1.创建srpingBoot的工程

2.pom文件如下，如果出现无法正确读取nacos的配置，很大程度是因为jar包的版本问题导致，当前我使用的是

springBoot的版本：

<parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.7.18</version><relativePath/> <!-- lookup parent from repository -->
</parent>

nacos相关的版本

<dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId><version>2021.0.1.0</version>
</dependency>
<dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId><version>2021.0.1.0</version>
</dependency>

3.yaml文件配置：
