本文描述如何确定微服务项目的Spring Boot、Spring Cloud、Spring Cloud Alibaba的版本。

1. 版本选择

我们知道Spring Boot、Spring Cloud、Spring Cloud Alibaba的版本选择一致性非常重要。在选择Spring Boot和Spring Cloud版本时，需要考虑到两者之间的关系以及项目的具体需求。

首先，Spring Boot和Spring Cloud有密切的联系。Spring Boot是Spring Cloud的基础，版本选择应该先确定Spring Boot的版本，然后再选择与之兼容的Spring Cloud版本。

3者的版本选择可以参考：Spring Cloud Alibaba版本选择参考。简单起见也可以使用阿里巴巴提供的云原生应用脚手架

其他版本参考：https://sca.aliyun.com/zh-cn/docs/2022.0.0.0/overview/version-explain（先选择Spring Boot版本）

2. 用脚手架快速生成微服务的pom.xml

• 访问https://start.aliyun.com/

• 填写项目的基本信息

3、选择了3个组件，一个来自Spring Cloud，一个来自Spring Cloud Alibaba，所以会帮我们在pom.xml文件中引入2个框架的依赖。

• 可以选择下载代码或在线浏览代码。我这里把pom.xml文件的内容贴出来。

原始内容如下：

<?xml version="1.0" encoding="UTF-8"?>

由于有些内容我们暂时用不到，这里主要是为了帮我们解决版本的选择问题，所以下面我们只保留了元素，且强制给子模块添加了lombok、spring测试框架，所以最终的父项目的pom.xml内容如下：

• 至此由于pom.xml的建立，微服务的父工程已经建立好

3. 创建一个父工程
