第二篇：【Spring Cloud】 Eureka client 搭建消費者模塊

消費者模塊指的是【基礎數據項目】【用戶項目】【訂單項目】【支付項目】，能夠理解成spring cloud的一個客戶端，而eureka是一個服務端，client是服務端進行註冊服務。

eureka統一管理這些服務。

1.建立訂單項目

 

2.選擇組件

 

3.pom文件

主要是spring-cloud-starter-netflix-eureka-client，表示是一個spring cloud的一個客戶端，會想eureka註冊。

</project>

4.配置主類

package com.cohesion;

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

@SpringBootApplication
@EnableEurekaClient//表示本身是spring cloud的客戶端 會想eureka註冊
public class SpringCloudOrderApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringCloudOrderApplication.class, args);
    }
}

5.配置application.yml文件

server:
  port: 8081

spring:
  application:
    name: service-order

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8080/eureka/

 6.啓動Spring Cloud Client【訂單項目】 8081端口服務

7.啓動後查看註冊中心是否已經有這個服務

能夠看到服務已經註冊到註冊中心
