上一章搭建了eureka注册中心,这章就写搭建一个client服务注册到注册中心上去。

yml文件:
###服务启动端口号
server:
port: 8082
###服务名称(服务注册到eureka名称)
spring:
application:
name: zsy-app
###服务注册到eureka地址
eureka:
client:
service-url:
defaultZone: http://localhost:8081/eureka
###册自己到注册中心
register-with-eureka: true
###是否需要从eureka上获取注册信息
fetch-registry: true
# 心跳检测检测与续约时间
# 测试时将值设置设置小些,保证服务关闭后注册中心能及时踢出服务
instance:
###Eureka客户端向服务端发送心跳的时间间隔,单位为秒(客户端告诉服务端自己会按照该规则)
lease-renewal-interval-in-seconds: 1
####Eureka服务端在收到最后一次心跳之后等待的时间上限,单位为秒,超过则剔除(客户端告诉服务端按照此规则等待自己)
lease-expiration-duration-in-seconds: 2
启动类:
package com.zsy.cloud.eureka_client;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
@SpringBootApplication
@EnableEurekaClient
public class ClientApplication {
public static void main(String[] args) {
SpringApplication.run(ClientApplication.class, args);
}
}
加入@EnableEurekaClient注解使其成为eureka的client
再次访问eureka的管理后台:

发现client已成功注册进来。
