1.项目启动类application.java类名上增加@EnableEurekaServer注解,声明是注册中心
 1 import org.springframework.boot.SpringApplication;
 2 import org.springframework.boot.autoconfigure.SpringBootApplication;
 3 import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
 4 @SpringBootApplication
 5 @EnableEurekaServer
 6 public class EurekaApplication {
 7  public static void main(String[] args) {
 8  SpringApplication.run(EurekaApplication.class, args);
 9  }
10 }

2.application.yml配置:

 1 #配置注册中心服务端信息
 2  eureka:
 3  client:
 4  service-url:
 5  defaultZone: http://localhost:8762/eureka/
 6  #配置是否显示在注册中心上
 7  register-with-eureka: false
 8  #自我保护机制,开发环境可以关闭,生产环境必须开启
 9  server:
10  enable-self-preservation: false
11  #配置在注册中心显示的名字
12  spring:
13  application:
14  name: eureka
15  #配置服务端口
16  #server:
17  #  port: 8761

3.pom.xml配置:

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
