zookeeper dubbo 配置错误总结

学者使用zookeeper 、dubbo 但是在配置文件以及客户端连接的时候出现了如下问题，下面来看看解决方法

1、spring配置文件dubbo标签报错

解决方法：选择windows-->preferrence-->xml->xmlcatalog-->add->catalog entry -->file system,选择模版文件后，修改key值为“http://code.alibabatech.com/schema/dubbo/dubbo.xsd”，然后在eclipse中文件报错处点击右键“validate”。

2、配置好后服务端能起来，但是客户获取服务端服务时一直报异常

异常信息如下：

解决办法： 这个异常出现的原因是zookeeper使用的版本不一致导致的，所以建议安装的zookeeper、客户端的zookeeper架包以及服务端的zookeeper架包使用相同版本的就ok！
