创建项目service-member

application.yml配置

eureka:

client:

serviceUrl:

defaultZone: http://localhost:8888/eureka/

server:

port: 8762

spring:

application:

name: service-member

服务接口

@RestController

public class MemberController {

@RequestMapping("/getUserList")

public List<String> getUserList() {

List<String> listUser = new ArrayList<String>();

listUser.add("zhangsan");

listUser.add("lisi");

listUser.add("yushengjun");

return listUser;

}

}

发布服务

通过注解@EnableEurekaClient 表明自己是一个eurekaclient.

@SpringBootApplication

@EnableEurekaClient

public class AppMember {

public static void main(String[] args) {

SpringApplication.run(AppMember.class, args);

}

}

演示效果

需要指明spring.application.name,这个很重要，这在以后的服务与服务之间相互调用一般都是根据这个name 。 
启动工程，打开127.0.0.1:8888 ，即eureka server 的网址：

你会发现一个服务已经注册在服务中了，服务名为SERVICE-HI ,端口为7862

这时打开 http://127.0.0.1:8762/getUserList ，你会在浏览器上看到 :

["zhangsan","lisi","yushengjun"]
