?idea新建一個(gè)eureka?server服務(wù)

application.yml?配置：

spring:application:name: eureka-serverserver:port: 7000eureka:instance:hostname: localhostserver:response-cache-update-interval-ms: 3000enable-self-preservation: false #設(shè)為false，關(guān)閉自我保護(hù)主要eviction-interval-timer-in-ms: 3000 #清理間隔（單位毫秒，默認(rèn)是60*1000）client:#表示是否將自己注冊(cè)到Eureka Serverregister-with-eureka: falsefetch-registry: falseserviceUrl:defaultZone: http://localhost:${server.port}/eureka/

通過(guò)@EnableEurekaServer?開(kāi)啟

package com.example.eureka;import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;@SpringBootApplication @EnableEurekaServer public class EurekaApplication {public static void main(String[] args) {SpringApplication.run(EurekaApplication.class, args);}}

啟動(dòng)服務(wù)，訪(fǎng)問(wèn)?localhost:7000,可以看到eureka界面如下，這時(shí)候沒(méi)有服務(wù)注冊(cè)在eureka：

新建一個(gè)eureka-discovery服務(wù)，注冊(cè)在eureka?server中

pom.xml中主要需要引入：

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

application.yml中配置如下： server:port: 7001spring:application:name: eureka-discoveryeureka:client:serviceUrl:defaultZone: http://localhost:7000/eureka/ instance:lease-expiration-duration-in-seconds: 2#服務(wù)刷新時(shí)間配置，每隔這個(gè)時(shí)間會(huì)主動(dòng)心跳一次#默認(rèn)30slease-renewal-interval-in-seconds: 1#將ip注冊(cè)到eureka server上而不是機(jī)器主機(jī)名prefer-ip-address: true#ip-address: 127.0.0.1#InstanceId默認(rèn)是${spring.cloud.client.hostname}:${spring.application.name}:${spring.application.instance_id:${server.port}},#也就是：主機(jī)名：應(yīng)用名：應(yīng)用端口#通過(guò)instance-id 自定義ip+端口號(hào)instance-id: ${spring.cloud.client.ipaddress}:${server.port}

啟動(dòng)類(lèi)EurekaDiscoveryApplication中配置@EnableEurekaClient

package com.example.eurekadiscovery;import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.netflix.eureka.EnableEurekaClient;@SpringBootApplication @EnableEurekaClient public class EurekaDiscoveryApplication {public static void main(String[] args) {SpringApplication.run(EurekaDiscoveryApplication.class, args);}}

啟動(dòng)eureka-discovery服務(wù)

再訪(fǎng)問(wèn)http://localhost:7000/,可以發(fā)現(xiàn)eureka-discovery已經(jīng)注冊(cè)在eureka server:
