RabbitMQ-发布订阅模式和路由模式

接上文 RabbitMQ-工作队列

1 发布订阅模式

将之前的配置类内容都替换掉

  @Bean("fanoutExchange")
    public Exchange exchange(){
      	//注意这里是fanoutExchange
        return ExchangeBuilder.fanoutExchange("amq.fanout").build();
    }

    @Bean("yydsQueue1")
    public Queue queue(){
        return QueueBuilder.nonDurable("yyds1").build();
    }

    @Bean("binding")
    public Binding binding(@Qualifier("fanoutExchange") Exchange exchange,
                           @Qualifier("yydsQueue1") Queue queue){
        return BindingBuilder
                .bind(queue)
                .to(exchange)
                .with("yyds1")
                .noargs();
    }

    @Bean("yydsQueue2")
    public Queue queue2(){
        return QueueBuilder.nonDurable("yyds2").build();
    }

    @Bean("binding2")
    public Binding binding2(@Qualifier("fanoutExchange") Exchange exchange,
                           @Qualifier("yydsQueue2") Queue queue){
        return BindingBuilder
                .bind(queue)
                .to(exchange)
                .with("yyds2")
                .noargs();
    }

两个消息队列(yyds1,yyds2)都绑定到fanoutExchange上，这样给fanoutExchange转发消息就会给到yyds1，yyds2两个队列上

重写监听器

    @RabbitListener(queues = "yyds1")
    public void receiver(String data){
        System.out.println("一号消息队列监听器 "+data);
    }

    @RabbitListener(queues = "yyds2")
    public void receiver2(String data){
        System.out.println("二号消息队列监听器 "+data);
    }

启动服务，出现两个队列

进入交换机详情

2 路由模式

关闭服务，删除yyds1，yyds2，yyds三个队列

修改配置类

@Configuration
public class RabbitConfiguration {

    @Bean("directExchange")
    public Exchange exchange(){
        return ExchangeBuilder.directExchange("amq.direct").build();
    }

    @Bean("yydsQueue")
    public Queue queue(){
        return QueueBuilder.nonDurable("yyds").build();
    }

    @Bean("binding")   //使用yyds1绑定
    public Binding binding(@Qualifier("directExchange") Exchange exchange,
                           @Qualifier("yydsQueue") Queue queue){
        return BindingBuilder
                .bind(queue)
                .to(exchange)
                .with("yyds1")
                .noargs();
    }

    @Bean("binding2")   //使用yyds2绑定
    public Binding binding2(@Qualifier("directExchange") Exchange exchange,
                           @Qualifier("yydsQueue") Queue queue){
        return BindingBuilder
                .bind(queue)
                .to(exchange)
                .with("yyds2")
                .noargs();
    }
}
