## 简介 ##

**说明**

本文介绍SpringCloud整合Nacos使用@RefreshScope实现动态更新配置。

**官网**

[Nacos Spring Cloud 快速开始][Nacos Spring Cloud]

**动态更新的介绍**

动态更新的含义：修改应用的配置之后，无需重启应用，就能使用新的配置。

**本文的版本**

*  spring-boot-starter-parent:2.4.13
 *  spring-cloud-dependencies:2020.0.1
 *  spring-cloud-alibaba-dependencies:2021.1
 *  nacos服务端：1.4.3

## 效果展示 ##

**1.启动Nacos服务端**

本处我使用Windows启动Nacos单机：startup.cmd -m standalone

**2.Nacos服务端新增命名空间**
