config-server的bootstrap.yml的配置如下：

server:
  port: 9010
spring:
  application:
    name: config
  cloud:
    config:
      server:
        git:
		  #碼雲的使用者名稱和密碼及地址

3、SpringCloud Config Client端配置

config-client pom.xml配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

複製程式碼

config-client的bootstrap.yml配置:

spring:
  application:
    name: user
  cloud:
    config:
      discovery:
        service-id: config
        enabled: true
      profile: pro

eureka:
  client:
    service-url:
      defaultZone: http://localhost:9001/eureka/

server:
  port: 9005
ribbon:
  eureka:
    enabled: true

複製程式碼

4、測試

啟動註冊中心eureka

啟動config server 訪問localhost:9010/user-dev.yml監測是否啟動成功

啟動config client

在client專案中寫一個測試類如下

測試類如下

@Component
@RefreshScope
@Data
@ConfigurationProperties(prefix = "spring.redis")
public class RedisConfig {
    private String host;
    private String port;
}

@RestController
@RequestMapping("/test")
public class ConfigController {

    @Autowired
    private RedisConfig redisConfig;

    @RequestMapping("/print")
    public String print() {
        return "host:" +"\t" + redisConfig.getHost()+"====Port:"+redisConfig.getPort();
    }
}

複製程式碼

頁面訪問http://localhost:9005/test/print,檢視結果

修改gitee中的user-dev.yml檔案

使用postman的post請求訪問http://localhost:9010/actuator/bus-refresh

繼續瀏覽器訪問http://localhost:9005/test/print檢視結果是否更新

自此config的重新整理基本完成，最後一步在gitee中配置webhooks，每一次push修改之後都會自動的通知到各個客戶端

4、配置倉庫中的webhooks

點選gitee中的管理——》webhooks，填入外網訪問的路徑即可。
