I have a server which loads the application context with the parameter -ac
camel-server.xml:
<broker:broker useJmx="false" persistent="false" brokerName="localhost">
<broker:transportConnectors>
<broker:transportConnector name="tcp"
uri="tcp://localhost:61616"/>
</broker:transportConnectors>
</broker:broker>
<!-- Connection factory for ActiveMQ endpoints -->
<bean id="connectionFactoryActiveMQ"
class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL" value="vm://localhost"/>
</bean>
<!---------->
<bean id="inOutQueue" class="org.apache.activemq.command.ActiveMQQueue">
<constructor-arg value="inOutQueue"/>
</bean>
<bean id="checkinServices"
class="org.springframework.jms.remoting.JmsInvokerServiceExporter">
<property name="serviceInterface"
value="MyManager"/>
<property name="service">
<bean class="MyManagerImpl"/>
</property>
</bean>
<bean
class="org.springframework.jms.listener.DefaultMessageListenerContainer">
<property name="connectionFactory"
ref="connectionFactoryActiveMQ"/>
<property name="destination" ref="inOutQueue"/>
<property name="maxConcurrentConsumers" value="5"/>
<property name="concurrentConsumers" value="5"/>
<property name="messageListener" ref="checkinServices"/>
</bean>
Then I have a camel-client.xml file which I start up from my Java code.
AbstractApplicationContext context = new
ClassPathXmlApplicationContext("camel-client.xml");
myManager = (MyManager) context.getBean("checkinServices");
myManager.shutdown();
---------------------
So when the client sends a message to a queue defined in camel-client.xml on
an activemq broker which was fired up by camel-server.xml, the server side
processes the message with the services defined to listen on the respective
queue.
In the shutdown method I do the following:
public void shutdown() throws Exception
Main main = Main.getInstance();
if(main != null) {
if(main.getApplicationContext() != null){
main.getApplicationContext().close();
// main.getApplicationContext().registerShutdownHook();
}
}
}
I expect that in the shutdown method I am going to get the instance of Main
that started the camel-server.xml applicatoin context and when I close it
the active mq broker will be closed as well.
Hope you can follow this through.
