could not find any agent worker with com.xxx.xxx

[creasy2010]

在开发过程中 调用 com.qianmi.mc.api.buyer.BuyerActivityQueryProvider 出现异常.跟踪如下:

dubbo 启动时,providerurl信息,可以看出BuyerActivityQueryProvider 并没有相应的provider

登陆 zookeeper 查看 ,确实没有

查看 dubbo源代码 . 在调用接口,如果没找到相应的SocketWorker,则会报:Could not find any agent worker

  private _handleDubboInvoke(requestId: number) {
    //get request context
    const ctx = queue.requestQueue.get(requestId);
    //get socket agent list
    const agentAddrList = this._zkClient.getAgentAddrList(ctx);
    log('agentAddrSet-> %O', agentAddrList);
    const worker = this._serverAgent.getAvailableSocketWorker(agentAddrList);

    //if could not find any available socket agent worker
    if (!worker) {
      const {requestId, dubboInterface, version, group} = ctx;
      const msg = `requestId#${requestId}:Could not find any agent worker with ${dubboInterface}#${version}#${group} agentList: ${agentAddrList.join(
        ',',
      )}`;
      const err = new ScheduleError(msg);
      this._handleFailed(requestId, err);
      log(err);
      traceErr(err);
      return;
    }

    ctx.invokeHost = worker.host;
    ctx.invokePort = worker.port;

    const providerProps = this._zkClient.getDubboServiceProp(ctx);
    queue.consume(ctx.requestId, worker, providerProps);
  }

1. 可能真的是zk中就没有这个注册的dubbo service url
2. 可能是zk发生了disconnected, 导致负载重启之后，不会再连上，因为zk不会watch没有反应能力了
