解决No spring.config.import property has been defined
在学习Nacos组件，加载多配置集时遇到问题，希望微服务在读取配置文件之前先去nacos中读取配置文件优先于本地配置。配置了bootstrap.properties
后启动项目报错：
Description:
No spring.config.import property has been defined
Action:
Add a spring.config.import=nacos: property to your configuration.
If configuration is not required add spring.config.import=optional:nacos: instead.
To disable this check, set spring.cloud.nacos.config.import-check.enabled=false.
Process finished with exit code 1
后续找解决方案发现是因为在springcloud 2020.0.2版本中把bootstrap的相关依赖从spring-cloud-starter-config中移除了，所以现在在2020.02 以后需要单独引入spring-cloud-starter-bootstrap 依赖。版本对应网站：https://mvnrepository.***/
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-bootstrap</artifactId>
<version>3.0.3</version>
</dependency>
刷新依赖以后正常运行，配置也读取到了。
