springCloud是基于springboot搭建的微服务。它利用Spring Boot的开发便利性巧妙地简化了分布式系统基础设施的开发,如服务发现注册、配置中心、消息总线、负载均衡、断路器、数据监控等,都可以用Spring Boot的开发风格做到一键启动和部署。

3.在该module下的src/main/resources文件夹下,新建文件application.yml
六、启动服务
先启动discovery模块,再启动其他模块
在浏览器依次输入:
http://localhost:8081/
http://localhost:8082/service
http://localhost:8083/service2
http://localhost:8084/service/service
http://localhost:8084/service2/service2
