IDEA14创建Maven管理的SpringMVC+Mybatis，web项目

## 项目构建步骤 ##

### 1、File->New->Project ###

勾选Create from archetype

![SouthEast][]

点击Next

### 2、输入GroupId、ArtifactId ###

![SouthEast 1][]

点击Next

![SouthEast 2][]

### 3、继续点击Next，输入Project name ###

![SouthEast 3][]

点击Finish，完成基本项目创建

![SouthEast 4][]

### 4、在src/main下添加java目录作为源文件目录 ###

在main上右键new Directory并命名为java；

同时在Project Structure中，将java目录设置为Sources，然后Apply，点击OK。

### 5、配置pom.xml ###

可以在maven仓库进行相关依赖搜索：http://www.mvnrepository.com/

利用<dependency>元素进行项目所依赖的jar包配置，maven通过对pom.xml的配置使得不再需要导入jar包那么麻烦

### 6、配置tomcat ###

### 7、资源文件编译时一起打包到输出目录 ###

IDEA的maven项目中，默认源代码目录下的xml等资源文件并不会在编译的时候一块打包进classes文件夹，而是直接舍弃掉。

项目中可能包含一些静态资源如：mapping/\*.xml，又或者一些spring的配置文件:spring.xml、spring-mvc.xml等等。这些静态资源都要配置到target目录下才能保证项目运行，否则会报找不到运行所需的这些文件。

target目录设置，如下图：

![SouthEast 10][]

pom.xml在resources中配置静态资源文件的目录：

<resources>
        
        <resource>
            <targetPath>whu/edu/irlab/mapping/</targetPath>
            <directory>src/main/java/whu/edu/irlab/mapping/</directory>
            <includes>
                <include>*.xml</include>
            </includes>
        </resource>
        <resource>
            <directory>src/main/resources</directory>
        </resource>
    </resources>

在pom.xml配置后可以看见target目录如下，配置的静态资源文件被包含进来了

## MavenDemo简单实例 ##

### 1、项目结构 ###

![SouthEast 12][]

注：  在WEB-INFO/lib下存放有jstl.jar和standard.jar，需要将其导入项目的Libraries中(一般使用Maven不这样做，直接在pom.xml里面配置响应的jar包依赖就行，当时自动填补依赖有些问题故采取比较麻烦的方式做)

如图：

### 2、pom.xml配置 ###
