描述：未定义spring.config.import属性
操作建议：在配置中添加spring.config.import=configserver:属性。如果不需要配置，请改为添加spring.config.import=optional:configserver:。要禁用此检查，请设置spring.cloud.config.enabled=false或spring.cloud.config.import-check.enabled=false。

解决步骤 #

方案1：启用Spring Cloud Config（推荐） #

在application.yml的spring节点下添加spring.config.import=configserver:，已配置的spring.cloud.config.uri会被自动读取，无需在import中重复指定地址。同时修正jpa节点下的冗余配置：

server:
  port: 9192
spring:
  config:
    import: configserver:
  datasource:
    url: jdbc:h2:mem:mydb
    username: sa
    password: password
    driverClassName: org.h2.Driver
  jpa:
    database-platform: org.hibernate.dialect.H2Dialect
  h2:
    console:
      enabled: true
  application:
    name: ORDER-SERVICE
  cloud:
    config:
      uri:
        - http://localhost:9196

方案2：可选依赖Config Server #

如果Config Server并非启动必需项，可将配置改为：

spring:
  config:
    import: optional:configserver:

此配置下，若Config Server不可用，应用仍能正常启动。

方案3：禁用Spring Cloud Config #

若无需使用Config Server，可直接移除spring-cloud-starter-config依赖，或添加以下配置禁用检查：

spring:
  cloud:
    config:
      enabled: false
      # 或仅禁用检查
      import-check:
        enabled: false
