python rabbitmq 将消息赋给白能量 rabbitmqtemplate发送消息

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
