我不知道大家有没有遇到过,很多面试官上来就是谈谈你对分布式的理解,接着就是什么是微服务,再接着就是SpringCloud用过?能不能谈一谈,同一个坑我踩了好多次,面试的时候总是祈祷不要来这些了,然而上天从来没有把我的祷告听进去,那也好,就来学一波吧!最好的理解就是自己玩一下这个框架!
由于时间关系快1点了,我先暂时编辑写一个注册中心的搭建,底下每天我写一些,一是相当于笔记,二是希望有人给我提建议。
我先谈一谈搭建springboot+springcloud这个框架:
1.首先搭建一个搭建一个注册中心euerka(这边没坑非常简单)
(1) pom.xml文件

(2)application-dev.properties
server.port=8081
eureka.instance.hostname=localhost
eureka.instance.client.registerWithEureka=false
eureka.instance.client.fetchRegistry=false
eureka.instance.client.serviceUrl.defaultZone=http://${eureka.instance.hostname}:${server.port}/eureka/
spring.application.name= demo-eureka
(3)eurekaApplication
@EnableEurekaServer
@SpringBootApplication
public class YunApplication {
public static void main(String[] args) {
SpringApplication.run(YunApplication.class, args);
}
}
4. 启动YunApplication,浏览器输入http://localhost:8081/,显示如下证明euerka搭建成功
