# 创建一个新Maven项目 #

*  new 一个project

![技术分享][797348-20160224215012240-1065055961.png]

*  不选择任何Maven模板

![技术分享][797348-20160224215039974-537020396.png]

*  起个GroupId、ArifactId

![技术分享][797348-20160224215124583-1065420029.png]

*  起个项目名。注意：Idea\_Project是存放此项目的工作区间，mavenDemo\_idea15为存放此项目的子目录。

![技术分享][797348-20160224215235005-1391385829.png]

*  建好项目后，打开，点击Auto-Import

![技术分享][797348-20160224215419802-817948119.png]

*  下面为此项目的结构

# 项目部署 #

*  点击

## Project: 无需设置 （当然可点击Project complier output自定义编译目录） ##

![技术分享][797348-20160224215607771-1984494060.png]

## Modules:可看到此项目无任何适配服务组件（因为是手工创建Maven，没有选择任何Maven模板）--因此需要我们进行添加。 ##

![技术分享][797348-20160224215919396-86983636.png]

*  选择Web（为此项目添加Web服务组件，这便是一个Web项目了）

![技术分享][797348-20160224220134802-1514004998.png]

*  现在为Web设置资源目录。双击Web Resource Directory

![技术分享][797348-20160224220305380-142824778.png]

*  选择scr/main目录

![技术分享][797348-20160224220559458-128756380.png]

*  在后面加上webapp。好了，点OK，Web的资源目录便设置好了。

![技术分享][797348-20160224220655130-1637259503.png]

*  现在设置Web的描述文件的目录

![技术分享][797348-20160224220749411-825717204.png]

*  设置在webapp/WEB-INF/web.xml目录下

![Center][]

## Facts: 表示当前项目的适配服务组件。可看到此项目已是一个Web项目了。 ##

![技术分享][797348-20160224221000458-1246044489.png]

## Aftifacts: 这个Aftifacts描述了当前项目发布的信息。现在进行添加，从Modeles中选择。 ##

![技术分享][797348-20160224221233786-1051320504.png]

![技术分享][797348-20160224222957521-83778449.png]

说明：A: 现在Artifacts已有了发布的项目了（idea中准确的说应是Modele） B：output root目录描述了当前项目的编译目录及适配服务。

确定之后当前项目的结构：

![技术分享][797348-20160224233751083-1977822404.png]

*  如有需要，添加lib包

![技术分享][797348-20160225001330536-185190312.png]

![技术分享][797348-20160225001337255-2034413311.png]

# 部署服务器 #

![技术分享][797348-20160224233904818-1626127517.png]

*  添加服务器

![技术分享][797348-20160224233918646-1203588879.png]

*  部署

注：很多童鞋在这里找不到Arifact，请参考部署项目中的Modules的配置。如果没有为项目配置Web服务组件，那么就没有Artifact。（当前项目连Web项目都不是，哪儿来的Artifact，又部署什么呢？）

![技术分享][797348-20160224234005068-1029599599.png]

*  注意下面的选择：

![技术分享][797348-20160224234103880-734957972.png]

# 编写代码测试 #

*  创建一个java类。可看到继承HttpServlet出问题了--这是因为没有把Tomcat的依赖加入Module

![技术分享][797348-20160225002926099-94225678.png]

*  在Modules加入Tomcat依赖

![技术分享][797348-20160225002941833-5215041.png]

![技术分享][797348-20160225002953630-1950910896.png]

![技术分享][797348-20160225003003427-157546013.png]

添加完毕

![技术分享][797348-20160225003011318-295062355.png]

*  现在按快捷键就可以了
