Spring整合RabbitMQ

這篇具有很好參考價值的文章主要介紹了Spring整合RabbitMQ。希望對大家有所幫助。如果存在錯誤或未考慮完全的地方，請大家不吝賜教，您也可以點擊"舉報違法"按鈕提交疑問。

一、步驟

生產(chǎn)者

① 創(chuàng)建生產(chǎn)者工程

② 添加依賴

③ 配置整合

④ 編寫代碼發(fā)送消息

消費者

① 創(chuàng)建消費者工程

② 添加依賴

③ 配置整合

④ 編寫消息監(jiān)聽器

二、代碼

生產(chǎn)者工程

Spring整合RabbitMQ,rabbitmq,java-rabbitmq,spring,rabbitmq

1.在生產(chǎn)者工程和消費者工程中都導(dǎo)入如下依賴

<dependencies>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>5.1.7.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.amqp</groupId>
        <artifactId>spring-rabbit</artifactId>
        <version>2.1.8.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.12</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-test</artifactId>
        <version>5.1.7.RELEASE</version>
    </dependency>
</dependencies>
<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.0</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
            </configuration>
        </plugin>
    </plugins>
</build>

?2.生產(chǎn)者和消費者導(dǎo)入配置文件? ?rabbitmq.properties

rabbitmq.host=43.143.246.208
rabbitmq.port=5672
rabbitmq.username=root
rabbitmq.password=root
rabbitmq.virtual-host=/itcast

3.生產(chǎn)者核心配置文件??spring-rabbitmq-producer.xml

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

       http://www.springframework.org/schema/rabbit/spring-rabbit.xsd">
    <!--加載配置文件-->
    <context:property-placeholder location="classpath:rabbitmq.properties"/>

    <!-- 定義rabbitmq connectionFactory -->
    <rabbit:connection-factory id="connectionFactory" host="${rabbitmq.host}"
                               port="${rabbitmq.port}"
                               username="${rabbitmq.username}"
                               password="${rabbitmq.password}"
                               virtual-host="${rabbitmq.virtual-host}"/>
    <!--定義管理交換機、隊列-->
    <rabbit:admin connection-factory="connectionFactory"/>

    <!--定義持久化隊列，不存在則自動創(chuàng)建；不綁定到交換機則綁定到默認交換機
    默認交換機類型為direct，名字為：""，路由鍵為隊列的名稱
    -->
    <rabbit:queue id="spring_queue" name="spring_queue" auto-declare="true"/>

    <!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~廣播；所有隊列都能收到消息~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
    <!--定義廣播交換機中的持久化隊列，不存在則自動創(chuàng)建-->
    <rabbit:queue id="spring_fanout_queue_1" name="spring_fanout_queue_1" auto-declare="true"/>

    <!--定義廣播交換機中的持久化隊列，不存在則自動創(chuàng)建-->
    <rabbit:queue id="spring_fanout_queue_2" name="spring_fanout_queue_2" auto-declare="true"/>

    <!--定義廣播類型交換機；并綁定上述兩個隊列-->
    <rabbit:fanout-exchange id="spring_fanout_exchange" name="spring_fanout_exchange" auto-declare="true">
        <rabbit:bindings>
            <rabbit:binding queue="spring_fanout_queue_1"/>
            <rabbit:binding queue="spring_fanout_queue_2"/>
        </rabbit:bindings>
    </rabbit:fanout-exchange>

    <!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~通配符；*匹配一個單詞，#匹配多個單詞 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
    <!--定義廣播交換機中的持久化隊列，不存在則自動創(chuàng)建-->
    <rabbit:queue id="spring_topic_queue_star" name="spring_topic_queue_star" auto-declare="true"/>
    <!--定義廣播交換機中的持久化隊列，不存在則自動創(chuàng)建-->
    <rabbit:queue id="spring_topic_queue_well" name="spring_topic_queue_well" auto-declare="true"/>
    <!--定義廣播交換機中的持久化隊列，不存在則自動創(chuàng)建-->
    <rabbit:queue id="spring_topic_queue_well2" name="spring_topic_queue_well2" auto-declare="true"/>

    <rabbit:topic-exchange id="spring_topic_exchange" name="spring_topic_exchange" auto-declare="true">
        <rabbit:bindings>
            <rabbit:binding pattern="root.*" queue="spring_topic_queue_star"/>
            <rabbit:binding pattern="root.#" queue="spring_topic_queue_well"/>
            <rabbit:binding pattern="itcast.#" queue="spring_topic_queue_well2"/>
        </rabbit:bindings>
    </rabbit:topic-exchange>

    <!--定義rabbitTemplate對象操作可以在代碼中方便發(fā)送消息-->
    <rabbit:template id="rabbitTemplate" connection-factory="connectionFactory"/>
</beans>

4.測試類?ProducerTest

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:spring-rabbitmq-producer.xml")
public class ProducerTest {
    //1.注入 RabbitTemplate
    @Autowired
    private RabbitTemplate rabbitTemplate;

    @Test
    public void testHelloWorld(){
        //2.發(fā)送消息
        rabbitTemplate.convertAndSend("spring_queue","hello world spring....");
    }
    /**
     * 發(fā)送fanout消息
     */
    @Test
    public void testFanout(){
        //2.發(fā)送消息

        rabbitTemplate.convertAndSend("spring_fanout_exchange","","spring fanout....");
    }


    /**
     * 發(fā)送topic消息
     */
    @Test
    public void testTopic(){
        //2.發(fā)送消息

        rabbitTemplate.convertAndSend("spring_topic_exchange","root.hehe.haha","spring topic....");
    }
}

5.運行結(jié)果?

Spring整合RabbitMQ,rabbitmq,java-rabbitmq,spring,rabbitmq

?消費者工程

1、2同上述1、2

3、消費者核心配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:rabbit="http://www.springframework.org/schema/rabbit"
       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">
    <!--加載配置文件-->
    <context:property-placeholder location="classpath:rabbitmq.properties"/>

    <!-- 定義rabbitmq connectionFactory -->
    <rabbit:connection-factory id="connectionFactory" host="${rabbitmq.host}"
                               port="${rabbitmq.port}"
                               username="${rabbitmq.username}"
                               password="${rabbitmq.password}"
                               virtual-host="${rabbitmq.virtual-host}"/>
    <!-- 定義SpringQueueListener -->
    <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">
        <!-- 定義SpringQueueListener 監(jiān)聽哪個隊列-->
        <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="topicListenerWell" queue-names="spring_topic_queue_well"/>-->
<!--        <rabbit:listener ref="topicListenerWell2" queue-names="spring_topic_queue_well2"/>-->
    </rabbit:listener-container>
</beans>

4.類?SpringQueueListener

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

5.測試

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:spring-rabbitmq-comsumer.xml")
public class ConsumerTest {
    @Test
    public void test1(){
        boolean flag = true;
        while (true){

        }
    }

}
