import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
/**
 *fanout类型的exchange会把消息推到所有跟fanoutExchange绑定的queue中，所以不需要指定routingkey，指定了也没用！
 */
@Configuration
public class FanoutRabbitConfig {
    @Bean
    public Queue AMessage() {
        return new Queue("fanout.A");
    }
    @Bean

    }
    @Bean
    FanoutExchange fanoutExchange2() {
        return new FanoutExchange("fanoutExchange2");
    }
    @Bean
    Binding bindingExchangeA(Queue AMessage,FanoutExchange fanoutExchange) {
        return BindingBuilder.bind(AMessage).to(fanoutExchange);
    }
