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
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>
