通过Maven命令创建Web项目

 1. 创建Web项目

     mvn archetype:create

    -DgroupId=com.demo                                          /*项目组标识*/

    -DartifactId=omss                                                /*项目名称*/

    -DarchetypeArtifactId=maven-archetype-webapp  /*Web项目[java项目时无此项]*/

 2. 进入项目目录中，修改pom.xml文件，加入依赖配置，重新编译

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

 3. 将项目转成Eclipse项目

   mvn eclipse:eclipse                         /*生成普通Eclipse项目*/

    mvn eclipse:eclipse -Dwtpversion=1.0  /*生成带WTP的Eclipse项目，版本1.0以上*/
