1.打开eclipse，文件-新建-其他，选择Maven Project

2.第一个打上勾，并输入存储目录

3.下一步，这里的Packing 选择 war的形式

4.由于packing是war包，那么下面也就多出了webapp的目录

5.由于我们的项目要使用eclipse发布到tomcat下面，这里我们需要先把项目转成dynamic web project 在我们的项目上点击右键，选择properties 并找到 Project Facets ，并点击Convert to faceted form… 然后勾选Dynamic Web Module 并点击ok 如下图：(3.0只有tomcat7才支持)

6.自己在webapp文件夹下新建两个目录 META-INF ，WEB-INF

7.然后我们要修改发布规则，右键点击项目，选择 Deployment Assembly

应该是这个样子

8.至此一个基于maven的webapp就建立好了，并可以直接从eclipse中发布到tomcat中

补充：我们需要在src/main/webapp/WEB-INF下面创建一个web.xml

<?xml version="1.0" encoding="UTF-8"?>

在src/main/java/下新建config目录

新建applicationContext.xml

在src/main/java/下新建config目录

新建config.properties
