spring-cloud入门(二):eureka-client(服务注册)

前言

上一节我们搭建起了服务注册中心,为各个服务提供者和消费者提供一个桥梁,这一节我们搭建一个服务提供者,注册到注册中心

server.port=8764

eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka/

spring.application.name=service-say

到此项目搭建完成

启动项目

启动eureka-client之前,我们先启动上一节搭建的eureka-server,两个服务都启动好以后,我们访问注册中心,可以看到:

说明我们服务注册成功!访问一下http://127.0.0.1:8764/hi?name=hornet

到此,eureka-client(服务发现)项目搭建成功。
