cloud-alibaba的nacos坑

 
            com.alibaba.cloud
            spring-cloud-starter-alibaba-nacos-config
            2.2.1.RELEASE
 

获取配置文件命名格式:

{nacos.config.prefix}.{nacos.config.file-extension}{nacos.config.prefix}-{spring.profiles.active}.{nacos.file-extension}

spring:
  application:
    name: gulimall-cart1
  profiles:
    active: dev
  cloud:
    nacos:
      discovery:
        server-addr: 39.99.234.10:8848
      config:
        server-addr: 39.99.234.10:8848
        file-extension: yaml
        prefix: gulimall-cart #推荐使用这个，因为name和他具有相同效果但语义不如prefix明确

最终获取配置文件名查看启动日志

请使用Value去进行获取
原因是应为：用的不是nacos原生，而是用的spring-cloud-starter-alibaba-nacos-config
官方说明：
After completing the above two steps, the application will get the externalized configuration from Nacos Server and put it in the Spring Environment’s PropertySources.We use the @Value annotation to inject the corresponding configuration into the userName and age fields of the SampleController, and add @RefreshScope to turn on dynamic refresh .
所以按照阿里官网的意思，正常就应该用@Value而不应该用@NacosValue
