Maven的作用是来管理项目依赖构件（jar包）
1. 下载Maven
官方地址：http://maven.apache.org/download.cgi

2. 解压并新建一个本地库文件夹E:\MavenRepository
3.在settings.xml中配置本地仓库路径及国内镜像服务器地址

Maven国内镜像仓库：
http://maven.aliyun.com/nexus/content/groups/public
<localRepository>E:\MavenRepository</localRepository>
<mirrors>
<!--
<mirror>
<id>alimaven</id>
<mirrorOf>central</mirrorOf>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/repositories/central/</url>
</mirror>
<mirror>
<id>jboss-public-repository-group</id>
<mirrorOf>central</mirrorOf>
<name>JBoss Public Repository Group</name>
<url>http://repository.jboss.org/nexus/content/groups/public</url>
</mirror>
-->
<mirror>
<id>alimaven</id>
<mirrorOf>central</mirrorOf>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/groups/public</url>
</mirror>
</mirrors>
<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>
若有代理请添加配置：
<proxies>
<proxy>
<id>my-proxy</id>
<active>true</active>
<protocol>http</protocol>
<host>192.168.181.238</host>
<port>8080</port>
</proxy>
</proxies>
4.配置maven环境变量

5.IDE配置

6.新建Maven项目

这里maven会自动下载需要的构件，完成后项目目录结构如下图

pom.xml报错原因是，因为创建的是JavaEE工程，需要添加web.xml，在工程上右键

将对应项目的文件可以拷贝到对应的maven项目目录下
7.配置pom.xml
