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：
| 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。
|
1 2 3 4 5 6 7 8 9 10 11 |
<!--lombok--> <dependency> <groupid>org.projectlombok</groupid> <artifactid>lombok</artifactid> </dependency>
<dependency> <groupid>log4j</groupid> <artifactid>log4j</artifactid> <version> 1.2 . 17 </version> </dependency> |
2）集成consul配置文件：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 |
spring: application: name: sc-saturn profiles: active: dev
cloud: config: # uri: http: //localhost:9999 discovery: enabled: false serviceid: sc-earth-config-server label: master profile: pre consul: host: http: //localhost:8500 port: 80 discovery: prefer-ip-address: true #这里是重写健康检查的endpoint，默认为 /health，重写是为了节省不必要的网络传输，只需要http 200 状态码即可 health-check-path: /ok/health heartbeat: enabled: false |
3）启动类：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
@springbootapplication @enablefeignclients @enablezuulserver @componentscan (basepackages={ "com.iyb.ak" }) @enablediscoveryclient @slf4j public class saturnapplication implements commandlinerunner{
public static void main(string[] args) { springapplication.run(saturnapplication. class , args); }
@override public void run(string... args) throws exception { log.info( ">>>>>>>>>>>>>>> sc-saturn 启动完成<<<<<<<<<<<<<" ); } } |
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。
