1.springCloud 注册中心

1.版本控制

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.9.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    ...
    <properties>
        <java.version>1.8</java.version>
        <spring-cloud.version>Greenwich.SR3</spring-cloud.version>
    </properties>

2.添加@EnableEurekaServer

package cn.lovingliu.loving;

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

@SpringBootApplication
@EnableEurekaServer
public class LovingApplication {

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

}

3.配置application.yml

eureka:
  client:
    fetch-registry: false # 该应用为注册中心 只用维护服务实例,无需检索服务
    register-with-eureka: false # eureka 即是服务端又是服务端,且该应用是一个注册中心,所以取消向注册中心注册自己
    service-url: # 地址
      defaultZone: http://127.0.0.1:1000/eureka
  server: #自我保护模式关闭 在注册中心会一直提示
    enable-self-preservation: false
  instance: #使用主机的IP地址来定义注册中心的地址
    prefer-ip-address: true
spring:
  application:
    name: eureka
server:
  port: 1000
