IntelliJ IDEA之Maven工程多模块继承和聚合创建(详解)

一、前言
IntelliJ IDEA开发环境搭建：具体参考《IntelliJ IDEA教程之如何配置Maven》
Maven环境搭建：具体参考《Windows下Maven安装以及配置》

主要模拟企业开发是如何搭建Maven工程的，以Spring+SpringMVC+MyBatis为框架搭建，搭建环境Windows8系统，使用IntelliJ IDEA搭建Maven工程或者项目。

二、步骤
首先，我们创建一个新的工作空间

点击File ->New-Project...，弹出以下界面

点击Next

 点击Finish，进入到一个新的工作空间

创建queen-parent工程
点击File ->New->Module...，进入以下界面

点击Next，填写组织名称和项目名称，以及版本号(GAV)

点击Next

点击Next，父工程最后一步，给Module取名及选择工作目录

点击Finish，完成，如图：

注意：项目的打包方式为pom

创建公用工程queen-common

点击File->New->Module...，进入以下界面，请按照下图红色框框进行选中

点击Next

点击Next

点击Next

点击Finish，创建成功

Pom文件如下：

<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/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.queen.common</groupId>
    <artifactId>queen-common</artifactId>
    <parent>
        <groupId>com.queen.parent</groupId>
        <artifactId>queen-parent</artifactId>
        <version>1.0-SNAPSHOT</version>
    </parent>
</project>

注意：项目的打包方式为jar和父项目有所不同

创建queen-manage
跟前面创建queen-parent步骤类似，就不再赘述了，注意：下面打包方式为pom

点击Finish，创建成功

pom文件如下

<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/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.queen.manage</groupId>
    <artifactId>queen-manage</artifactId>
    <packaging>pom</packaging>
    <parent>
        <groupId>com.queen.parent</groupId>
        <artifactId>queen-parent</artifactId>
        <version>1.0-SNAPSHOT</version>
    </parent>
</project>

接下来我们创建工程queen-manage的子模块工程queen-manage-pojo

点击Next

点击Next

点击Next

点击Finish完成
紧接着我们依次创建queen-manage-mapper，queen-manage-service，queen-manage-controller工程，步骤跟queen-manage-pojo一样。

注意：在我们创建queen-manage-controller时，打包方式要选择war。

最终我们新建的所有工程如下：

现在我们要整理一下子工程之间的依赖关系
queen-manage-controller-依赖-queen-manage-service-依赖-queen-manage-mapper-依赖-queen-manage-pojo
上面可知，我们的依赖关系如此。
那我们修改一下pom文件

在queen-manage-mapper的pom文件中加入queen-manage-pojo的坐标

<dependency>
    <groupId>com.queen.manage</groupId>
    <artifactId>queen-manage-pojo</artifactId>
    <version>0.0.1-SNAPSHOT</version>
</dependency>

在queen-manage-service的pom文件中加入queen-manage-mapper的坐标

<dependency>
    <groupId>com.queen.manage</groupId>
    <artifactId>queen-manage-mapper</artifactId>
    <version>0.0.1-SNAPSHOT</version>
</dependency>

在queen-manage-controller的pom文件中加入queen-manage-service的坐标

<dependency>
    <groupId>com.queen.manage</groupId>
    <artifactId>queen-manage-service</artifactId>
    <version>0.0.1-SNAPSHOT</version>
</dependency>

各个工程中导入依赖

在queen-manage-controller工程的pom文件完整依赖：

运行工程，这里我们使用Maven Tomcat Plugin运行web项目

点击主界面右上角，进入以下界面

 

 注意：运行之前，每个工程需要clean和install一下 ，否则启动不了，如果你不知道IDEA如何使用Maven的clean功能，请参考这篇文章《IntelliJ IDEA教程之如何clean或者install Maven项目》
web.xml配置如下

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    id="WebApp_ID" version="2.5">
    <display-name>queen-manage</display-name>
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
 
</web-app>

index.jsp文件如下：

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>index</title>
</head>
<body>
    Welcome：queen
</body>

点击主界面右上角绿色三角形运行项目
运行起来之后，我们访问一下服务http://localhost:8080/index.jsp
