环境
spring cloud 介绍
spring cloud 是一系列框架的集合。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。spring cloud 并没有重复制造轮子，它只是将目前各家公司开发的比较成熟、经得起实际考验的服务框架组合起来，通过 spring boot 风格进行再封装屏蔽掉了复杂的配置和实现原理，最终给开发者留出了一套简单易懂、易部署和易维护的分布式系统开发工具包。
spring cloud 对于中小型互联网公司来说是一种福音，因为这类公司往往没有实力或者没有足够的资金投入去开发自己的分布式系统基础设施，使用 spring cloud 一站式解决方案能在从容应对业务发展的同时大大减少开发成本。同时，随着近几年微服务架构和 docker 容器概念的火爆，也会让 spring cloud 在未来越来越“云”化的软件开发风格中立有一席之地，尤其是在目前五花八门的分布式解决方案中提供了标准化的、一站式的技术方案，意义可能会堪比当年 servlet 规范的诞生，有效推进服务端软件系统技术水平的进步。
spring cloud 技术组成
-
eureka

Spring Cloud 对比 Dubbo
-
Dubbo
- Dubbo只是一个远程调用(RPC)框架
- 默认基于长连接,支持多种序列化格式
-
Spring Cloud
- 框架集
- 提供了一整套微服务解决方案(全家桶)
- 基于http调用, Rest API
一、service - 服务
- 商品服务 item service，端口 8001
- 用户服务 user service，端口 8101
- 订单服务 order service，端口 8201
二、commons 通用项目

三、item service 商品服务
- 新建项目
- 配置依赖 pom.xml
- 配置 application.yml
配置主程序- 编写代码
新建 spring boot 起步项目
选择依赖项
- 只选择 web
pom.xml
- 要填加 sp01-commons 项目依赖

spring cloud 介绍
spring cloud 是一系列框架的集合。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。spring cloud 并没有重复制造轮子，它只是将目前各家公司开发的比较成熟、经得起实际考验的服务框架组合起来，通过 spring boot 风格进行再封装屏蔽掉了复杂的配置和实现原理，最终给开发者留出了一套简单易懂、易部署和易维护的分布式系统开发工具包。
spring cloud 对于中小型互联网公司来说是一种福音，因为这类公司往往没有实力或者没有足够的资金投入去开发自己的分布式系统基础设施，使用 spring cloud 一站式解决方案能在从容应对业务发展的同时大大减少开发成本。同时，随着近几年微服务架构和 docker 容器概念的火爆，也会让 spring cloud 在未来越来越“云”化的软件开发风格中立有一席之地，尤其是在目前五花八门的分布式解决方案中提供了标准化的、一站式的技术方案，意义可能会堪比当年 servlet 规范的诞生，有效推进服务端软件系统技术水平的进步。

- 默认基于长连接,支持多种序列化格式
-
Spring Cloud
- 框架集
- 提供了一整套微服务解决方案(全家桶)
- 基于http调用, Rest API
