SpringBoot整合rabbitMQ,启动服务便创建交换机和队列

1.启动服务不默认先创建队列的话,在启动消费者时候,消费者服务监听会找不到对应的队列而报错,启动失败

@Component
public class OrderRabbitMQConfig {

    @Autowired
    RabbitAdmin rabbitAdmin;

    /**
     * 派单队列
     */
    public static final String ORDER_DIC_QUEUE = "order_dic_queue";
    /**
     * 补单对接
     */
    public static final String ORDER_CREATE_QUEUE = "order_create_queue";
    /**
     * 订单交换机
     */
    private static final String ORDER_EXCHANGE_NAME = "order_exchange_name";

    /**
     * 定义派单队列
     */
    @Bean
    public Queue directOrderDicQueue() {
        return new Queue(ORDER_DIC_QUEUE);
    }

    /**
     * 定义补派单队列
     */
    @Bean
    public Queue directCreateOrderQueue() {
        return new Queue(ORDER_CREATE_QUEUE);
    }

    /**
     * 定义订单交换机
     */
    @Bean
    DirectExchange directOrderExchange() {
        return new DirectExchange(ORDER_EXCHANGE_NAME);
    }

    /**
     * 派单队列与交换机绑定
     */
    @Bean
    Binding bindingExchangeOrderDicQueue() {
        return BindingBuilder.bind(directOrderDicQueue()).to(directOrderExchange()).with("orderRoutingKey");
    }

    /**
     * 补单队列与交换机绑定
     */
    @Bean
    Binding bindingExchangeCreateOrder() {
        return BindingBuilder.bind(directCreateOrderQueue()).to(directOrderExchange()).with("orderRoutingKey");
    }

    //创建初始化RabbitAdmin对象
    @Bean
    public RabbitAdmin rabbitAdmin(ConnectionFactory connectionFactory) {
        RabbitAdmin rabbitAdmin = new RabbitAdmin(connectionFactory);
        // 只有设置为 true，spring 才会加载 RabbitAdmin 这个类
        rabbitAdmin.setAutoStartup(true);
        return rabbitAdmin;
    }
    //创建交换机和对列
    @Bean
    public void createExchangeQueue (){
        rabbitAdmin.declareExchange(directOrderExchange());
        rabbitAdmin.declareQueue(directOrderDicQueue());
        rabbitAdmin.declareQueue(directCreateOrderQueue());
    }
    
}
