二 工程搭建

2.1 工程结构

2.2 配置pom

2.3 application配置文件

spring:
  application:
    name: spt-ds-eureka-server

server:
  port: 53000 #启动端口

eureka:
  server:
    enable-self-preservation: false    #关闭服务器自我保护，客户端心跳检测15分钟内错误达到80%服务会保护，导致别人还认为是好用的服务
    eviction-interval-timer-in-ms: 10000 #清理间隔（单位毫秒，默认是60*1000）5秒将客户端剔除的服务在服务注册列表中剔除#
    shouldUseReadOnlyResponseCache: true #eureka是CAP理论种基于AP策略，为了保证强一致性关闭此切换CP 默认不关闭 false关闭
  client:
    register-with-eureka: false  #false:不作为一个客户端注册到注册中心
    fetch-registry: false      #为true时，可以启动，但报异常：Cannot execute request on any known server
    instance-info-replication-interval-seconds: 10
    serviceUrl:
      defaultZone: http://localhost:${server.port}/eureka/
  instance:
    hostname: ${spring.cloud.client.ip-address}
    prefer-ip-address: true
    instance-id: ${spring.application.name}:${spring.cloud.client.ip-address}:${spring.application.instance_id:${server.port}}

 2.4 启动类

package com.ljf.springsecurity.oauth;

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

/**
 * Hello world!
 *
 */
@SpringBootApplication
@EnableEurekaServer
public class App 
{
    public static void main( String[] args )
    {

        SpringApplication.run(App.class,args);
        System.out.println("eureka服务启动成功！");
    }
}
