean ID, which means it is associated with the activemqssl scheme (which you use when defining endpoints in a Camel route).
<?xml version="1.0" encoding="UTF-8"?>
<beans ... >
...
<!--
Configure the activemqssl component:
-->
<bean id="jmsConnectionFactory"
class="org.apache.activemq.ActiveMQSslConnectionFactory">
<property name="brokerURL" value="ssl://localhost:61617" />
<property name="userName" value="Username"/>
<property name="password" value="Password"/>
<property name="trustStore" value="/conf/client.ts"/>
<property name="trustStorePassword" value="password"/>
</bean>
<bean id="pooledConnectionFactory"
class="org.apache.activemq.pool.PooledConnectionFactory">
<property name="maxConnections" value="8" />
<property name="maximumActive" value="500" />
<property name="connectionFactory" ref="jmsConnectionFactory" />
</bean>
<bean id="jmsConfig" class="org.apache.camel.component.jms.JmsConfiguration">
<property name="connectionFactory" ref="pooledConnectionFactory"/>
<property name="transacted" value="false"/>
<property name="concurrentConsumers" value="10"/>
</bean>
<bean id="activemqssl"
class="org.apache.activemq.camel.component.ActiveMQComponent">
<property name="configuration" ref="jmsConfig"/>
</bean>
</beans>Sample Camel route
The following Camel route defines a sample endpoint that sends messages securely to the
security.test queue on the broker, using the activemqssl scheme to reference the Camel ActiveMQ component defined in the preceding example:
<?xml version="1.0" encoding="UTF-8"?>
<beans ...>
...
<camelContext xmlns="http://camel.apache.org/schema/spring">
<route>
<from uri="timer://myTimer?fixedRate=true&period=5000"/>
<transform><constant>Hello world!</constant></transform>
<to uri="activemqssl:security.test"/>
</route>
</camelContext>
...
</beans>
