创建Good Service子模块

xml如下， spring-cloud-netflix-learn-common是项目的通用模块，一般 model entity ，fegin client， DTO等都放在这个模块中

创建Controller返回Goods列表

package com.tubabaxuebiancheng.controller;

import com.tubabaxuebiancheng.entity.Good;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.ArrayList;
import java.util.List;

@RestController
public class GoodController {


    @Value("${server.port}")
    private String serverPort;
    @GetMapping("/goods")
    public List getGoods() {
        ArrayList<Good> goods = new ArrayList<>();
        goods.add(new Good(1, "商品1"+serverPort));
        goods.add(new Good(2, "商品2"+serverPort));
        goods.add(new Good(3, "商品1"+serverPort));
        return goods;
    }
}

配置properties

server.port=7101

#注册中心（Eureka Server）地址
eureka.client.service-url.defaultZone=http://localhost:7001/eureka/

#每2秒发送心跳告知注册中心服务还存活
eureka.instance.lease-renewal-interval-in-seconds=2

#告知注册中心如果10秒没有收到心跳就剔除服务
eureka.instance.lease-expiration-duration-in-seconds=10

# 客户端在注册时使用自己的IP而不是主机名，缺省：false
eureka.instance.prefer-ip-address=true

#服务实例id 必须保证唯一性，本例子中相同service用端口区分唯一性
eureka.instance.instance-id=netflix-learn-good-application-${server.port}


spring.application.name=good-application


management.endpoints.web.exposure.include=*

在主启动类上通过@EnableEurekaClient开启Eureka Client

package com.tubabaxuebiancheng;

import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

@SpringBootApplication
@EnableEurekaClient
public class GoodApplication {

    public static void main(String[] args) {
        org.springframework.boot.SpringApplication.run(GoodApplication.class, args);
    }
}

启动Good Service

Good Service已经注册到Eureka Server上
