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

一．Maven准备

• 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
• 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】

  <!-- 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

  <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】

  <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>
