我用springmvc整合nacos远程配置中心，以及nacos做dubbo的注册中心

你用的dubbo哪个版本，如果是2.7以后，那么不要引用外部的nacos registry ，因为2.7以后nacos registry就在dubbo本身的依赖下面

第一次用nacos整合spring,总是奇奇怪怪的问题，用过springcloud整合nacos,倒是没问题，本来说SSM整合nacos,替代disconf和zk,放弃了，不搞了

2.6.5

你好，经过昨天晚上12点半，以及今天一天的摸索，并不是依赖冲突，而是版本的兼容性问题。很多服务还是用SSM框架，建议spring版本dubbo版本，以及相关注册组件版本，对各个版本之间的兼容性做一个统一推荐配置，谢谢

辛苦熬夜了，但是Nacos这边属于被依赖，可以到Dubbo侧或者Spring侧提相应的问题

用把我的代码给你吗？郁闷了

这个是Dubbo的类冲突了，建议你排查下Dubbo的依赖

提供一下代码吧，纠结了

建议你还是自己排查一下依赖，这个是Java开发过程中很必备的技能

你好，经过昨天晚上12点半，以及今天一天的摸索，并不是依赖冲突，而是版本的兼容性问题。很多服务还是用SSM框架，建议spring版本dubbo版本，以及相关注册组件版本，对各个版本之间的兼容性做一个统一推荐配置，谢谢

你好，可以给一下您的各个组件的版本吗，遇到了【Caused by: java.lang.NoClassDefFoundError: com/alibaba/nacos/client/naming/utils/StringUtils】的问题

这个问题升级到Dubbo最新版本即可，这个问题可以提交到Dubbo。
