IDEA版SSM入门到实战（Maven+MyBatis+Spring+SpringMVC) -Maven使用前准备

一．Maven准备

注意：IDEA2019.1.x 最高支持Maven的3.6.0

下载地址：http://maven.apache.org/
Maven底层使用Java语言编写的，所以需要配置JAVA_HOME环境变量及Path
将Maven解压非中文无空格目录下
配置MAVEN_HOME 环境变量及Path
新建系统变量MAVEN_HOME,添加变量值maven根目录
编辑系统变量Path，添加变量值%MAVEN_HOME%\bin
输入【cmd】,进入命令行窗口，输入**【mvn -v】** ，检查Maven环境是否搭建成功

二．Maven基本配置

Maven配置文件位置：maven根目录/conf/settings.xml

设置本地仓库【默认：C:/用户家目录/.m2/repository】

xml 复制代码

<!-- localRepository
   | The path to the local repository maven will use to store artifacts.
   |
   | Default: ${user.home}/.m2/repository
  <localRepository>/path/to/local/repo</localRepository>
  -->
  <localRepository>E:\SG_220106\LocalRepository</localRepository>

设置阿里云镜像服务器

xml 复制代码

<mirrors>
    <!-- mirror
     | Specifies a repository mirror site to use instead of a given repository. The repository that
     | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
     | for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
     |
    <mirror>
      <id>mirrorId</id>
      <mirrorOf>repositoryId</mirrorOf>
      <name>Human Readable Name for this Mirror.</name>
      <url>http://my.repository.com/repo/path</url>
    </mirror>
     -->
	 <mirror>
        <id>nexus-aliyun</id>
        <mirrorOf>central</mirrorOf>
        <name>Nexus aliyun</name>
        <url>http://maven.aliyun.com/nexus/content/groups/public</url>
    </mirror>
  </mirrors>

设置使用JDK版本【1.8|JDK8】

xml 复制代码

<profiles>
<profile>
      <id>jdk-1.8</id>
      <activation>
        <activeByDefault>true</activeByDefault>
        <jdk>1.8</jdk>
      </activation>
      <properties>
        <maven.compiler.source>1.8</maven.compiler.source>
        <maven.compiler.target>1.8</maven.compiler.target>
        <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
      </properties>
    </profile>
  </profiles>
