说明

我导入了
<!--服务配置中心-->
 <dependency>
     <groupId>com.alibaba.cloud</groupId>
     <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
 </dependency>
我也已经写了bootstrap.properties文件,里面写了
 spring.application.name=nacos-config-example
 spring.cloud.nacos.config.server-addr=127.0.0.1:8848

解决

后来我按照网上加入了下面这个依赖就可以了,还不知道原因
刚开始加入这个依赖是不行的,现在又可以了,以后有机会得认真查看一下

 <!-- 若bootstrap配置不生效，加入以下依赖 -->
 <dependency>
     <groupId>org.springframework.cloud</groupId>
     <artifactId>spring-cloud-starter-bootstrap</artifactId>
     <version>3.0.0</version>
 </dependency>
