随着现在互联网项目在分布式、微服务上的广泛应用, SpringCloud解决方案也被越来越多的公司所使用。写这个博客主要是为了深入学习相关知识,学习过程中主要参考尚硅谷教程,如有不足之处请指正。
SpringBoot
SpringBoot采用SpringBoot 2.0版本,git源码,新特性可点击链接查看。SpringBoot官方推荐升级到2.0版本
SpringCloud
SpringCloud源码、官网 ,因为Spring Cloud不同其他独立项目,它拥有很多子项目的大项目,Spring Cloud Config,Spring Cloud Netflix,Spring Cloud Bus等,为了防止与这些子系统的版本号混淆,Spring Cloud的版本号全部使用英文单词。




版本名:是伦敦的地铁名
版本号:SR(Service Releases)是固定的 ,大概意思是稳定版本。后面会有一个递增的数字。
GA:(GenerallyAvailable),表示稳定版本
所以 HoxTon.SR12就是HoxTon的第12个Release版本。
SNAPSHOT:快照版本,随时可能修改
M: MileStone,M1表示第1个里程碑版本,一般同时标注PRE,表示预览版版。
SR:Service Release,SR1表示第1个正式版本,一般同时标注
版本号后面的SRX,X代表一个数字,这个是小版本号,就是在特定的版本中,修复一些致命问题,做的升级版本号。所以它是的版本是 版本名+版本号 (如HoxTon.SR12)。
SpringCloud和SpringBoot依赖
SpringCloud和SpringBoot项目依赖使用

在idea 中推荐使用Maven Helper插件,会在pom文件中看到详细的依赖之间关系。 当项目中出现依赖冲突时,可以手动exclude排除依赖




SpringCloud各种组件的停更/升级/替换




老版本使用组件




组件的升级
对于开发人员来说, 版本不停的更新演进, 组件进行、更新、升级、替换,都需要投入精力去学习, 不与时俱进就会被时代所淘汰, 学的头秃==||。
