🙈SpringBoot使用扇型(广播)交换机(Fanout Exchange)

消费者

不需要routing key

扇型交换机在接收到消息后，会直接转发到绑定到它上面的所有队列。

@Component
public class FanoutConsumer {
    private static  final  String ENAME = "211-FanoutExchage-01";
    private static  final  String QNAME1 = "211-FanoutQueue-11";
    private static  final  String QNAME2 = "211-FanoutQueue-12";
    //定义一个交换机
    @Bean
    public FanoutExchange fanoutExchange(){
        return new FanoutExchange(ENAME, true, false);
    }
    //定义一个队列
    @Bean
    public Queue fanoutQueue1(){
        return QueueBuilder.durable(QNAME1).build();
    }
    //定义一个队列
    @Bean
    public Queue fanoutQueue2(){
        return QueueBuilder.durable(QNAME2).build();
    }
    //创建队列和交换机的绑定关系
    @Bean
    public Binding binding1(){
        return BindingBuilder.bind(fanoutQueue1()).to(fanoutExchange());
    }
    //创建队列和交换机的绑定关系
    @Bean
    public Binding binding2(){
        return BindingBuilder.bind(fanoutQueue2()).to(fanoutExchange());
    }
 
    @RabbitHandler
    @RabbitListener(queues =QNAME1)
    public void process1(UserRegisterOk userRegisterOk){
        System.out.println("消费者1收到:"+userRegisterOk.getName()+","+userRegisterOk.getPhone());
    }
    @RabbitHandler
    @RabbitListener(queues =QNAME2)
    public void process2(UserRegisterOk userRegisterOk){
        System.out.println("消费者2收到:"+userRegisterOk.getName()+","+userRegisterOk.getPhone());
    }
}

生产者

@Component
public class FanoutProducer {
 
    @Autowired
    private RabbitTemplate rabbitTemplate;
 
    public void sendMessage(){
        UserRegisterOk userRegisterOk = UserRegisterOk.builder().name("张三").phone("123456").build();
        //要将对象序列化,转成字符串,使用消息转换器MessageConverter
        rabbitTemplate.convertAndSend("211-FanoutExchage-01","",userRegisterOk);
        System.out.println("生产者生产-->张三注册成功");
    }
 
}

启动类

@SpringBootApplication
public class App1 {
 
    public static void main(String[] args) {
        ConfigurableApplicationContext context = SpringApplication.run(App1.class, args);
        FanoutProducer producer = context.getBean(FanoutProducer.class);
        producer.sendMessage();
    }
 
}

🙉SpringBoot使用主题交换机(Topic Exchange )

消费者

路由键和绑定键之间是有规则的

• * 代表两点之间一个占位单词
• # 代表后面所有，匹配所有

@Component
public class TopicConsumer {
    private static  final  String ENAME = "211-TopicExchage-01";
    private static  final  String QNAME1 = "211-TopicQueue-刘亦菲";
    private static  final  String QNAME2 = "211-TopicQueue-关晓彤";
    private static  final  String QNAME3 = "211-TopicQueue-邓紫棋";
    //定义一个交换机
    @Bean
    public TopicExchange topicExchange(){
        return new TopicExchange(ENAME, true, false);
    }
    //定义一个队列
    @Bean
    public Queue topicQueue1(){
        return QueueBuilder.durable(QNAME1).build();
    }
    //定义一个队列
    @Bean
    public Queue topicQueue2(){
        return QueueBuilder.durable(QNAME2).build();
    }
    //定义一个队列
    @Bean
    public Queue topicQueue3(){
        return QueueBuilder.durable(QNAME3).build();
    }
    //创建队列和交换机的绑定关系
    @Bean
    public Binding binding1(){
        return BindingBuilder.bind(topicQueue1()).to(topicExchange()).with("1.9.*");
    }
    //创建队列和交换机的绑定关系
    @Bean
    public Binding binding2(){
        return BindingBuilder.bind(topicQueue2()).to(topicExchange()).with("1.8.*");
    }
    //创建队列和交换机的绑定关系
    @Bean
    public Binding binding3(){
        return BindingBuilder.bind(topicQueue3()).to(topicExchange()).with("1.#");
    }
    //三个消费者
    @RabbitHandler
    @RabbitListener(queues =QNAME1)
    public void process1(UserRegisterOk userRegisterOk){
        System.out.println("刘亦菲收到:"+userRegisterOk.getName()+","+userRegisterOk.getHeight());
    }
    @RabbitHandler
    @RabbitListener(queues =QNAME2)
    public void process2(UserRegisterOk userRegisterOk){
        System.out.println("关晓彤收到:"+userRegisterOk.getName()+","+userRegisterOk.getHeight());
    }
    @RabbitHandler
    @RabbitListener(queues =QNAME3)
    public void process3(UserRegisterOk userRegisterOk){
        System.out.println("邓紫棋收到:"+userRegisterOk.getName()+","+userRegisterOk.getHeight());
    }
}

生产者

@Component
public class TopicProducer {
 
    @Autowired
    private RabbitTemplate rabbitTemplate;
 
    public void sendMessage(){
        UserRegisterOk userRegisterOk = UserRegisterOk.builder().name("moming").phone("123456").height("1.8.5").build();
        //要将对象序列化,转成字符串,使用消息转换器MessageConverter
        rabbitTemplate.convertAndSend("211-TopicExchage-01",userRegisterOk.getHeight(),userRegisterOk);
        System.out.println("生产者生产-->moming");
    }
 
}

启动类 

@SpringBootApplication
public class App2 {
 
    public static void main(String[] args) {
        ConfigurableApplicationContext context = SpringApplication.run(App2.class, args);
        TopicProducer producer = context.getBean(TopicProducer.class);
        producer.sendMessage();
    }
 
}
