- 创建生产者工程,pom依赖引入。
<!--
1. 父工程依赖
-->
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.2.2.RELEASE</version>
</parent>
<dependencies>
<!--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>
</dependencies>
- application.yml配置整合
spring:
rabbitmq:
host: 192.168.137.130
port: 5672
username: admin
password: 123456
virtual-host: /
- 创建配置类
@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(){
//代码连编 ctrl+alt+v:补全返回值格式。类似于.var和.castvar
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
noargs():表示不指定参数
*/
@Bean
public Binding bindQueueExchange(@Qualifier("bootQueue") Queue queue,
@Qualifier("bootExchange") Exchange exchange){
return BindingBuilder.bind(queue).to(exchange).with("boot.#").noargs();
}
}
- 创建入口类
@SpringBootApplication
public class ProducerApplication {
public static void main(String[] args) {
SpringApplication.run(ProducerApplication.class);
}
}
- 发送消息
@SpringBootTest
@RunWith(SpringRunner.class)
public class ProducerTest {
@Autowired
private RabbitTemplate rabbitTemplate;
/**
* 第一个参数:交换机名字
* 第二个参数:routingKey
* 第三个参数:发送的消息
*/
@Test
public void testSend(){
rabbitTemplate.convertAndSend(RabbitMQConfig.EXCHANGE_NAME,"boot.haha","mq hello");
}
}
- 搭建消费者工程,pom依赖引入
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.2.2.RELEASE</version>
</parent>
<dependencies>
<!--RabbitMQ 启动依赖-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-amqp</artifactId>
</dependency>
</dependencies>
- application.yml配置整合
spring:
rabbitmq:
host: 192.168.137.130
port: 5672
username: admin
password: 123456
virtual-host: /
- 消息监听器
@Component
public class RabbimtMQListener {
@RabbitListener(queues = "boot_queue")
public void listenerQueue(Message message){
System.out.println(new String(message.getBody()));
}
}
- 创建入口类
@SpringBootApplication
public class ConsumerSpringbootApplication {
public static void main(String[] args) {
SpringApplication.run(ConsumerSpringbootApplication.class, args);
}
}
- 小结:
- SpringBoot提供了快速整合RabbitMQ的方式
- 基本信息在yml中配置,队列交互机以及绑定关系在配置类中使用Bean的方式配置
- 生产端直接注入RabbitTemplate完成消息发送
- 消费端直接使用@RabbitListener完成消息接收
