Question

我能够启动Config Server，并且可以通过http://localhost:8888/customer-microservice/dev加载配置文件，如下所示

我正尝试通过spring客户端应用程序中存在的控制器进行测试，如下所示：

@SpringBootApplication
@EnableSwagger2
@EnableDiscoveryClient
public class CustomerMicroserviceApplication {

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

}

@RestController
@RefreshScope
public class GreetController {

    @Value("${name}")
    private String personName;

    @RequestMapping("/greeting")
    public String greet(){
        return "hello " + personName;
    }
}

bootstrap.yml中存在的配置如下：

启动客户端应用程序时，它失败并显示错误消息，原因如下：java.lang.IllegalArgumentException：无法解析值“ $ {name}”中的占位符“ name”

我认为客户端应用程序无法联系配置服务器。

我浏览了很多次以解决此问题，但是我无法理解该问题。敬请帮助，因为我刚接触Spring Cloud。

完成客户微服务的pom.xml如下：

Answer 1

bootstrap.yml文件应重命名为bootstrap.yaml或bootstrap.properties。使用的文件扩展名错误。
