3.Application

import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
    
    
    @SpringBootApplication
    @EnableEurekaClient
    public class ServiceAdminApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(ServiceAdminApplication.class, args);
        }
    }

4.application.yml

spring:
      application:
        name: hello-spring-cloud-service-admin
      
    server:
      port: 8763
    
    eureka:
      client:
        serviceUrl:
          defaultZone: http://localhost:8761/eureka/

6.提供服务  创建一个controller

@RestController
    public class AdminController {
    
        @Value("${server.port}")
        private String port;
    
        @GetMapping("hi")
        public String sayHi(String message) {
            return String.format("Hi your message is : %s port : %s", message, port);
        }
    }
