3. 完成上述两步后，应用会从 Nacos Config 中获取相应的配置，并添加在 Spring Environment 的 PropertySources 中。这里我们使用 @Value 注解来将对应的配置注入到 SampleController 的 userName 和 age 字段，并添加 @RefreshScope 打开动态刷新功能

1. 增加配置，在应用的 /src/main/resources/application.properties 中添加基本配置信息
spring.application.name=nacos-config-example
server.port=18084
server.port=18084
management.endpoints.web.exposure.include=*
2. 启动应用，支持 IDE 直接启动和编译打包后启动。

3. After completing the above two steps, the application will get the externalized configuration from Nacos Server and put it in the Spring Environment's PropertySources.We use the @Value annotation to inject the corresponding configuration into the userName and age fields of the SampleController, and add @RefreshScope to turn on dynamic refresh .
