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>pompackaging>

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>jarpackaging>

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>warpackaging>

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

    <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.yaozhitechgroupId>
      <artifactId>movieInvest-domainartifactId>
      <version>${project.version}version>
    dependency>
    <dependency>
      <groupId>com.yaozhitechgroupId>
      <artifactId>movieInvest-utilsartifactId>
      <version>${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.yaozhitechgroupId>
      <artifactId>movieInvest-domainartifactId>
      <version>${project.version}version>
    dependency>
    <dependency>
      <groupId>com.yaozhitechgroupId>
      <artifactId>movieInvest-utilsartifactId>
      <version>${project.version}version>
    dependency>
    <dependency>
      <groupId>com.yaozhitechgroupId>
      <artifactId>movieInvest-daoartifactId>
      <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.yaozhitechgroupId>
      <artifactId>movieInvest-utilsartifactId>
      <version>${project.version}version>
    dependency>
    <dependency>
      <groupId>com.yaozhitechgroupId>
      <artifactId>movieInvest-domainartifactId>
      <version>${project.version}version>
    dependency>
    <dependency>
      <groupId>com.yaozhitechgroupId>
      <artifactId>movieInvest-serviceartifactId>
      <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

<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">
