SpringBoot整合RabbitMQ

SpringBoot整合RabbitMQ，生产者
（1）创建maven项目
（2）引入依赖

<parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.2.2.RELEASE</version></parent><dependencies><!-- spring的上下文 --><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId></dependency><!-- spring整合amqp插件包 --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-amqp</artifactId></dependency><!-- 单元测试包 --><dependency><groupId>junit</groupId><artifactId>junit</artifactId></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId><scope>test</scope></dependency></dependencies>

（3）创建 rabbitmq.properties 配置文件

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

（4）创建 spring-rabbitmq-producer.xml 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"><!-- 加载配置文件 --><context:property-placeholder location="classpath:rabbitmq.properties"/><!-- 定义rabbitmq连接工厂 --><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，所有独立额都能收到消息 --><!-- 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"/><rabbit:queue id="spring_fanout_queue_2"name="spring_fanout_queue_2" auto-declare="true"/><!-- 定义广播交换机，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_start"name="spring_topic_queue_start" auto-declare="true"/><rabbit:queue id="spring_topic_queue_swell"name="spring_topic_queue_swell" auto-declare="true"/><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="juexing.*"queue="spring_topic_queue_start" /><rabbit:binding pattern="juexing.#"queue="spring_topic_queue_swell"/><rabbit:binding pattern="test.#"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>

（5）编写测试代码，发送消息

package com.juexing;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.amqp.rabbit.core.RabbitTemplate;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:spring-rabbitmq-producer.xml")
public class ProducerTest {

    @Autowired
    private RabbitTemplate rabbitTemplate;

    @Test
    public void testHelloWorld(){
        rabbitTemplate.convertAndSend("spring_queue", "hello world spring...");}

    @Test
    public void testFanout(){
        rabbitTemplate.convertAndSend("spring_fanout_exchange", "","spring_fanout...");}

    @Test
    public void testTopic(){
        rabbitTemplate.convertAndSend("spring_topic_exchange", "juexing.erci","spring_testTopic...");}}

（6）项目结构图展示
在这里插入图片描述
（7）运行测试代码，查看效果

两个交换机

在这里插入图片描述
spring_fanout_exchange交换机，绑定了spring_fanout_queue1、spring_fanout_queue2 两个消息队列

spring_topic_exchange交换机，绑定了spring_topic_queue_start、spring_topic_queue_swell、spring_topic_queue_well2

6个消息队列，与未消费的消息。

SpringBoot整合RabbitMQ，消费者
（1）创建maven项目
（2）引入依赖

<parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.2.2.RELEASE</version></parent><dependencies><!-- spring的上下文 --><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId></dependency><!-- spring整合amqp插件包 --><dependency><groupId>org.springframework.amqp</groupId><artifactId>spring-rabbit</artifactId></dependency><!-- 单元测试包 --><dependency><groupId>junit</groupId><artifactId>junit</artifactId></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId><scope>test</scope></dependency></dependencies>

（3）创建 rabbitmq.properties 配置文件

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

（4）创建 spring-rabbitmq-consumer.xml 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

（5）编写监听类，消费消息

package com.juexing.listener;import org.springframework.amqp.core.Message;import org.springframework.amqp.core.MessageListener;

public class SpringQueueListener implements MessageListener {

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

（6）编写测试类

package com.juexing;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:spring-rabbitmq-consumer.xml")
public class ConsumerTest {

    @Test
    public void testSpringQueue(){}}

（7）运行测试类，打印消息
