我想知道Springboot和Springcloud之间是否存在兼容性矩阵?
我在STS上创建了一个简单的项目,并且遇到了兼容性问题。
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.1.RELEASE</version>
<relativePath /> <!-- lookup parent from repository -->
</parent>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>Camden.SR5</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
充分了解Springboot和Springcloud的受支持版本将使事情变得更简单。
我确实观察到了一个关于这种需求的公开问题 - https://github.com/spring-cloud/spring-cloud-build/issues/43
社区是否有办法在他们开始使用SpringCloud项目时如何选择开始使用特定版本组合?
编辑:添加我自昨天以来遇到的此类问题的另一个实例
来自pom.xml的片段
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.2.RELEASE</version>
<!--<version>1.5.2.RELEASE</version> -->
<relativePath /> <!-- lookup parent from repository -->
</parent>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<!-- <version>Camden.SR6</version -->
<!-- <version>Brixton.SR5</version> -->
<!-- <version>Camden.SR6</version> -->
<version>Camden.SR5</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
使用带有Camden.SR5的1.5.2.RELEASE时没有maven错误,但是当应用程序启动时会抛出NoClassDefFoundError。

在Brixton.SR6中使用1.4.5是一种通常适用于我的组合。

如果您按照http://projects.spring.io/spring-cloud/上的快速入门,它会告诉您兼容的版本。 Camden版本系列与Spring Boot 1.5.x不兼容
您还可以阅读每个版本的发行说明,其中包含兼容的组件版本:
https://github.com/spring-projects/spring-cloud/wiki/Spring-Cloud-Camden-Release-Notes:
Spring Cloud Camden构建于Spring Boot 1.4.x之上。

是的,有:http://start.spring.io/actuator/info
除了弹簧云之外,它还包含更多的库,但其中每个库都不是一个。

2020年,找到最新的匹配版本仍然很麻烦...
Release Trains
表中查找,然后选择所需的Spring Boot版本和Spring Cloud Release Train。另一个信息来源是Spring Blog类别“发布”:https://spring.io/blog/category/releases,但是恕我直言,这有点...令人困惑。
