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.配置文件
以上是一个服务启动时的日志，无法启动。配置文件中没配置spring.cloud.nacos.config，为什么仍然提示配置spring.config.import？
原因及解决方案
问题很清楚。mall-user/pom.xml 中依赖了 spring-cloud-starter-alibaba-nacos-config，Spring Cloud Alibaba 2021.0.5.0 会强制校验 spring.config.import 是否配置------跟 application.yml 里有没有 spring.cloud.nacos.config 块无关。
你有三种修复方式，选一种即可：
方案一：禁用强制检查（最简单）
spring:
cloud:
nacos:
config:
import-check:
enabled: false适用场景：只需要 discovery，不需要 config 中心。
方案二：补上 spring.config.import
spring:
config:
import:
- optional:nacos:mall-user.yaml?refreshEnabled=true适用场景：确实需要从 Nacos 加载配置。但要注意 Nacos 上 mall-user.yaml 的编码问题（之前报 MalformedInputException 就是因为 Nacos 上的文件编码不是合法 UTF-8）。
方案三：从 pom.xml 移除 config 依赖（最彻底）
把 mall-user/pom.xml 中的这一行删掉：
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
</dependency>适用场景：完全不需要 Nacos 配置中心，只用 discovery。
建议：先用方案一快速恢复启动，后续如果要用配置中心再切到方案二并修复 Nacos 上的文件编码。
