[rabbitmq-discuss] another approach to retrieve message from queue?

Thu Oct 14 07:55:31 BST 2010

I am using spring amqp. Simple POJOs get message automatically upon arrival
of a new message or rabbitMQ's delivery.

*spring configurations for template :*

<!-- Define a RabbitMQ connectionFactory -->
    <bean id="connectionFactory"

class="org.springframework.amqp.rabbit.connection.SingleConnectionFactory">
        <constructor-arg value="localhost" />
        <property name="username" value="guest" />
        <property name="password" value="guest" />
    </bean>

*use that template in ur POJO to become a "magical" consumer:*

<bean id="msgHandler" class="com.xyz.MsgHandler" />

    <bean id="msgHandlerAdaptor"
class="org.springframework.amqp.rabbit.listener.adapter.MessageListenerAdapter">
        <constructor-arg ref="msgHandler" />
    </bean>

    <bean id="msgListener"
class="org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer"
        p:connectionFactory-ref="connectionFactory" p:queueName="Queue1"
p:autoAck="false" p:concurrentConsumers="20"
p:messageListener-ref="msgHandlerAdaptor" />

*Bean has*

    public void handleMessage(String msg) {

    }

That's it !!!
