尚硅谷springcloud eureka服务器及微服务入驻（P16~P18）

代码地址

/

eureka-server项目

pom.xml

<dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-netflix-eureka-server</artifactId><version>4.0.3</version><type>pom</type>
</dependency>

这里一定要标记type=pom，不然application,yml文件无法识别

application.yml

server:port: 80server:port: 7001eureka: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:defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/    #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

main文件

package com.tao.springcloud;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloudflix.eureka.server.EnableEurekaServer;@EnableEurekaServer  //加这个注解
@SpringBootApplication
public class EurekaMain7001 {public static void main(String[] args) {SpringApplication.run(EurekaMain7001.class,args);}
}
