根据 SpringCloud Alibaba 的github的版本说明 H版本的Springcloud推荐使用Spring Cloud Alibaba Version 2.2.0.RELEASE
我把我的父POM文件的版本改为 2.2.0.RELEASE
<dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-alibaba-dependencies</artifactId> <version>2.2.0.RELEASE</version> <type>pom</type> <scope>import</scope> </dependency>
成功启动啦！
Nacos的管理界面：localhostL:8848/nacos 默认用户名密码都是 nacos
