博客主要介绍了Eureka Server和Eureka Client的相关内容，包括两者所需的依赖、application.yml配置，还提到Eureka Server将自身注册到其他eureka服务商以及启动类注解，Eureka Client的启动注解等信息技术关键信息。

Eureka Server

依赖

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

application.yml
将自身注册到其他eureka服务商

spring:
  application:
    name: eureka1
eureka:
  client:
       service-url:
            defaultZone: http://localhost:20002/eureka

启动类注解

@EnableEurekaServer

Eureka Client

依赖

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

application.yml

spring:
  application:
    name: name
eureka:
  client:
       service-url:
            defaultZone: http://localhost:20002/eureka
       #是否注册自身到自身
       register-with-eureka: true
       #是否拉取服务列表
       fetch-registry: false
       #每隔30秒从服务器获取服务列表
       registry-fetch-interval-seconds:  30
   instance:
       #指定Eureka获取到的ip地址
       prefer-ip-address: true
       ip-address: 127.0.0.1
       #心跳包发送时间间隔
       lease-renewal-inerval-in-seconds: 30
       #失效剔除
       lease-expiration-duration-in-seconds: 90  
     
# Ribbon负载均衡配置
ribbon:
  ConnectionTimeout: 1000
  ReadTimeout: 2000
  MaxAutoRetries: 0
  MaxAutoRetriesNextServer: 0

启动注解

@EnableDiscoveryClient

@SpringCloudApplication = @SpringBootApplication + @EnableDiscoveryClient +  @EnableCircuitBreaker
