springboot整合dubbo的问题之一。zookeeper客户端和zookeeper版本不匹配问题_dubbo 和 zokeeper 中的netty版本不一致-优快云博客

本文主要讲述了在SpringBoot项目中整合Dubbo时遇到的Zookeeper客户端与服务器版本不兼容的问题。错误提示表明，Zookeeper服务器版本为3.4.6，而客户端版本可能不匹配。解决方案是使用与服务器相匹配的Zookeeper客户端版本，例如2.x版本。此外，作者建议避免使用快速创建的SpringBoot工程，而应选择创建Maven工程，并手动引入SpringBoot和Dubbo的依赖。项目源码已上传至GitHub，供参考。
