2 啟動類

@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文件夾下新建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     //這個暫時沒調試通，先通過uri的方式吧
#spring.cloud.config.discovery.service-id=CONFIG-SERVER
#spring.cloud.config.label=master

配置倉庫中的application.properties為所有服務的公共配置，

config lient 首先會查找application下的配置然後在找項目下的配置，如果application和項目下都有相同的配置，則項目配置會覆蓋application下的配置

4 編寫測試類

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

5 啟動項目訪問

test-dev 和 application-dev

成功！

spring cloud (八) Config client 和項目公共配置
