Dubbo启动错误

加完Nacos配置后报错

看起来是Slf4j缺失(注意这里是添加slf4j-nop)，尝试添加

<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>slf4j-nop</artifactId>
  <version>2.0.7</version>
</dependency>

加完之后尝试启动dubbo server

网上各种让导入 commons-long3.3.1 jar包的，连标点符号都一样，你们真的试过吗？？

最后我把nacos的版本调低了解决
<dependency>
  <groupId>com.alibaba.nacos</groupId>
  <artifactId>nacos-client</artifactId>
  <version>1.4.4</version>
</dependency>

 [2023-08-09 13:14:36] Dubbo service server started!

Nacos也注册成功
