1.pom,xml引入下面的架,版本自己选
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-amqp</artifactId>
<version>2.1.3.RELEASE</version>
</dependency>
2.application.yml,配置连接rabbmitmq连接信息
spring:
rabbitmq:
host: localhost
port: 5672
username: admin
password: admin
3.创建队列
@Configuration public class RabbitMqConfig { @Bean public Queue helloWorldQueue() { return new Queue("helloWorld_queue_test1",true); } }
4.发布消息
@Component public class Sender { @Autowired private RabbitTemplate rabbitTemplate; /** * 发送消息 */ public void send() { String message = "message" + new Date(); rabbitTemplate.convertAndSend("helloWorld_exchange_test1","hello_world_route_key",message); } }
5.订阅消息
@RabbitListener(queues = "helloWorld_queue_test1") @Component public class Receiver { /** * 消费 * @param message */ @RabbitHandler public void helloWorld(String message) { System.out.println("Receiver1:" + message); } }
注意:消息发布了,这个方法会被异步调用
6.测试
pom.xml需要引入如下包:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<version>2.1.3.RELEASE</version>
<scope>test</scope>
</dependency>
@RunWith(SpringRunner.class) @SpringBootTest(classes = RabbitMqServerApplication.class) public class SendTest { @Autowired private Sender sender; @Test public void testSend() { sender.send(); } }
发送的消息成功被消费
控制台输出
