前言

Spring Cloud Alibaba是SpringCloud的子项目，是阿里的微服务解决方案，致力于提供微服务开发的一站式解决方案，包括微服务开发的必备组件。

Spring Cloud Alibaba的整合包括两步：

1、整合SpringCloud 
2、整合SpringCloud Alibaba

整合步骤

版本与兼容性

• Spring Cloud Alibaba基于Spring Cloud，而Spring Cloud基于Spring Boot

Spring Cloud Alibaba 版本说明

• Spring Cloud Alibaba版本说明： spring-cloud-alibaba版本说明

---

• 如上，目前最新版本是：Spring Cloud 2020.0.1+ Spring Cloud Alibaba 2021.1+ Spring Boot 2.4.2，本着不做第一批吃螃蟹的原则，选择Spring Cloud Hoxton.SR9+ Spring Cloud Alibaba 2.2.6.RELEASE+ Spring Boot 2.3.2.RELEASE吧（悄么告诉你们，我是发现Spring Cloud 2020已经不再支持Ribbon了，我才回退版本的。。。）

Spring Cloud 版本说明

• Spring Cloud版本说明：Spring Cloud 版本说明

---

• 如上，我们选择的Spring Cloud版本为Hoxton, 对应的Spring Boot版本为2.2.x, 2.3.x

So，我们这里的整合版本是：
Spring Cloud Hoxton.SR9+ Spring Cloud Alibaba 2.2.6.RELEASE+ Spring Boot 2.3.2.RELEASE

整合Spring Cloud

• pom.xml

<properties>
    <spring-cloud.version>Hoxton.SR9</spring-cloud.version>
</properties>
<dependencyManagement>
    <dependencies>
        <!--整合spring cloud-->
        <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>

整合Spring Cloud Alibaba
