Spring Cloud 集成 Nacos Config 时报 Fetching config from server at : http://localhost:8888

事件:

公司Spring Cloud项目原先用的注册中心是Eureka,现在准备换成Nacos,Nacos自身带Config Server,所以打算把Spring Cloud Config 也替换掉。

结果启动时警告信息如下:

2019-08-05 17:46:53.018  INFO 32425 --- [           main] b.c.PropertySourceBootstrapConfiguration : Located property source: CompositePropertySource {name='NACOS', propertySources=[NacosPropertySource {name='user-base-service-dev.yml'}, NacosPropertySource {name='user-base-service.yml'}]}

原因:

看到输出警告的类为:ConfigServicePropertySourceLocator,盲猜可能是Spring Cloud微服务项目在注解了@SpringCloudApplication以后,认为你用的是Spring Cloud Config自动去加载Spring Cloud Config默认的配置信息。但是你并没有配置spring.cloud.config.url属性,所有采用了默认地址:http://localhost:8888

解决:

更改 bootstrap.yml配置文件,添加 spring.cloud.config = false 。

原配置文件为:

spring:
  application:
    name: user-base-service
  profiles:
    active: dev

  cloud:
    nacos:
      config:
        server-addr: 192.168.1.35:8848
        file-extension: yml

更改后为:

spring:
  application:
    name: user-base-service
  profiles:
    active: dev

  cloud:
    config:
      enabled: false
    nacos:
      config:
        server-addr: 192.168.1.35:8848
        file-extension: yml

重新启动微服务,结果成功了。没有了ConfigServicePropertySourceLocator的警告信息。
