RabbitMQ-Spring整合RabbitMQ

生产者：

一、rabbitmq.properties

rabbitmq.host=127.0.0.1
rabbitmq.port=5672
rabbitmq.username=guest
rabbitmq.password=guest
rabbitmq.virtual-host=/

二、spring-rabbitmq-producer.xml

    <!--定义广播类型交换机；并绑定上述两个队列-->

    </rabbit:topic-exchange>

    <!--定义rabbitTemplate对象操作可以在代码中方便发送消息-->
    <rabbit:template id="rabbitTemplate" connection-factory="connectionFactory"/>

三、测试类中测试发送消息

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:spring-rabbitmq-producer.xml")
public class SpringRabbitProducer {
    @Autowired
    private RabbitTemplate rabbitTemplate;

    /**
     * 简单模式，发送消息
     */
    @Test
    public void helloWorldTest(){
        rabbitTemplate.convertAndSend("spring_queue","hello world  ...");
    }

    /**
     * fanout，发送消息
     */
    @Test
    public void fanoutTest(){
        rabbitTemplate.convertAndSend("spring_fanout_exchange","","hello fanout  ...");
    }

    /**
     * direct,发送消息
     */
    @Test
    public void directTest(){
        rabbitTemplate.convertAndSend("spring_direct_exchange","direct_queue_2","hello direct ...");
    }

    /**
     *  topics,发送消息
     */
    @Test
    public void topicsTest(){
        rabbitTemplate.convertAndSend("spring_topic_exchange","hi.hello","hello topics");
    }
}

消费者：

一、rabbitmq.properties

rabbitmq.host=127.0.0.1
rabbitmq.port=5672
rabbitmq.username=guest
rabbitmq.password=guest
rabbitmq.virtual-host=/

二、

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/context
       https://www.springframework.org/schema/context/spring-context.xsd
       http://www.springframework.org/schema/rabbit
       http://www.springframework.org/schema/rabbit/spring-rabbit.xsd">
    <!--加载配置文件-->
    <context:property-placeholder location="classpath:rabbitmq.properties"/>

    <!-- 定义rabbitmq connectionFactory -->
    <rabbit:connection-factory id="connectionFactory" host="${rabbitmq.host}"
                               port="${rabbitmq.port}"
                               username="${rabbitmq.username}"
                               password="${rabbitmq.password}"
                               virtual-host="${rabbitmq.virtual-host}"/>

    <bean id="springQueueListener" class="com.rabbitmq.listener.SpringQueueListener"/>
    <bean id="fanoutListener1" class="com.rabbitmq.listener.FanoutListener1"/>
    <bean id="fanoutListener2" class="com.rabbitmq.listener.FanoutListener2"/>
    <bean id="topicListenerStar" class="com.rabbitmq.listener.TopicListenerStar"/>
    <bean id="topicListenerWell" class="com.rabbitmq.listener.TopicListenerWell"/>
    <bean id="topicListenerWell2" class="com.rabbitmq.listener.TopicListenerWell2"/>

    <rabbit:listener-container connection-factory="connectionFactory" auto-declare="true">
        <rabbit:listener ref="springQueueListener" queue-names="spring_queue"/>
        <rabbit:listener ref="fanoutListener1" queue-names="spring_fanout_queue_1"/>
         <rabbit:listener ref="fanoutListener2" queue-names="spring_fanout_queue_2"/>
         <rabbit:listener ref="topicListenerStar" queue-names="spring_topic_queue_star"/>

         <rabbit:listener ref="topicListenerWell2" queue-names="spring_topic_queue_well2"/>
    </rabbit:listener-container>
</beans>

三、监听实现类

public class SpringQueueListener implements MessageListener {
    @Override
    public void onMessage(Message message) {
        System.out.println(new String(message.getBody()));
    }
}
