node与java通信 java端是dubbo

公司搞前后端分离后端原来是用java写的服务通信是用node dubbo，现在想用node做前后端分离， 网上找了很多node dubbo 的 var zookeeper = require(‘node-zookeeper-client’);

var client = zookeeper.createClient(‘192.168.16.244:2181’); var path = ‘/com.szy.hms.openservice.facade.IMySchoolFacade’;

function getData(client, path) { client.getData( path, function (event) { console.log(‘Got event: %s’, event); getData(client, path); }, function (error, data, stat) { if (error) { console.log(‘Error occurred when getting data: %s.’, error); return; }

  console.log(
    'Node: %s has data: %s, version: %d',
    path,
    data ? data.toString() : undefined,
    stat.version
  );
}

); }

client.once(‘connected’, function () { console.log(‘Connected to ZooKeeper.’); getData(client, path); });

client.connect();

最后都是 Connected to ZooKeeper. Node: /com.szy.hms.openservice.facade.IMySchoolFacade has data: undefined, version: 0
