**2.application.yml**

server:
      port: 8760
    
    spring:
      application:
        name: eureka-service
    
    eureka:
      client:
        serviceUrl:
          defaultZone: http://localhost:8761/eureka/

**3.ServerController（这里充当后面项目的“服务端”，返回对应的字符串结果）**

package com.cxb.springcloud.web;
    
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestParam;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    public class ServerController {
    
        @Value("${server.port}")
        String port;
    
        @RequestMapping("/hi")
        public String home(@RequestParam(value = "name", defaultValue = "frank") String name) {
            return "hi " + name + " ,i am from port:" + port;
        }
    }

**4.EurekaClientApplication启动类**

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

启动服务即可去服务中心查看。[http://localhost:8761/][http_localhost_8761]
