純註解方式

@Component
public class Listener {

    @RabbitListener(bindings = @QueueBinding(
            value = @Queue(value = "EmailQueue"),
            exchange = @Exchange(
                    value = "EmailExchange",
                    ignoreDeclarationExceptions = "true",
                    type = ExchangeTypes.DIRECT
            ),
            key = {"EmailRoutingKey"}))
    public void listen(String msg){
        System.out.println("接收到消息：" + msg);
