基于注解声明队列和交换机

一,生产两个消费监听者(消费端)

 

 1 @RabbitListener(bindings = @QueueBinding(
 2 value = @Queue(name = "direct.queue1"),    //队列名称
 3 exchange = @Exchange(name = "itcast.direct", type = ExchangeTypes.DIRECT),  //交换机名称,类型
 4 key = {"red", "blue"} //路由名称
 5 ))
 6 public void listenDirectQueue1(String msg){
 7 System.out.println("消费者接收到direct.queue1的消息：【" + msg + "】");
 8 }
 9 
10 @RabbitListener(bindings = @QueueBinding(
11 value = @Queue(name = "direct.queue2"),
12 exchange = @Exchange(name = "itcast.direct", type = ExchangeTypes.DIRECT),
13 key = {"red", "yellow"}
14 ))
15 public void listenDirectQueue2(String msg){
16 System.out.println("消费者接收到direct.queue2的消息：【" + msg + "】");
17 }

 

消息发送,需要指名交换机名称,路由器名称,还有发送的内容(发送端)

1 @Test
2 public void testSendDirectExchange() {
3 // 交换机名称
4 String exchangeName = "itcast.direct";
5 // 消息
6 String message = "hello Mq！";
7 // 发送消息
8 rabbitTemplate.convertAndSend(exchangeName, "red", message);
9 }
