2, 建立config服务工程

@EnableConfigServer
@SpringBootApplication
public class ConfigServiceApplication {
    
    public static void main(String[] args) {
        SpringApplication.run(ConfigServiceApplication.class, args);
    }
}

server.port=8888

# 配置git仓库地址
spring.cloud.config.server.git.uri=http://Gitlab.xxx.com/xx/xx_configuration.git
spring.cloud.config.server.git.username=xxx
spring.cloud.config.server.git.password=xxxx
#Git分支
spring.cloud.config.label=master
#spring.cloud.config.server.git.search-paths=src/main/resources/config

3, 配置Client工程

@SpringBootApplication
public class ConfigClientApplication {

    public static void main(String[] args) {
        SpringApplication.run(ConfigClientApplication.class, args);
    }
}

@RefreshScope
@RestController
class MessageRestController {

    @Value("${message1:Hello default}")
    private String message;

    @RequestMapping("/message")
    String getMessage() {
        return this.message;
    }
}

server.port=8889
#对应仓库中yml
spring.application.name=client1

management.endpoints.web.exposure.include=*

spring.cloud.config.profile=dev 
spring.cloud.config.label=master
spring.cloud.config.uri=http://localhost:8888

3，验证

先启动Service工程，访问 http://localhost:8888/client1/dev/master，如果能看到配置的属性说明服务启动成功。

再启动Client工程，访问：http://localhost:8889/message

Config Server启动以后，我们可以通过它暴露的端点获取配置文件内容，http请求地址与配置文件映射关系如下：
# 映射{application}-{profile}.properties文件
/{application}/{profile}/[{label}]
/{label}/{application}-{profile}.properties
/{application}-{profile}.properties
/{label}/{application}-{profile}.yml
/{application}-{profile}.yml
{application}通常使用微服务名称，对应Git仓库中文件名的前缀；
{profile}对应{application}-后面的dev、pro、test等；
{label}对应Git仓库的分支名，默认为master。

4，自动刷新

修改client-dev.yml的属性，然后再用postman以post方式请求http://localhost:8889/actuator/refresh。

再次访问http://localhost:8889/message, 可以看到内容变化。
