SpringCloud项目使用nacos配置

SpringCloud项目

pom.xml

注意SpringCloud和SpringCloudAlibaba的版本对应。

Spring Cloud Alibaba Version	Spring Cloud Version	Spring Boot Version

application.yaml

server-addr: nacos-local:8848 这里nacos-local我的电脑修改了hosts文件，指向了本机127.0.0.1地址

spring:
  application:
    name: depart-provider
  profiles:
    active: dev
  config:
    import:
     - optional:nacos:${spring.application.name}-${spring.profiles.active}.${spring.cloud.nacos.config.file-extension}
  cloud:
    nacos:

      config:
        file-extension: yaml
        username: nacos
        password: nacos

nacos添加配置

depart-provider-dev.yaml

  port: 8081
spring:

    username: root
    password: 123456
    driver-class-name: com.mysql.cj.jdbc.Driver

  application:
    name: depart-provider # 微服务名称
  config:
    import:
      - optional:nacos:${spring.application.name}.${spring.cloud.nacos.config.file-extension}
  cloud:
    nacos:
      config:
        file-extension: yaml

      logic-delete-field: deleted #逻辑删除的字段
      logic-delete-value: 1 # 已经逻辑删除的记录该字段值
      logic-not-delete-value: 0 # 未被逻辑删除的记录该字段值

    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
    # 枚举字段加上了@EnumValue注解后默认使用的是MybatisEnumTypeHandler，否则默认为mybatis EnumTypeHandler
    default-enum-type-handler: com.baomidou.mybatisplus.core.handlers.MybatisEnumTypeHandler
  # Mapper 所对应的 XML 文件位置，默认为“classpath*:/mapper/**/*.xml”
  mapper-locations:
    - classpath*:/mapper/**/*.xml

启动SpringCloud项目即可使用nacos中的配置文件。

nacos不同版本配置可能不能，谨慎对待！！！
