SpringBoot整合RabbitMQ，笔记整理

1创建生产者工程springboot-rabbitmq-produce

2.修改pom.xml文件

<!--父工程-->
<parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.6.0</version><relativePath/>
</parent>
<dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><!--2. rabbitmq--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-amqp</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId></dependency><dependency><groupId>junit</groupId><artifactId>junit</artifactId><scope>test</scope></dependency>
</dependencies>

3.启动类  com.javacto.ProducerApplication

package com.javacto;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class ProducerApplication {public static void main(String[] args) {SpringApplication.run(ProducerApplication.class, args);}
}

4.创建application.yml

# 配置RabbitMQ的基本信息  ip 端口 username  password..
spring:rabbitmq:host: 192.168.64.139 # ipport: 5672username: javactopassword: javactovirtual-host: /javacto

5.创建RabbitMQ队列与交换机绑定的配置类com.javacto.rabbitmq.config.RabbitMQConfig

import org.springframework.amqp.core.*;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class RabbitMQConfig {public static final String EXCHANGE_NAME = "boot_topic_exchange";public static final String QUEUE_NAME = "boot_queue";//1.交换机@Bean("bootExchange")public Exchange bootExchange(){return ExchangeBuilder.topicExchange(EXCHANGE_NAME).durable(true).build();}//2.Queue 队列@Bean("bootQueue")public Queue bootQueue(){return QueueBuilder.durable(QUEUE_NAME).build();}//3. 队列和交互机绑定关系 Binding/*1. 知道哪个队列2. 知道哪个交换机3. routing key*/@Beanpublic Binding bindQueueExchange(@Qualifier("bootQueue") Queue queue, @Qualifier("bootExchange") Exchange exchange){//  bind(队列).to(交换机).with(routingKey).noargs(不需要指定参数) 如果需要指它就.add()return BindingBuilder.bind(queue).to(exchange).with("boot.#").noargs();}
}

6.创建com.javacto.test.ProducerTest 然后运行

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 ProductTest {//1.注入RabbitTemplate@Autowiredprivate RabbitTemplate rabbitTemplate;//2.发送消息@Testpublic  void testHelloWorld(){rabbitTemplate.convertAndSend("spring_queue","hello world spring222");}//2.发送消息@Testpublic  void testFanout(){rabbitTemplate.convertAndSend("spring_fanout_exchange","","spring fanout...");}//2.发送消息@Testpublic  void testTopics(){rabbitTemplate.convertAndSend("spring_topic_exchange","javacto.add","spring topic...");}
}

2.修改pom.xml文件

</dependencies>

3.启动类  com.javacto.ProducerApplication

package com.javacto;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class ProducerApplication {public static void main(String[] args) {SpringApplication.run(ProducerApplication.class, args);}
}

4.创建application.yml

# 配置RabbitMQ的基本信息  ip 端口 username  password..
spring:rabbitmq:host: 192.168.64.139 # ipport: 5672username: javactopassword: javactovirtual-host: /javacto

5.创建RabbitMQ队列与交换机绑定的配置类com.javacto.rabbitmq.config.RabbitMQConfig

package com.javacto.mq;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;
@Component
public class RabbitMQListener {@RabbitListener(queues = "boot_queue")public  void listenerQueue(Message message){System.out.println(new String(message.getBody()));}
}

6.启动springBoot工程即可
