2 启动类

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

3 配置文件、

application.properties

server.port=7023
spring.application.name=test
eureka.client.service-url.defaultZone=http://localhost:8080/eureka/

在resources文件夹下新建bootstrap.properties文件

spring.cloud.config.uri=http://localhost:7066

spring.cloud.config.name=test
spring.cloud.config.profile=dev

#spring.cloud.config.discovery.enabled=true     //这个暂时没调试通，先通过uri的方式吧
#spring.cloud.config.discovery.service-id=CONFIG-SERVER
#spring.cloud.config.label=master

配置仓库中的application.properties为所有服务的公共配置，

config lient 首先会查找application下的配置然后在找项目下的配置，如果application和项目下都有相同的配置，则项目配置会覆盖application下的配置

4 编写测试类

@RestController
public class TestController {
    @Value("${version}")
    private String version;
 
    @Value("${all.data.url}")
    private String dataUrl;
 
    @GetMapping("/")
    public String getMessage() {
        return version+dataUrl;
    }
}

5 启动项目访问

test-dev  和 application-dev

成功！
