2、SpringCloud Config Server端配置

config-server pom.xml的配置如下

<?xml version="1.0" encoding="UTF-8"?>

config-server的bootstrap.yml的配置如下：

server:
      port: 9010
    spring:
      application:
        name: config
      cloud:
        config:
          server:
            git:
    		  #码云的用户名和密码及地址
              username: **** 
              password: ****
              uri: https://gitee.com/lijiaxi118/blog-repo
    eureka:
      client:
        service-url:
          defaultZone: http://localhost:9001/eureka/
    management:
      endpoints:
        web:
          exposure:
            include: "bus-refresh"

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"
    		 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    		<dependencies>
    			<dependency>

    			<url>https://repo.spring.io/milestone</url>
    		</repository>
    	</repositories>
    
    </project>

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

4、测试

启动注册中心eureka

启动config server 访问localhost:9010/user-dev.yml监测是否启动成功

启动config client

在client项目中写一个测试类如下

测试类如下

@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();
        }
    }

页面访问http://localhost:9005/test/print,查看结果

修改gitee中的user-dev.yml文件

使用postman的post请求访问http://localhost:9010/actuator/bus-refresh

继续浏览器访问http://localhost:9005/test/print查看结果是否更新

自此config的刷新基本完成，最后一步在gitee中配置webhooks，每一次push修改之后都会自动的通知到各个客户端

4、配置仓库中的webhooks

点击gitee中的管理——》webhooks，填入外网访问的路径即可。
