RabbitMQ---SpringBoot整合RabbitMQ(Fanout交换器)

Fanout交换器特点：

各个队列与Topic交换器之间没有路由键绑定配置，发送者发送一条消息给交换器，只要与此交换器绑定的队列，都会接收到消息。

生产者module，只需要指定交换器，发送消息也只需要指定交换器即可

<dependency>

</dependency>

application.properties配置RabbitMQ信息

#RabbitMQ基本信息
spring.rabbitmq.host=182.61.40.184
spring.rabbitmq.port=5672
spring.rabbitmq.username=rabbitmq
spring.rabbitmq.password=rabbitmq

#自定义配置
#设置交换器名称   
spring.rabbitmq.exchange.name=fanoutExchange

创建Controller，通过浏览器请求，发送消息到RabbitMQ

@Controller
public class RabbitMQController {
	
	@Autowired
	private AmqpTemplate amqpTemplate;
	
	@Value("${spring.rabbitmq.exchange.name}")
	String exchange;
	
	
	@RequestMapping(value="/fanoutExchangeTest",method=RequestMethod.GET)
	@ResponseBody
	public void fanoutExchangeTest() throws InterruptedException {
		while (true) {
			Thread.sleep(1000);
			amqpTemplate.convertAndSend(exchange, "", "fanoutExchange....");
		}
	}
	
}

创建消息消费者module：编写队列消息处理组件，配置队列名称，交换器名称和类型，并进行绑定。

application.properties配置RabbitMQ信息

#RabbitMQ基本信息
spring.rabbitmq.host=182.61.40.184
spring.rabbitmq.port=5672
spring.rabbitmq.username=rabbitmq
spring.rabbitmq.password=rabbitmq

#自定义信息
#设置交换器名称
spring.rabbitmq.exchageName=fanoutExchange
#设置队列A名称
spring.rabbitmq.queueA=fanoutQueueA
#设置队列B名称
spring.rabbitmq.queueB=fanoutQueueB

队列A处理消息组件

@Component
@RabbitListener(
	bindings = @QueueBinding(
		value = @Queue(value = "${spring.rabbitmq.queueA}",autoDelete = "true"),
		exchange = @Exchange(value="${spring.rabbitmq.exchageName}",type = ExchangeTypes.FANOUT)
	)
)
public class RabbitMQComponentA {
	
	@RabbitHandler
	public void getMessage(String msg) {
		System.out.println("队列fanoutQueueA收到消息：" + msg + ".........");
	}
	
}

队列B处理消息组件

@Component
@RabbitListener(
	bindings = @QueueBinding(
		value = @Queue(value = "${spring.rabbitmq.queueB}",autoDelete = "true"),
		exchange = @Exchange(value="${spring.rabbitmq.exchageName}",type = ExchangeTypes.FANOUT)
	)
)
public class RabbitMQComponentB {
	
	@RabbitHandler
	public void getMessage(String msg) {
		System.out.println("队列fanoutQueueB收到消息：" + msg + ".........");
	}
	
}

测试：

启动两个module，访问Controller。
