服务启动报错： [ main] c.a.n.c.config.http.ServerHttpAgent : no available server

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
