尚硅谷2020最新版SpringCloud(H版&alibaba)框架开发教程全套完整版从入门到精通1 - 版本概述

 

 

在springboot学习后,了解到springboot是一种技术

springcloud是一揽子微服务的解决方案

https://www.cnblogs.com/ukzq/p/11124786.html SpringCloud分布式系统的演进.

https://www.cnblogs.com/ukzq/p/10358946.html 什么是SpringCloud.

https://www.cnblogs.com/ukzq/p/11422887.html 在IDEA编辑器中建立Spring Cloud的子项目包(构建微服务).

https://www.cnblogs.com/ukzq/p/11473929.html 趋势投资tz-proj springcloud (vue redis).

感觉只是上手做过几个demo,还是有些不能完全理解微服务

eureka已经停更,要不使用dubbo-zookeeper,要不使用nacos

Do you know when you speak less your thoughts spring.

微服务架构是一种架构模式,它提倡将单一应用程序划分成一组小的服务,服务之间互相协调,互相配合,为用户提供最终价值.

每个服务运行在其独立的进程中,服务与服务间采用轻量级的通信机制互相协作(通常是基于HTTP协议的RESTful API),每个

服务都围绕着具体业务进行构建,并且能够被独立地部署到生产环境,类生产环境等.另外,应当尽量避免统一的,集中式的服务

管理机制,对具体的一个服务而言,应根据业务上下文,选择合适的语言,工具对其进行构建.

 

 

 

 

 p3:指定springboot,springcloud的版本

 

 

 

 强烈推荐升级2.0以后

 

 起步支持java 8,也支持java 9

 

 

截至2020-03-07,springboot最新版本为 2.2.5

但不一定要用最新的版本

springcloud 的 github 已经不维护

springcloud版本是根据英国地铁站A,B,C....H开头来命名

 

现在的最新版本 H打头版本

GA:General Availability,正式发布的版本，官方推荐使用此版本。在国外都是用GA来说明release版本的。

PRE: 预览版,内部测试版. 主要是给开发人员和测试人员测试和找BUG用的，不建议使用；

SNAPSHOT: 快照版，可以稳定使用，且仍在继续改进版本

 

如果你的springcloud是H版,那么springboot必须是2.2.x开始

区间还是要选择,还是看官方推荐的
