消息模型之Sample

开发生产者

@Autowired
private RabbitTemplate rabbitTemplate;

@Test
public void testHello(){
  rabbitTemplate.convertAndSend("hello","hello world");
}

开发消费者

@Component
@RabbitListener(queuesToDeclare = @Queue("hello"))
public class HelloCustomer {

    @RabbitHandler
    public void receive1(String message){
        System.out.println("message = " + message);
    }
}

消息模型之Work Queues

开发生产者

@Autowired
private RabbitTemplate rabbitTemplate;

@Test
public void testWork(){
  for (int i = 0; i < 10; i++) {
    rabbitTemplate.convertAndSend("work","hello work!");
  }
}

开发消费者

@Component
public class WorkCustomer {
    @RabbitListener(queuesToDeclare = @Queue("work"))
    public void receive1(String message){
        System.out.println("work message1 = " + message);
    }

    @RabbitListener(queuesToDeclare = @Queue("work"))
    public void receive2(String message){
        System.out.println("work message2 = " + message);
    }
}

消息模型之Publish-Subscribe

开发生产者

@Autowired
private RabbitTemplate rabbitTemplate;

@Test
public void testFanout() throws InterruptedException {
  rabbitTemplate.convertAndSend("logs","","这是日志广播");
}

开发消费者

@Component
public class FanoutCustomer {

    @RabbitListener(bindings = @QueueBinding(
            value = @Queue,
            exchange = @Exchange(name="logs",type = "fanout")
    ))
    public void receive1(String message){
        System.out.println("message1 = " + message);
    }

    @RabbitListener(bindings = @QueueBinding(
            value = @Queue, //创建临时队列
            exchange = @Exchange(name="logs",type = "fanout")  //绑定交换机类型
    ))
    public void receive2(String message){
        System.out.println("message2 = " + message);
    }
}

消息模型之Routing-Direct

开发生产者

@Autowired
private RabbitTemplate rabbitTemplate;

@Test
public void testDirect(){
  rabbitTemplate.convertAndSend("directs","error","error 的日志信息");
}

开发消费者

@Component
public class DirectCustomer {

    @RabbitListener(bindings ={
            @QueueBinding(
                    value = @Queue(),
                    key={"info","error"},
                    exchange = @Exchange(type = "direct",name="directs")
            )})
    public void receive1(String message){
        System.out.println("message1 = " + message);
    }

    @RabbitListener(bindings ={
            @QueueBinding(
                    value = @Queue(),
                    key={"error"},
                    exchange = @Exchange(type = "direct",name="directs")
            )})
    public void receive2(String message){
        System.out.println("message2 = " + message);
    }
}

消息模型之Routing-Topic

开发生产者

@Autowired
private RabbitTemplate rabbitTemplate;

@Test
public void testTopic(){
  rabbitTemplate.convertAndSend("topics","user.save.findAll","user.save.findAll 的消息");
}

开发消费者

@Component
public class TopCustomer {
    @RabbitListener(bindings = {
            @QueueBinding(
                    value = @Queue,
                    key = {"user.*"},
                    exchange = @Exchange(type = "topic",name = "topics")
            )
    })
    public void receive1(String message){
        System.out.println("message1 = " + message);
    }

    @RabbitListener(bindings = {
            @QueueBinding(
                    value = @Queue,
                    key = {"user.#"},
                    exchange = @Exchange(type = "topic",name = "topics")
            )
    })
    public void receive2(String message){
        System.out.println("message2 = " + message);
    }
}
