微服务Microservice,跟之相对应的是将功能从开发到交付都打包成一个很大的服务单元,一般称之为Monolith,也称「巨石」架构。微服务实现和实施思路更强调功能单一,服务单元小型化和微型化,倡导将服务粒度做小,使它可以独立承担对外服务的职责。
Spring Cloud是一个基于Spring Boot实现的云应用开发工具,它为基于JVM的云应用开发中的配置管理、服务发现、断路器、智能路由、微代理、控制总线、全局锁、决策竞选、分布式会话和集群状态管理等操作提供了一种简单的开发方式。
接下来会以一个简单的demo来学习Spring Cloud ,地址在github,demo使用maven构建。
包含几个子module
server-discovery:服务发现
config-service:配置服务
user-provider-service:服务提供者
user-ui: 消费者,web前端展示
api-gateway: 服务网关
首先配置hosts,操作都以域名访问 127.0.0.1 discovery config gateway
demo中的代码参考(抄袭)自 https://github.com/kbastani/spring-cloud-microservice-example 和 http://blog.didispace.com/springcloud5/ 以及http://git.oschina.net/itmuch/spring-cloud-study
创建父级项目 spring-cloud-demo,pom文件内容
