本文记录了一次在SpringBoot + Dubbo + Cat环境下，服务注册到Zookeeper时遇到的问题及解决方案。错误原因为项目中包含不同版本的Netty导致，最终通过统一Netty版本解决了问题。
项目是 springboot+dubbo+cat 的
一开始本地运行都ok，之后上qa测试环境直接tomcat启动报错了
先直接贴错：

一开始开以为是cat的错，找了好久好久都没解决，
之后让一位大神帮忙看了看，大神一上来就瞄准了netty，之后通过排包解决了问题。
错误原因：
项目及引用的jar包中包含的netty的版本不一致
最后只留了一个项目常用版本的netty，其他的都排除了
