SpringCloud系列（9）--将服务消费者Consumer注册进Eureka Server

前言：上一章节我们介绍了如何将服务提供者注册进Eureka服务里，本章节则介绍如何将服务消费者Consumer注册进Eureka服务里

Eureka架构原理图

1、修改consumer-order80子模块的pom.xml文件，引入Eureka Clinet的依赖，然后reolad一下，下载依赖

例：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>springcloud01</artifactId>
        <groupId>com.ken.springcloud</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>consumer-order80</artifactId>

    <dependencies>
        <!--以下依赖都没写版本号，没写版本号的情况下会引用父项目的版本-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <!--监控-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
        <!--热部署-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <scope>runtime</scope>
            <optional>true</optional>
        </dependency>
        <!--lombok插件-->
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <!--引入自己定义的api调用包，可以使用Payment模块的entity-->
        <dependency>
            <groupId>com.ken.springcloud</groupId>
            <artifactId>api-commons</artifactId>
            <version>${project.version}</version>
        </dependency>
        <!--Eureka Clinet-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
    </dependencies>

</project>

2、修改consumer-order80子模块的application.yml文件配置的内容，将Eureka相关配置引入

server:
  port: 80  #用80端口是因为浏览器网页服务默认的端口号都是80（80端口是为HTTP开放的）

spring:
  application:
    name: cloud-order-service

eureka:
  client:
    #表示是否将自己注册进Eureka Server里，默认为true
    register-with-eureka: true
    #是否从Eureka Server抓取已有的注册信息，默认为true，单节点无所谓，集群必须设置为true才能配合ribbon使用负载均衡
    fetch-registry: true
    service-url:
      defaultZone: http://localhost:7001/eureka

3、修改consumer-order80子模块的主启动类，将consumer-order80子模块标注为Eureka Client

package com.ken.springcloud;

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

@SpringBootApplication
//标注为Eureka Client（服务注册中心）
@EnableEurekaClient
public class OrderMain {

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

}

效果图：
