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注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的版本對應關系,需要配套使用,才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
版本對應關系
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 |
Greenwich版本 | 兼容Spring Boot 2.1.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里幾個基本用到的jar長這樣:
<project xmlns="http://maven.apache.org/POM/4.0.0"

</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">
