	Action:

	Add a spring.config.import=nacos: property to your configuration.

		To disable this check, set spring.cloud.nacos.config.import-check.enabled=false.

2、解决方法

SpringCloud 2020.* 版本把 bootstrap 禁用了，导致在读取文件的时候读取不到而报错，将 bootstrap 重新导入进来就会生效了。
	
	<!-- 配置中心 -->
	<dependency>
		<groupId>com.alibaba.cloud</groupId>
		<artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
	</dependency>
	<!-- 引入bootstrap，否则报错（如上错误日志） -->
	<dependency>
		<groupId>org.springframework.cloud</groupId>
		<artifactId>spring-cloud-starter-bootstrap</artifactId>
		<version>3.1.1</version>
	</dependency>
