一：建立SpringBoot專案

選擇屬性時選擇client

修改DiscSystem4Application類  新增@EnableEurekaClient和@RestController

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
@EnableEurekaClient // 配置客戶端
@RestController // 配置為controller
public class DiscSystem4Application {

	public static void main(String[] args) {
		SpringApplication.run(DiscSystem4Application.class, args);
	}
	
	@Value("${server.port}") // 讀取配置檔案的埠
	String port;
	
	/**
	 * 設定一個方法
	 * 引數什麼的 可以用HttpServletRequest  也可以用 @RequestParam
	 * 測試我就不添加了
	 * @return
	 */
	@RequestMapping(value="/test")
	public String testMethod() { 
		return "Hello World!!! 埠為:" + port;
	}
}
 

新增application.yml檔案

server:
  port: 123456  # 你的埠
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:12345/eureka/  # 服務中心地址
spring:
  application:
    name: clientName # 客戶端的名字

pom檔案

注： 啟動上一篇文章中的server和本篇文章的client

訪問(http://localhost:12345/)
