spring_cloud_例子

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).

Spring Cloud 为开发者提供了工具
用于快速构建通用模式的分布式系统
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token, 全局锁, 主节点选择, 分布式session, 集群状态

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.

使用样板代码就能快速实现分布式应用

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.
