在客户端应用程序中使用中央 Spring Cloud 配置服务器从 GitHub 存储库读取配置。但我无法读取这些值。我能够正确加载这两个应用程序，但无法访问属性。
当我使用服务器配置应用程序访问 GitHub 配置时，它工作正常，如下所示：
<http://localhost:8888/actuator/default>
{"name":"actuator","profiles":["default"],"label":"master","version":"234ebf3e6bee6446cb50d9188f82afe47dc151e8","state":null,"propertySources":[{"name":"https://github.com/Antony12931a0519/spring-config-server/application.properties","source":{"spring.config.server.message":"Hello Am from Github"}}]}
我在评估端点时出错：
<http://localhost:12342/msg>
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).
Error creating bean with name 'scopedTarget.controllerTest': Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'spring.config.server.message' in string value "${spring.config.server.message}"
云服务器代码：
@SpringBootApplication
@EnableConfigServer
public class ConfigServerApplication {
public static void main(String[] args) {
SpringApplication.run(ConfigServerApplication.class, args);
}
}
