场景：
一个服务，注册中心使用nacos
服务启动时报错：

application.yml 中配置的nacos地址是192.168.5.12 ，但是启动时却是调用的 localhost:8848
仔细看报错信息 spring-cloud-starter-alibaba-nacos-config 怎么调用了nacos配置中心，可是这个服务没有用bootstrap.yml的配置
发现是pom中引入了配置中心的依赖
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency>
删除pom.xml中的nacos配置中心的依赖，则报错消失
