Spring Cloud Alibaba学习项目环境搭建

版本说明

首先这三者版本对应关系参照官网地址版本说明，如下所示

Spring Cloud Alibaba Version	Spring Cloud Version	Spring Boot Version
2021.0.1.0	Spring Cloud 2021.0.1	2.6.3
2.2.7.RELEASE	Spring Cloud Hoxton.SR12	2.3.12.RELEASE
2021.1	Spring Cloud 2020.0.1	2.4.2
2.2.6.RELEASE	Spring Cloud Hoxton.SR9	2.3.2.RELEASE
2.1.4.RELEASE	Spring Cloud Greenwich.SR6	2.1.13.RELEASE
2.2.1.RELEASE	Spring Cloud Hoxton.SR3	2.2.5.RELEASE
2.2.0.RELEASE	Spring Cloud Hoxton.RELEASE	2.2.X.RELEASE
2.1.2.RELEASE	Spring Cloud Greenwich	2.1.X.RELEASE
2.0.4.RELEASE(停止维护，建议升级)	Spring Cloud Finchley	2.0.X.RELEASE
1.5.1.RELEASE(停止维护，建议升级)	Spring Cloud Edgware	1.5.X.RELEASE

本学习项目采用Spring Cloud Alibaba 2.2.7.RELEASE版本

父模块搭建

用于统一项目Spring Boot、Spring Cloud、Spring Cloud Alibaba版本。

先使用IDEA新键一个Empty Project，作为项目根目录。然后此目录下新键模块，pom内容如下所示

<?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 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>

  <groupId>com.wangtao</groupId>
  <artifactId>springcloud-alibaba-parent</artifactId>
  <packaging>pom</packaging>
  <version>1.0-SNAPSHOT</version>

  <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.3.12.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
  </parent>

  <properties>
    <spring-cloud.version>Hoxton.SR12</spring-cloud.version>
    <spring-cloud-alibaba.version>2.2.7.RELEASE</spring-cloud-alibaba.version>
  </properties>

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

</project>

其它项目继承该模块即可，举例如下

<parent>
    <groupId>com.wangtao</groupId>
    <artifactId>springcloud-alibaba-parent</artifactId>
    <version>1.0-SNAPSHOT</version>
    <relativePath>../springcloud-alibaba-parent/pom.xml</relativePath>
</parent>
