排查思路:

  1. 檢查yml文件格式內容是否有誤(請注意:是遠程yml配置文件)

  1. 確認服務端的路徑正確(服務端3344)
server:
  port: 3344
spring:
  application:
    name: cloud-config-center # 服務名稱
  cloud:
    config:
      server:
        git:
#          uri: [email protected]:NoMessages/sprincloud-config.git # 填寫你自己的github路徑
          uri: https://github.com/NoMessages/sprincloud-config.git # 填寫你自己的github路徑
         # 搜索目錄
          search-paths:
            - springcloud-config
        # 閱讀分支
      label: master
# 註冊到eureka
eureka:
  client:
    service-url:
      defaultZone:  http://localhost:7001/eureka


  1. 確保服務端的yml配置文件無誤(bootstrap.yml)
server:
  port: 3355

spring:
  application:
    name: config-client
  cloud:
    config:
      label: master # master分支
      name: config  # 讀取config配置文件 前綴
      profile: dev  # 後綴爲dev
      uri: http://localhost:3344  # 相當於是從服務端獲取數據而不是github
eureka:
  client:
    service-url:
      defaultZone: http://eureka7001.com:7001/eureka


  1. 檢查配置是否對應遠程yml配置文件內容(3355客戶端)
@RestController
public class ConfigClientController {

    @Value("${info}")  <----- 這個對應的是遠程倉庫的info 請注意
    private String configInfo;

    @GetMapping("/configInfo")
    public String getConfigInfo(){
        return configInfo;
    }
}
