SpringCloud：1章 Eureka服务注册与发现

1. 新建Eureka模块
   
2. 配置yml文件

server:
  port: 2001
eureka:
  instance:
    hostname: localhost  #eurake实例名
  client:
    service-url:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka
    register-with-eureka: false #表示不想注册中心注册自已
    fetch-registy: false #表示不需要检索服务

3.启动类加上@EnableEurekaServer注解

@EnableEurekaServer
@SpringBootApplication
public class DemoApplication {

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

}

4.访问http://localhost:2001/ 出现如下画面则成功

5. 创建注册者模块

6. 配置yml文件

server:
  port: 2002

spring:
  application:
    name: clinet_1 #注册名字

eureka:
  client:
    service-url:
      defaultZone: http://localhost:2001/eureka

7.启动类加入注解@EnableEurekaClient

@EnableEurekaClient
@SpringBootApplication
public class DemoApplication {

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

}

8. 检查依赖是否有这两个

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

9. 访问http://localhost:2001 成功则出现
