我使用的是快速入门的代码，consul测试过没有什么问题，但是zk却有问题，请大神帮忙解答一下

看一下classpath下是否有motan-registry-zookeeper包

[hexian55]

maven没有引motan-registry-zookeeper这个包导致的 感谢 另外还有一个问题帮忙解答一下
限制服务端连接池工作线程数 motan:protocol id="demoMotan" name="motan" maxWorkerThread="800" minWorkerThread="20" 我在service中，怎么设置这个protocol呢？还在只需要再server.xml里面加上这一行？

@hexian55 service的配置项里， export="protocol:port"

可以参考https://github.com/weibocom/motan/blob/master/motan-demo/motan-demo-server/src/main/resources/motan_demo_server.xml
