maven创建多模块项目＋springMVC+mybatis

在平时的javaweb项目中便于后期的维护，我们会进行分层开发，最常见的分为utils(常用公共方法),domain（模型层）,dao（数据库访问层）,service（业务逻辑层）,web（表现层），这样分层之后，各个层之间的职能比较明确，便于后期的维护，今天我们就使用maven多模块来构建以上各个层。
本项目详细代码下载地址：http://download.csdn.net/detail/chendaoqiu/8820949
项目结构如下：
movieInvest
|—-pom.xml
|—-movieInvest-utils
|—-pom.xml
|—-movieInvest-domain
|—-pom.xml
|—-movieInvest-dao
|—-pom.xml
|—-movieInvest-service
|—-pom.xml
|—-movieInvest-web
|—-pom.xml
1.创建movieInvest项目
创建maven项目的我们上一节有详细的讲述，这里再讲述一遍
1.1新建
1.2选择项目类型
1.3填写groupId，ArtifactId
打开pom.xml
添加一行
<packaging>pom</packaging>在把文件java Resource下的所有文件删除，因为此项目是做管理，不需要任何代码，只需要pom.xml文件
2.创建子项目movieInvest-utils
在创建好的项目上new一个，选择如下图 
填写子项目名 
选择类型
一直到完成
打开项目movieInvest-utils的pom.xml
添加一行
<packaging>jar</packaging>3.创建movieInvest-domain，movieInvest-dao，movieInvest-service
创建这三个子项目都是和创建movieInvest-utils一样，这里就不再讲述了
4.创建movieInvest-web
在创建好的项目上new一个，选择如下图
填写项目名 
选择项目类型 
点击完成 
打开pom.xml增加一行
<packaging>war</packaging>这里我们打开movieInvest项目的pom.xml下，我们观察可以看到增加了几行
<modules> <module>movieInvest-utils</module> <module>movieInvest-dao</module> <module>movieInvest-domain</module> <module>movieInvest-service</module> <module>movieinvest-web</module> </modules>4.添加各个子项目的关系
dao层添加依赖domain和utils
在dao项目中的pom.xml添加
<dependency> <groupId>com.yaozhitech</groupId> <artifactId>movieInvest-domain</artifactId> <version>${project.version}</version> </dependency> <dependency> <groupId>com.yaozhitech</groupId> <artifactId>movieInvest-utils</artifactId> <version>${project.version}</version> </dependency>service层依赖domain，utils，dao层
在service项目中的pom.xml添加
<dependency> <groupId>com.yaozhitech</groupId> <artifactId>movieInvest-domain</artifactId> <version>${project.version}</version> </dependency> <dependency> <groupId>com.yaozhitech</groupId> <artifactId>movieInvest-utils</artifactId> <version>${project.version}</version> </dependency> <dependency> <groupId>com.yaozhitech</groupId> <artifactId>movieInvest-dao</artifactId> <version>${project.version}</version> </dependency>web层添加service，domain，utils
在web项目中的pom.xml添加
<dependency> <groupId>com.yaozhitech</groupId> <artifactId>movieInvest-utils</artifactId> <version>${project.version}</version> </dependency> <dependency> <groupId>com.yaozhitech</groupId> <artifactId>movieInvest-domain</artifactId> <version>${project.version}</version> </dependency> <dependency> <groupId>com.yaozhitech</groupId> <artifactId>movieInvest-service</artifactId> <version>${project.version}</version> </dependency>5，配置spring＋mybatis
在movieInvest项目中的pom.xml中引入jar包
pom.xml配置信息如下
