RabbitMQ 笔记二
1.Spring 整合RabbitMQ
| 生产者 | 消费者 |

2.创建工程RabbitMQ Producers
spring-rabbitmq-producers
4.0.0
org.example
spring_rabbit_mq
1.0-SNAPSHOT
spring-rabbitmq-producers

UTF-8
org.springframework
spring-context
5.1.7.RELEASE
org.springframework.amqp
spring-rabbit
2.1.8.RELEASE
junit
junit

spring-test
5.1.7.RELEASE
RabbitMQ配置信息：rabbitmq.properties
rabbitmq.host=127.0.0.1
rabbitmq.port=5672
rabbitmq.username=guest
rabbitmq.password=guest
rabbitmq.virtual-host=/
RabbitMQ的配置信息：spring-rabbitmq-producer.xml
rabbitMQ发送消息的代码：ProducerTest.java
package org.example;
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 {
//1.注入rabbitTemplate
@Autowired
private RabbitTemplate rabbitTemplate;
/**
* 测试rabbitMQ的简单工作模式
*/
@Test
public void testHelloWorld(){
//2.发送消息
rabbitTemplate.convertAndSend("spring_queue","hello world spring ....");
}
@Test
public void testFanout(){
//2.发送消息
rabbitTemplate.convertAndSend("spring_fanout_exchange","","spring fanout ....");
}
@Test
public void testTopic(){
//2.发送消息
rabbitTemplate.convertAndSend("spring_topic_exchange","heima.hehe.haha","spring topic ....");
}
}
3.创建工程RabbitMQ Consumers
RabbitMQ consumer的pom文件和spring-rabbitmq-consumers项目的pom文件一致
RabbitMQ Consumer的配置文件：rabbitmq.properties和spring-rabbitmq-consumers项目的rabbitmq.properties文件一致
RabbitMQ Consumer的配置文件：spring-rabbitmq-consumer.xml
编写Listener代码
package org.example.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()));
}
}
监听器在配置文件绑定了对应的队列，当消费者启动起来的时候，监听到消息时，自动消费并打印。
ConsumerTest.java
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 test1() throws InterruptedException {
Thread.sleep(5000);
}
}4.SpringBoot整合RabbitMQ
| 生产者 | 1.创建生产者SpringBoot工程 2.引入依赖 3.编写yml配置，基本信息配置 4.定义交换机，队列及绑定关系的配置类 5.注入RabbitTemplate，调用方法，完成消息发送 |
| 消费者 | 1.创建消费者SpringBoot工程 2.引入依赖 3.编写yml配置，基本信息配置 4.定义监听类，使用@RabbitListener注解完成队列监听 |
| 总结：

5.创建SpringBoot RabbitMQ Producers
pom.xml文件
4.0.0
org.springframework.boot
spring-boot-starter-parent
2.7.9
com.example
springboot-rabbitmq-producers
0.0.1-SNAPSHOT
springboot-rabbitmq-producers
Demo project for Spring Boot Producers
8
org.springframework.boot
spring-boot-starter-amqp
org.springframework.boot
spring-boot-devtools
runtime
true
org.springframework.boot
spring-boot-starter-test
test
org.springframework.amqp
spring-rabbit-test
test
junit
junit
test
org.springframework.boot
spring-boot-maven-plugin
配置文件：application.yml
spring:
rabbitmq:
host: 127.0.0.1
port: 5672
username: guest
password: guest
virtual-host: /配置类：RabbitMQConfig.java
package com.example.config;
import org.springframework.amqp.core.*;
import org.springframework.beans.factory.annotation.Configurable;
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.绑定队列和交换机 Binding
/**
* 绑定
* @param queue 知道绑定哪个队列
* @param exchange 知道哪个交换机
* routingKey 路由键
* @return
*/
@Bean
public Binding bindQueueExchange(@Qualifier("bootQueue") Queue queue,@Qualifier("bootExchange") Exchange exchange) {
return BindingBuilder.bind(queue).to(exchange).with("boot.#").noargs();
}
}
测试方法
package com.example.test;
import com.example.config.RabbitMQConfig;
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.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
@SpringBootTest
@RunWith(SpringRunner.class)
public class ProducerTest {
//1.注入RabbitTemplage
@Autowired
private RabbitTemplate rabbitTemplate;
@Test
public void testSend(){
rabbitTemplate.convertAndSend(RabbitMQConfig.EXCHANGE_NAME,"boot.haha","boot mq hello ~~~");
}
}
6.创建SpringBoot RabbitMQ Consumers
配置文件：pom.xml和application.yml 和RabbitMQ Producer一样
Consumer的Listener
package com.example.listener;
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()));
}
}
测试方法
package com.example.test;
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.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
@SpringBootTest
@RunWith(SpringRunner.class)
public class ConsumerTest {
@Test
public void testReceive(){
System.out.println("接收成功");
}
}
