spring 配置服务器未加载本机属性
spring config server not loading native properties
我正在尝试让一个示例应用程序为我自己工作，因为我刚刚开始玩 Spring Boot.我已经创建了 restful 服务，下一步是获取配置服务器 运行，这样我就可以动态刷新属性。但是我的配置服务器似乎没有加载属性。所以我有以下设置：

hello-service /restful 服务，为了清楚起见，我尝试加载 属性 省略的代码
@RestController

return new Greeting(counter.incrementAndGet(),

还有我的application.properties
server.port=${PORT:9001}
spring.profiles.active=native
bootstrap.properties
spring.application.name=hello-service
spring.cloud.config.uri=http://localhost:8889
因此，当我点击 restful 端点问候语时，它会抛出如下异常

spring.application.name=hello-service 需要进入 bootstrap.properties（bootstrap 而不是 Bootstrap）。否则，configserver 不知道要获取哪个配置。
