Spring Cloud Alibaba-创建统一的依赖管理

落日映苍穹つ 2024-03-30 12:12 56阅读 0赞

### 概述 ###

温馨提示

当前 Spring Cloud Alibaba 的 0.2.1.RELEASE 版本基于 Spring Cloud Finchley（F）开发，故在选择 Spring Boot 版本时不要使用 2.1.0 及以上版本（因为 2.1.x 版本必须使用 Spring Cloud Greenwich，俗称 G 版），请使用官方 Demo 中使用的 2.0.6.RELEASE，以免发生意想不到的问题（比如服务无法注册到服务器）

Spring Cloud Alibaba 项目都是基于 Spring Cloud，而 Spring Cloud 项目又是基于 Spring Boot 进行开发，并且都是使用 Maven 做项目管理工具。在实际开发中，我们一般都会创建一个依赖管理项目作为 Maven 的 Parent 项目使用，这样做可以极大的方便我们对 Jar 包版本的统一管理。

### 创建依赖管理项目 ###

创建一个工程名为 `hello-spring-cloud-alibaba-dependencies` 的项目，`pom.xml` 配置文件如下：

> 1.  `<?xml version="1.0" encoding="UTF-8"?>`
> 2.  `<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"`
> 3.  `xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">`

*  parent：继承了 Spring Boot 的 Parent，表示我们是一个 Spring Boot 工程
 *  package：`pom`，表示该项目仅当做依赖项目，没有具体的实现代码
 *  `spring-cloud-alibaba-dependencies`：在 `properties` 配置中预定义了版本号为 `0.2.1.RELEASE` ，表示我们的 Spring Cloud Alibaba 对应的是 Spring Cloud Finchley 版本
 *  build：配置了项目所需的各种插件
 *  repositories：配置项目下载依赖时的第三方库

### 依赖版本说明 ###

项目的最新版本是 0.2.1.RELEASE 和 0.1.1.RELEASE，版本 0.2.1.RELEASE 对应的是 Spring Cloud Finchley 版本，版本 0.1.1.RELEASE 对应的是 Spring Cloud Edgware 版本。

小提示

截止到博客发表时间 `2019 年 01 月 05 日`，项目还处在孵化阶段，故所有版本号都以 `0` 开头；后续肯定会有很多强大的功能帮助我们更好的实现分布式应用的开发；

### 与 Spring Cloud Netflix 的区别 ###

主要增加了 `org.springframework.cloud:spring-cloud-alibaba-dependencies`
