spring cloud 与spring boot 版本不匹配引发的问题总结

为了将前期项目慢慢转移到微服务上，今天开始搭建eureka服务时，出现以下错误：

经过一番关键字查找，发现spring cloud 与spring boot有着比较严格的版本匹配。不能再像开发单体应用时，随时变更spring boot的版本。

我本次用的版本是：Greenwich.SR3

现将版本对应规则写下来，引用的是其他网友的博客。

来源：https://www.cnblogs.com/it-taosir/p/9979579.html

一、常见版本号说明

　　举个瓜：2.0. RELEASE

　　：主版本号，当功能模块有较大更新或者整体架构发生变化时，主版本号会更新

　　：次版本号。次版本表示只是局部的一些变动。

　　：修改版本号。一般是bug的修改或者是小的变动

　　RELEASE：希腊字母版本号。此版本号用户标注当前版本的软件处于哪个开发阶段

二、希腊字母版本号

　　Base：设计阶段。只有相应的设计没有具体的功能实现。

　　Alpha：软件的初级版本。基本功能已经实现，但存在较多的bug。

　　Bate：相对于Alpha已经有了很大的进步，消除了严重的BUG，但还存在一些潜在的BUG，还需要不断测试。

　　RELEASE：最终版本，没有太大的问题。

三、SpringCloud的版本号

　　）为什么springcloud版本用的是单词而不是数字呢？

　　　　设计的目的是为了更好的管理每个SpringCloud子项目的清单，避免自己的版本号与子项目的版本号混淆。

　　）有什么规则么？

　　　　（常用了英国伦敦地铁站的名称来命名）首字母越靠后表示版本号越大

　　）关于版本发布说明？

　　　　BUILD-XXX　　　　　　开发版　　　　开发团队内部使用，不是很稳定

　　　　GA　　　　　　　　　　稳定版　　　　相比于开发版，基本上可以使用了

　　　　PRE（M1、M2）　　　  里程碑版　　　主要是修复了一些BUG的版本，一个GA后通常有多个里程碑版

　　　　RC　　　　　　　　　　候选发布版　　该阶段的软件类似于最终版的一个发行观察期，基本只修复比较严重的BUG

　　　　SR　　　　　　　　　　正式发布版　　~~~~这个就没啥好说啦

补充：

spring cloud在pom.xml中的版本管理，和我们平时使用的不一样，是在dependencyManagement节点中管理的。完整的xml节点如下：

 <dependencyManagement>
         <dependencies>
             <dependency>
                 <groupId>org.springframework.cloud</groupId>
                 <artifactId>spring-cloud-dependencies</artifactId>
                 <version>${spring-cloud.version}</version>
                 <type>pom</type>
                 <scope>import</scope>
             </dependency>
         </dependencies>
 </dependencyManagement>
