第二篇：【Spring Cloud】 Eureka client 搭建消费者模块

消费者模块指的是【基础数据项目】【用户项目】【订单项目】【支付项目】，可以理解成spring cloud的一个客户端，而eureka是一个服务端，client是服务端进行注册服务。

eureka统一管理这些服务。

1.创建订单项目

2.选择组件

3.pom文件

主要是spring-cloud-starter-netflix-eureka-client，表示是一个spring cloud的一个客户端，会想eureka注册。

</project>

4.配置主类

package com.cohesion;

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

@SpringBootApplication
@EnableEurekaClient//表示自己是spring cloud的客户端 会想eureka注册
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.启动Spring Cloud Client【订单项目】 8081端口服务

7.启动后查看注册中心是否已经有这个服务

可以看到服务已经注册到注册中心
