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：

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

maven 编译子模块 maven创建子模块_spring

1.2选择项目类型

maven 编译子模块 maven创建子模块_maven_02

1.3填写groupId，ArtifactId

maven 编译子模块 maven创建子模块_mybatis_03

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

maven 编译子模块 maven创建子模块_maven 编译子模块_04

填写子项目名

maven 编译子模块 maven创建子模块_srping_05

选择类型

maven 编译子模块 maven创建子模块_maven_02

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

maven 编译子模块 maven创建子模块_maven 编译子模块_04

填写项目名

maven 编译子模块 maven创建子模块_mybatis_08

选择项目类型

maven 编译子模块 maven创建子模块_maven 编译子模块_09

点击完成

maven 编译子模块 maven创建子模块_srping_10

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

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