#自定义交换机 队列名称 和 键
custom:
  exchange-name: spirit_direct_exchange
  queue-name: task_direct_queue
  routing-key: handle_task

//读取配置文件
@NoArgsConstructor
@Component
public class QueueSignConfig {
    //自定义交换机
    public static String EXCHAGE_NAME;
    //自定义队列名
    public static String QUEUE_NAME;
    //自定义键
    public static String ROUTING_KEY;

    @Value("${custom.exchange-name}")
    public void setExchageName(String exchageName) {
        EXCHAGE_NAME = exchageName;
    }

    @Value("${custom.queue-name}")
    public void setQueueName(String queueName) {
        QUEUE_NAME = queueName;
    }

    @Value("${custom.routing-key}")
    public void setRoutingKey(String routingKey) {
        ROUTING_KEY = routingKey;
    }
}
