版本說明

首先這三者版本對應關係參照官網地址版本說明，如下所示

本學習專案採用Spring Cloud Alibaba 2.2.7.RELEASE版本

父模組搭建

用於統一專案Spring Boot、Spring Cloud、Spring Cloud Alibaba版本。

先使用IDEA新鍵一個Empty Project，作為專案根目錄。然後此目錄下新鍵模組，pom內容如下所示

<?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>
 

其它專案繼承該模組即可，舉例如下

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