Spring整合RabbitMQ

一、步骤

生产者

消费者

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

    
        org.springframework
        spring-context
        5.1.7.RELEASE
    
    
        org.springframework.amqp
        spring-rabbit
        2.1.8.RELEASE
    
    
        junit
        junit
        4.12
    
    
        org.springframework
        spring-test
        5.1.7.RELEASE
    
    
        
            org.apache.maven.plugins
            maven-compiler-plugin
            3.8.0
            
                1.8
                1.8
            
        
    

 2.生产者和消费者 导入配置文件   rabbitmq.properties

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

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

"1.0" encoding="UTF-8"?>
"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">
    
    "classpath:rabbitmq.properties"/>
 
    
    "connectionFactory" host="${rabbitmq.host}"
                               port="${rabbitmq.port}"
                               username="${rabbitmq.username}"
                               password="${rabbitmq.password}"
                               virtual-host="${rabbitmq.virtual-host}"/>
    
    "connectionFactory"/>
 
    
    "spring_queue" name="spring_queue" auto-declare="true"/>
 
    
    
    "spring_fanout_queue_1" name="spring_fanout_queue_1" auto-declare="true"/>
 
    
    "spring_fanout_queue_2" name="spring_fanout_queue_2" auto-declare="true"/>
 
    
    "spring_fanout_exchange" name="spring_fanout_exchange" auto-declare="true">
        
            "spring_fanout_queue_1"/>
            "spring_fanout_queue_2"/>
        
    
 
    
    
    "spring_topic_queue_star" name="spring_topic_queue_star" auto-declare="true"/>
    
    "spring_topic_queue_well" name="spring_topic_queue_well" auto-declare="true"/>
    
    "spring_topic_queue_well2" name="spring_topic_queue_well2" auto-declare="true"/>
 
    "spring_topic_exchange" name="spring_topic_exchange" auto-declare="true">
        
            "root.*" queue="spring_topic_queue_star"/>
            "root.#" queue="spring_topic_queue_well"/>
            "itcast.#" queue="spring_topic_queue_well2"/>
        
    
 
    
    "rabbitTemplate" connection-factory="connectionFactory"/>

4.测试类 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.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

"1.0" encoding="UTF-8"?>
"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">
    
    "classpath:rabbitmq.properties"/>
 
    
    "connectionFactory" host="${rabbitmq.host}"
                               port="${rabbitmq.port}"
                               username="${rabbitmq.username}"
                               password="${rabbitmq.password}"
                               virtual-host="${rabbitmq.virtual-host}"/>
    
    "springQueueListener" class="com.rabbitmq.listener.SpringQueueListener"/>
 
    "connectionFactory" auto-declare="true">
        
        "springQueueListener" queue-names="spring_queue"/>
    

4.类 SpringQueueListener

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

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