Spring Cloud 简介
Spring Cloud provides tools for developers to quickly build some of the common patterns in distributed systems (e.g. configuration management, service discovery, circuit breakers, intelligent routing, micro-proxy, control bus, one-time tokens, global locks, leadership election, distributed sessions, cluster state). Coordination of distributed systems leads to boiler plate patterns, and using Spring Cloud developers can quickly stand up services and applications that implement those patterns. They will work well in any distributed environment, including the developer’s own laptop, bare metal data centres, and managed platforms such as Cloud Foundry.
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。
Spring Cloud包含了多个子项目（针对分布式系统中涉及的多个不同开源产品），比如：Spring Cloud Config、Spring Cloud Netflix、Spring Cloud Bus 、Spring Cloud CloudFoundry、Spring Cloud Stream、Spring Cloud Security、Spring Cloud Task、Spring Cloud Zookeeper、Spring Cloud Consul、Spring Cloud CLI等项目。
Spring Cloud 所包含项目的一个大概结构如下：
