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

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-serviceeureka:client:#表示是否将自己注册进Eureka Server里，默认为trueregister-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: trueservice-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：
