解決方案

經過排查，SpringBoot的版本要小于 2.4，即將SpringBoot版本改成 2.3.4.RELEASE 可以正常啟動。

正常的配置文件：

<project><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.3.4.RELEASE</version><relativePath/></parent>...<dependencies><!-- nacos --><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId><version>2.2.1.RELEASE</version></dependency><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId><version>2.2.1.RELEASE</version></dependency></dependencies> </project>
