SpringBoot與SpringCloud的版本對應詳細版

緣起

初學spring cloud的朋友可能不知道，其實SpringBoot與SpringCloud需要版本對應，否則可能會造成很多意料之外的錯誤，比如eureka註冊了結果找不到服務類啊，比如某些jar導入不進來啊，等等這些錯誤。下面列出來springBoot和spring cloud的版本對應關係，需要配套使用，纔不會出現各種奇怪的錯誤。

關於maven倉庫的版本列表

spring-cloud-dependencies 版本列表可查看：
https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-dependencies
spring-boot-starter-parent 版本列表可查看：
https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-parent

版本對應關係

大版本對應：

Spring Cloud	Spring Boot
Angel版本	兼容Spring Boot 1.2.x
Brixton版本	兼容Spring Boot 1.3.x，也兼容Spring Boot 1.4.x
Camden版本	兼容Spring Boot 1.4.x，也兼容Spring Boot 1.5.x
Dalston版本、Edgware版本	兼容Spring Boot 1.5.x，不兼容Spring Boot 2.0.x
Finchley版本	兼容Spring Boot 2.0.x，不兼容Spring Boot 1.5.x

在實際開發過程中，我們需要更詳細的版本對應：

Spring Boot	Spring Cloud
1.5.2.RELEASE	Dalston.RC1
1.5.9.RELEASE	Edgware.RELEASE
2.0.2.RELEASE	Finchley.BUILD-SNAPSHOT
2.0.3.RELEASE	Finchley.RELEASE

關於spring cloud1.x版本和2.x版本區別

spring cloud各個版本之間是有所區別的，比如在SpringCloud中，1.X和2.X版本在pom.xml中引入的jar包名字都不一樣，比如有的叫spirng-cloud-starter-hystrix 有的叫spring-cloud-netflix-hystrix，維護起來會比較困難。

1.x版本pom.xml裏幾個基本用到的jar長這樣：

	            <scope>test</scope>

	    </dependencies>
	</project>

而在2.x版本中，比如我們需要eureka,去maven倉庫中可能會看到deprecated, please use spring-cloud-starter-netflix-eureka-client這類提示，包括使用ribbon也會有


所以個人猜測2.x中統一用
spring-cloud-starter-netflix-xx 替換了原有的 spring-cloud-starter-xx(此處如有不正確請指出)
所以2.x的版本pom.xml類似如下這樣

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
