一、步骤

生产者

① 创建生产者工程
② 添加依赖
③ 配置整合
④ 编写代码发送消息

消费者

① 创建消费者工程
② 添加依赖
③ 配置整合
④ 编写消息监听器

二、代码

生产者工程

1.在生产者工程和消费者工程中都导入如下依赖

java 复制代码

<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.生产者和消费者导入配置文件 rabbitmq.properties

java 复制代码

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

3.生产者核心配置文件 spring-rabbitmq-producer.xml

java 复制代码

    <!--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}"/>
    <!--定义管理交换机、队列-->
    <rabbit:admin connection-factory="connectionFactory"/>

    <!--定义持久化队列，不存在则自动创建；不绑定到交换机则绑定到默认交换机
    默认交换机类型为direct，名字为：""，路由键为队列的名称
    -->
    <rabbit:queue id="spring_queue" name="spring_queue" auto-declare="true"/>

    <!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~广播；所有队列都能收到消息~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
    <!--定义广播交换机中的持久化队列，不存在则自动创建-->
    <rabbit:queue id="spring_fanout_queue_1" name="spring_fanout_queue_1" auto-declare="true"/>

    <!--定义广播交换机中的持久化队列，不存在则自动创建-->
    <rabbit:queue id="spring_fanout_queue_2" name="spring_fanout_queue_2" auto-declare="true"/>

    <!--定义广播类型交换机；并绑定上述两个队列-->
    <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；*匹配一个单词，#匹配多个单词 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
    <!--定义广播交换机中的持久化队列，不存在则自动创建-->
    <rabbit:queue id="spring_topic_queue_star" name="spring_topic_queue_star" auto-declare="true"/>
    <!--定义广播交换机中的持久化队列，不存在则自动创建-->
    <rabbit:queue id="spring_topic_queue_well" name="spring_topic_queue_well" auto-declare="true"/>
    <!--定义广播交换机中的持久化队列，不存在则自动创建-->
    <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"/>
</beans>

4.测试类 ProducerTest

java 复制代码

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

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


    /**
     * 发送topic消息
     */
    @Test
    public void testTopic(){
        //2.发送消息

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

5.运行结果

消费者工程

1、2同上述1、2

3、消费者核心配置文件

java 复制代码

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

       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}"/>
    <!-- 定义SpringQueueListener -->

<!--    <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">
        <!-- 定义SpringQueueListener 监听哪个队列-->
        <rabbit:listener ref="springQueueListener" queue-names="spring_queue"/>
<!--        <rabbit:listener ref="fanoutListener1" queue-names="spring_fanout_queue_1"/>-->

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

4.类 SpringQueueListener

java 复制代码

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

5.测试

java 复制代码

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

        }
    }

}
