单机Eureka构建步骤

eurekaServer端服务注册中心

IDEA生成eurekaServer端服务注册中心类似物业公司

新建moudle cloud-eureka-server7001

application.yml

server:
  port: 7001


eureka:
  instance:
    hostname: eureka7001.com #eureka服务端的实例名称
  client:
    register-with-eureka: false     #false表示不向注册中心注册自己。
    fetch-registry: false     #false表示自己端就是注册中心，我的职责就是维护服务实例，并不需要去检索服务
    service-url:
      #单机就是7001自己
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

EurekaMain7001.java

@SpringBootApplication
@EnableEurekaServer
public class EurekaMain7001
{
    public static void main(String[] args) {
            SpringApplication.run(EurekaMain7001.class, args);
    }
}

运行测试

cloud-provider-payment8001注册

EurekaClient端cloud-provider-payment8001将注册进EurekaServer成为服务提供者provider，类似尚硅谷学校对外提供授课服务

        <!--eureka-client-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>

eureka:
  client:
    #表示是否将自己注册进EurekaServer默认为true。
    register-with-eureka: true
    #是否从EurekaServer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
    fetchRegistry: true
    service-url:
      #单机版
 #设置与Eureka Server交互的地址查询服务和注册服务都需要依赖这个地址
      defaultZone: http://localhost:7001/eureka

PaymentMain8001添加注解 @EnableEurekaClient

cloud-consumer-order80注册

EurekaClient端cloud-consumer-order80将注册进EurekaServer成为服务消费者consumer,类似来尚硅谷上课消费的各位同学
步骤与8001一致

pom.xml导包

application.yml**

spring:
  application:
    name: cloud-order-service

eureka:
  client:
    #表示是否将自己注册进EurekaServer默认为true。
    register-with-eureka: true
    #是否从EurekaServer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
    fetchRegistry: true
    service-url:
      #单机
      defaultZone: http://localhost:7001/eureka

OrderMain80添加注解 @EnableEurekaClient
