详解Idea SpringBoot搭建SpringCloud的准备工作(推荐)

<groupId>org.example</groupId>
  <artifactId>spring-cloud</artifactId>
  <version>1.0-SNAPSHOT</version>
<!--  注意一定要改成pom-->
  <packaging>pom</packaging>
<!--这是一个子工程-->
  <modules>
    <module>cloud-provider-payment8001</module>
  </modules>

 <!-- 统一管理jar包版本-->
  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
<!--    单元测试的-->
    <junit.version>4.13</junit.version>
    <log4j.version>1.2.17</log4j.version>
    <lombok.version>1.18.12</lombok.version>
    <mysql.version>8.0.21</mysql.version>
<!--    这是德鲁伊的（数据库连接池）-->
    <druid.version>1.1.16</druid.version>
    <mybatis.spring.boot.version>2.1.3</mybatis.spring.boot.version>
<!--    截至2020/10/1日之前根据官方文档cloud 的版本Hoxton.SR8 和spring boot的2.3.3.RELEASE最配-->
    <spring.cloud-version>Hoxton.SR8</spring.cloud-version>
    <spring.boot-version>2.3.3.RELEASE</spring.boot-version>
  </properties>

<!-- 提供统一版本作为版本锁定  子工程就不用写 groupId和version
dependencyManagement只是管理版本号（父项目和子项目统一版本号），真正干活有用的还是dependencies-->
