概述
Spring Cloud 利用 Spring Boot 特性整合了开源行业中优秀的组件，整体对外提供了一套在微服务架构中服务治理的解决方案。
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为开发人员提供了工具，以快速构建分布式系统中的一些常见模式（例如，配置管理，服务发现，断路器，智能路由，微代理，控制总线，一次性令牌，全局锁，领导选举，分布式会话，群集状态）。分布式系统的协调导致了样板式样，并且使用Spring Cloud开发人员可以快速支持实现这些样板的服务和应用程序。它们可以在任何分布式环境中正常工作，包括开发人员自己的笔记本电脑，裸机数据中心以及Cloud Foundry等托管平台。
