Spring Cloud服务注册-eureka部署

开篇建议初学者：
1、选择ide自带的依赖
2、如果手动配置pom，请查看好springboot对应springcloud的版本号

• intellij idea
• tomcat
• jar 8

创建spring项目
new->project

选择 spring cloud discovery-> eureka server

next->完成

如果在idea直接选择的eureka server，会自动生成pom.xml，无需配置

注：“spring-cloud-starter-eureka-server”已经过期，改为“spring-cloud-starter-netflix-eureka-server”

配置 application.properties

server.port=1010
#表示是否将自己注册到Eureka Server
eureka.client.registerWithEureka=false
#表示是否从Eureka Server获取注册信息
eureka.client.fetchRegistry=false

#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
eureka.client.serviceUrl.defaultZone=http://localhost:${server.port}/eureka/

启动类添加@EnableEurekaServer

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
@EnableEurekaServer
public class B2cApplication {

    public static void main(String[] args) {
        SpringApplication.run(B2cApplication.class, args);
    }

}

编译->运行
