2、确定版本
Spring Cloud：Spring Cloud Hoxton.SR12
Spring Cloud Alibaba：2.2.8.RELEASE
Spring Boot：2.3.12.RELEASE
3、搭建
（1）新建一个maven项目，删除不必要文件，最终目录结构
（2）修改POM文件
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.shiwn</groupId> <artifactId>spring-cloud-alibaba</artifactId> <version>0.0.1-SNAPSHOT</version> <name>spring-cloud-alibaba</name> <packaging>pom</packaging> <description>Demo project for Spring Boot</description> <properties> <!-- java版本 --> <java.version>1.8</java.version> <!-- SpringBoot 版本 --> <spring.boot.version>2.3.12.RELEASE</spring.boot.version> <!-- Spring Cloud Alibaba 版本 --> <spring.cloud.alibaba>2.2.8.RELEASE</spring.cloud.alibaba> <!-- Spring Cloud 版本 --> <spring.cloud>Hoxton.SR12</spring.cloud> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> <!-- 版本依赖统一管理 --> <dependencyManagement> <dependencies> <!-- SpringBoot 版本 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>${spring.boot.version}</version> <type>pom</type> <scope>import</scope> </dependency> <!-- Spring Cloud Alibaba 版本 --> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-alibaba-dependencies</artifactId> <version>${spring.cloud.alibaba}</version> <type>pom</type> <scope>import</scope> </dependency> <!-- Spring Cloud 版本 --> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>${spring.cloud}</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> </project>
