## 现象 ##

按照官方文档 https://nacos.io/zh-cn/docs/quick-start-spring-cloud.html 进行配置后，抛异常报错，无法获取配置。

所有依赖配置如下：

    </project>

bootstrap.properties

spring.cloud.nacos.config.server-addr=192.168.1.222
    spring.application.name=nacos-demo

## 解决 ##

添加如下依赖，然后就解决了

<dependency>
         <groupId>org.springframework.cloud</groupId>
         <artifactId>spring-cloud-starter-bootstrap</artifactId>
         <version>3.0.3</version>
     </dependency>

## 吐槽 ##

1、官方文档未提及  
2、官方给的 example 代码很老
