概述:
spring boot 2.0相对于之前的版本,变化还是很大的。首先对jdk的版本要求已经不能低于1.8,其次依赖的spring的版本也是最新版本5.0,并集成了功能强大的webflux等。
springcloud finchley 版本的升级也带来了全新组件:spring cloud function 和 spring cloud gateway ,前者致力于函数式编程模块的整合,后者则是网关netflix zuul 的替换组件。

需要注意的地方:
部分依赖做了改变:
旧版本 | finchley 版本 |
---|---|
spring-cloud-starter-eureka-client | spring-cloud-starter-netflix-eureka-client |
spring-cloud-starter-eureka-server | spring-cloud-starter-netflix-eureka-server |
spring-cloud-starter-hystrix | spring-cloud-starter-netflix-hystrix |
spring-cloud-starter-hystrix-dashboard | spring-cloud-starter-netflix-hystrix-dashboard |
spring-cloud-starter-ribbon | spring-cloud-starter-netflix-ribbon |
spring-cloud-starter-turbine | spring-cloud-starter-netflix-turbine |
spring-cloud-starter-zuul | spring-cloud-starter-netflix-zuul |
spring-cloud-starter-feign | spring-cloud-starter-openfeign |
新版本的 springcloud 上面的依赖都发生了变化,依赖中都引入了 netflix,或许是为了声明吧(组件的实现底层并非spring)。
log4j依赖:
在spring cloud之前的版本中,日志只需要引入lombok即可,但是finchley版本需要单独的引用。

4)示例:
注册中心:
可以看到 sc-saturn 已经成功注册到 consul中了。另外,上面的consul ui界面发生了变化,这是1.2版本做出的优化,相较以前的ui界面,已经好看很多了。
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持服务器之家。
