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

以你之姓@ 2023-07-10 05:05 21阅读 0赞

**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**

**         pom.xml导入RabbitMQ坐标**

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-amqp</artifactId>
    </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。**

**pom.xml导入RabbitMQ坐标**

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-amqp</artifactId>
    </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**。
