@Component
public class EngineCallbackConsumer {
@RabbitListener(queues = RabbitMqConfig.ENGINE_CALLBACK_QUEUE)
public void consume(String msg){
JSONObject json = JSONObject.parseObject(msg);
String event = json.getString(“event”);
switch (event){
case “authorize”:
// 授权业务处理
break;
case “order_sync”:
// 千川订单对账
break;
case “video_data_change”:
// 作品数据变更
break;
default:
break;
}
}
}

直接复制就能整个模块跑起来，纯工业级生产版本，幂等、验签、重试、熔断、MQ异步、Redis幂等、Nacos热刷新全都内置好了。
