IDEA生成 EurekaServer端服务注册中心，类似物业公司

1、建Moudle
cloud-eureka-server7001

2、改pom

    </dependencies>


</project>

3、写yml


server:
  port: 7001

eureka:
  instance:
    hostname: localhost    #eureka服务端的实例名字
  client:
    register-with-eureka: false   #表识不向注册中心注册自己
    fetch-registry: false       #表示自己就是注册中心，职责是维护服务实例，并不需要去检索服务
    service-url:
      #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://${eureka.instance.hostname}:${server.port}/eureka/

4、主启动类

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

5、测试
http://localhost:7001
在这里插入图片描述

Eurekaclient端 cloud- provider-payment8001将注册进 Eurekaserver成为服务提供者 provider,类似学校对外提供授课服务

1、改pom

  <!--声明自己是eureka的客户端        -->
        <!-- https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-starter-eureka-server -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>

2、写yml

server:
eureka:
  client:
    register-with-eureka: true
    fetchRegistry: true
    service-url:
      defaultZone: http://localhost:7001/eureka

3、主启动

@EnableEurekaClient
@SpringBootApplication
public class PayMentMain8001 {
    public static void main(String[] args) {
    SpringApplication.run(PayMentMain8001.class,args);
    }
}

4、测试
先启动EurekaServer7001
然后启动8001
然后访问 http://localhost:7001/
在这里插入图片描述

微服务注册名配置说明
在这里插入图片描述

EurekaClient端 cloud- consumer-order.80将注册进 EurekaServer成为服务消费者 consumer类似来上课消费的同学

1、改pom

 <!-- https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-starter-eureka-server -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>

2、写yml

server:
  port: 80
spring:
  application:
    name: cloud-order-service

eureka:
  client:
    register-with-eureka: true
    fetchRegistry: true
    service-url:
      defaultZone: http://localhost:7001/eureka

3、给主启动加上@EnableEurekaClient

4、测试
先启动7001，再启动8001，再启动80

①然后访问http://localhost:7001
在这里插入图片描述
②http://localhost/consumer/payment/get/2 同样可以拿到结果
